Description

Cosmetic preparations containing plant extracts

Field of the Invention

The invention is in the field of cosmetics and relates to preparations containing special plant extracts and the use of these plant extracts in cosmetic and / or pharmaceutical preparations, for example for skin treatment.

State of the art

Plant extracts have been used in many different cultures for medical as well as for cosmetic purposes for many years. New plants are extracted again and again and the extracts are examined for their cosmetic effects in order to find other plants with a new or changed spectrum of activity. Many plants, the benefits of which were not yet known, and which were considered to be exotic and insignificant, are widely used today, among others, in cosmetics.

Cosmetic preparations are available to the consumer in a variety of combinations today. Not only is it expected that these cosmetics have a certain nourishing effect or remedy a certain deficiency, but more and more often products are required that have several properties at the same time and thus show an improved range of services. Of particular interest are substances that both positively influence the technical properties of the cosmetic product, such as storage stability, light stability and formulability, and at the same time represent active ingredients that have nourishing, moisturizing, anti-irritant, anti-inflammatory and / or light-protective properties for the skin and / or hair convey. Good skin tolerance and the use of natural products by the customer are particularly important.

In addition, there is a general need to provide cosmetic and pharmaceutical preparations which, due to their special composition, have good technical properties and which are also characterized by additional properties for skin and hair.

Description of the invention

The object of the present invention was to provide cosmetic and / or pharmaceutical preparations which meet the requirements for cosmetic formulations, such as storage stability and skin tolerance, and additionally improved moisture-regulating, nourishing and protective properties for human skin and / or hair have. Another task has been to obtain plant extracts from plants that were previously unknown for cosmetic use and to make their ingredients usable as active ingredients in cosmetic and / or pharmaceutical preparations. The invention relates to extracts of the Mourera fluviatilis plant.

For the purposes of the present application, the term plant means both whole plants and parts of plants (leaves, flowers, roots) and mixtures thereof.

Mourera fluviatilis

The extracts to be used according to the invention are obtained from plants of the Podostemaceae family and are extracts of the Mourera fluviatilis plant. This plant is a filament family, which mainly occur in tropical, fast-flowing watercourses and waterfalls. The plant is native to North-South America and French Guyana where it is also called "Coumarou salad". The plant has racemous inflorescences, the so-called inflorescences with double-coated bracts. These inflorescences contain 14 - 40 dust bags.

extraction

The extracts to be used according to the invention are produced by customary methods of extracting plants or parts of plants. Regarding the suitable conventional extraction methods such as maceration, remaceration, digestion, movement maceration, vortex extraction, ultrasound extraction, countercurrent extraction, percolation, repercolation, evacolation (extraction under reduced pressure), diacolation and solid-liquid extraction under continuous reflux , which is carried out in a Soxhlet extractor, which is familiar to a person skilled in the art and in principle all can be used, is exemplary of Hager's Handbook of Pharmaceutical Practice, (5th Edition, Vol. 2, pp. 1026-1030, Springer Verlag, Berlin- Heidelberg-New York 1991). Fresh plants or parts of plants can be used as the starting material, but usually dried plants and / or parts of plants are used, which can be mechanically comminuted before extraction. All grinding methods known to the person skilled in the art are suitable here, for example crushing with a mortar.

Organic solvents, water (distilled or non-distilled, preferably hot water at a temperature above 80 ° C.) or mixtures of organic solvents and water, in particular low molecular weight alcohols, esters, hydrocarbons, ketones or halogen-containing hydrocarbons, can preferably be used as solvents for carrying out the extractions with more or less high water contents. Extraction with water, methanol, ethanol, pentane, hexane, heptane, acetone, propylene glycols, polyethylene glycols, ethyl acetate, dichloromethane, trichloromethane and mixtures thereof is particularly preferred. The extraction is usually carried out at 20 to 100 ° C, preferably at 30 to 90 ° C, in particular at 60 to 85 ° C. In one possible embodiment, the extraction takes place under an inert gas atmosphere to avoid oxidation of the ingredients of the extract. The extraction times are set by the person skilled in the art depending on the starting material, the extraction process, the extraction temperature, the ratio of solvent to raw material, etc. After extraction If necessary, the crude extracts obtained can be subjected to further customary steps, such as purification, concentration and / or decolorization. If desired, the extracts produced in this way can, for example, be subjected to a selective separation of individual undesirable ingredients. The extraction can be carried out to any desired degree of extraction, but is usually carried out until exhaustion. Typical yields (= dry matter amount of the extract based on the amount of raw material used) in the extraction of dried plants are in the range from 3 to 20, in particular 4 to 16,% by weight. The present invention includes the knowledge that the extraction conditions and the yields of the final extracts can be selected depending on the desired field of use. If desired, the extracts can then be subjected to spray drying or freeze drying, for example.

The invention furthermore relates to cosmetic and / or pharmaceutical preparations which contain an extract of the Mourera fluviatilis plant.

Cosmetic and / or pharmaceutical preparations based on the Mourera fluviatilis plant show surprisingly good nourishing and protective properties for skin and hair, against stress and environmental influences, and at the same time good skin tolerance. Furthermore, the preparations obtained in this way are good moisture-regulating moisturizers for the skin. The preparations obtained in this way are furthermore distinguished by a high antioxidative capacity, which on the one hand protects the skin from inflammatory reactions and against oxidative skin aging processes, and on the other hand the cosmetic ones Protected against oxidative degradation (spoilage). In addition, the products obtained in this way are suitable for counteracting the damage to human fibroblasts and keratinocytes by UV radiation and can therefore be used as a sunscreen in cosmetics.

The amount of plant extracts used in the preparations mentioned depends on the concentration of the individual ingredients and on the manner in which the extracts are used. In general, 0.01 to 25 parts by weight ⁰ / ", in particular 0.03 to 10, and especially 0.1 to 5 wt .-% of the plant extract -bezogen on the final cosmetic and / or pharmaceutical compositions employed, with the proviso that the amounts stated add up to 100% by weight with further auxiliaries and additives and with water.

The total proportion of auxiliaries and additives can be 1 to 50, preferably 5 to 40% by weight, based on the final preparation of the cosmetic and / or pharmaceutical preparations. The preparations can be produced by customary cold or hot processes; the phase inversion temperature method is preferably used.

extracts:

The extracts of the Mourera fluviatilis plant according to the invention generally contain ingredients from the group consisting of, saponins, flavone derivatives, sterols, triterpenes, xanthone derivatives and / or carotenoids. These are composed differently depending on the selected starting material and the selected extraction method.

For the purposes of the invention, saponins are understood to be those saponins which can be isolated from the Mourera fluviatilis plant. In particular, it is a group of glycosides that form colloidal, soap-like solutions in water. The saponins are divided into steroid saponins and triterpene saponins according to the type of their aglycones, the sapogenins.

For the purposes of the present invention, flavone derivatives are to be understood as those which can be isolated from the Mourera fluviatilis plant. In particular, they are substances which are hydrogenation, oxidation or substitution products of 2-phenyl-4H-1-benzopyran, where hydrogenation may already be present in the 2,3-position of the carbon skeleton, oxidation in the 4- Position may already exist, and substitution products are understood to mean the replacement of one or more hydrogen atoms by hydroxyl or methoxy groups. This definition therefore includes flavans, flavan-3-oles (catechins), flavan-3,4-diols (leucoanthocyanidins), flavones, flavonols and flavanones in the conventional sense.

For the purposes of the invention, sterols are to be understood as steroids which can be isolated from the Mourera fluviatilis plant. In particular, they are steroids that only have a hydroxyl group at C-3, but otherwise no functional group, that is to say formally alcohols. In addition, the sterols containing 27 to 30 C atoms generally have a C = C double bond in the 5/6 position, more rarely also / or in 7/8, 8/9 and other positions (e.g. 22/23) , For the purposes of the invention, triterpenes are understood to mean those triterpenes which can be isolated from the Mourera fluviatilis plant. The triterpenes according to the invention can be formally understood as polymerization products of the hydrocarbon isoprene. The triterpenes (C30) are formed from three isoprene residues. Different polycyclic ring systems for the possible triterpenes can be derived from different folding options of the three isoprene residues. The cyclization preferably gives 6 rings, in addition to most tetra- (e.g. cucurbitacins) and some pentacyclic (e.g. Lupane) triterpenes 5-rings. Since the 6-rings are in the form of armchairs and tubs, the 5-rings can be flat or angled, many different scaffolds are possible.

For the purposes of the invention, xanthone derivatives are to be understood as those which can be isolated from the Mourera fluviatilis plant. These are derivatives of dibenzo-gamma-pyrone. The xanthone derivatives are referred to synonymously as 9-xanthenone derivatives. The xanthone derivatives according to the invention are preferably 6-deoxyjacareubin and / or trapezium xanthone. The 9-xanthenones can furthermore preferably be present as hydroxy- and / or methoxy-substituted xanthenones, such as, for example, gentian acid. The majority of the derivatives of the xanthones are light yellow in color and have a light blue fluorescence. For the purposes of the present invention, carotenoids are to be understood as those which can be isolated from the Mourera fluviatilis plant. In particular, they are substances that are chemically considered 11 to 12 times unsaturated tetraterpenes with a basic structure with 9 conjugated Double bonds, 8 methyl branches (including the possible ring structures) and a ß-ionon ring structure at one end of the molecule, while they differ in the structure of the other end of the molecule. Typical carotenoids are, for example, β-carotene or provitamin A, α-carotene, lutein, cryptoxanthin, zeaxanthin and lycopene. On the use of carotenoids in systemic light protection, Heinrich et al. in Parf.Kosm. 78, 10 (1997).

In a particular embodiment of the invention, the extracts of the Mourera fluviatilis plant contain minerals in the form of salts of the alkali or alkaline earth metals. The predominant metals are sodium, potassium or calcium. The alkali or alkaline earth metals occur in the form of their salts, but predominantly in the form of their halides, oxides or hydroxides, phosphates, carbonates, sulfates or nitrates.

The present invention includes the finding that particularly effective cosmetic agents are obtained by the interaction of the ingredients of the plant extracts, in particular the abovementioned.

Further objects of the invention relate to the varied use of the plant extracts from Mourera fluviatilis, for example

• in skin and hair care products, especially for stress;

• in moisture regulating humectants;

Cleaning products:

Care products for the purposes of the invention are care products for skin and hair. These care products include, among other things, cleaning and building effects as well as moisture-regulating and UV light protection properties. In principle, the extracts according to the invention can be used in all cosmetic products. Examples of cosmetic products are described in their formulations in Table 7 to Table 15.

The aim of hair care is to maintain the natural state of freshly regrown hair for as long as possible or to restore it if it is damaged. Characteristics of natural healthy hair are silky shine, low porosity, resilient yet soft fullness and a pleasantly smooth feeling (good "grip"). The care products according to the invention have a smoothing effect on the hair, they improve combability, reduce the electrostatic charge and improve the feel and shine.

The preparations according to the invention show an excellent skin-care effect with high skin tolerance at the same time. In addition, they show good stability, in particular against oxidative decomposition of the products.

Humectant:

For the purposes of the invention, moisture-regulating humectants are to be understood as skin care products which serve to regulate the moisture of the skin. This corresponds in the sense of the invention the definition of a moisturizer. It is substances or mixtures of substances that give cosmetic and / or pharmaceutical preparations the property of reducing the moisture release of the stratum corneum (horny layer) after application and distribution on the skin surface.

The humectants according to the invention contain extracts of the Mourera fluviatilis plant. Additional humectants, for example, may be present as further humectants in combination with the plant extract, such as:

Polyglycerol fatty acid esters based on fatty acids with 12-18 C atoms, e.g. Tetraglyceryl monooleate, triglyceryl diisostearate;

Pyroglutamic acid or L-arginine pyroglutamate, L-lysine pyroglutamate; Mixtures of amino acids such as L-alanine, L-arginine, L-serine, L-threonine; Propylene glycol acetamide

Polysaccharides or hyaloronic acid castor oil ether and sorbitan esters as described in JP60149511 (Lion Corp)

Sunscreen or UV light protection factors

Another object of the invention is the use of the extracts of the Mourera fluviatilis plant in sunscreens.

Sunscreens or UV light protection factors in the sense of the invention are light protection agents which are useful for protecting human skin against the damaging effects of direct and indirect radiation from the sun. The sun's ultraviolet radiation responsible for tanning the skin is divided into the sections UV-C (wavelengths 200-280 nm), UV-B (280-315 nm) and the like. UV-A (315 ^ 100 nm).

The pigmentation of normal skin under the influence of solar radiation, i.e. H. the formation of melanins is UV-B u. UV-A causes different. Irradiation with UV-A rays ("long-wave UV") results in the darkening of the melanin bodies already present in the epidermis, without any harmful effects being recognizable. This is different with the so-called "short-wave UV" (UV-B) , This causes the development of so-called late pigment through the formation of new melanin grains. However, before the (protective) pigment is formed, the skin is exposed to unfiltered radiation, which - depending on the duration of exposure - leads to the formation of reddened skin (erythema), skin inflammation (sunburn) and the like. can even cause blisters.

Extracts of the Mourera fluviatilis plant are used as UV absorbers or light filters, which convert the UV radiation into harmless heat. These can also be present in combination with other sunscreens or UV light protection factors.

These further UV light protection factors are, for example, liquid or crystalline organic substances (light protection filters) present at room temperature which are capable of blocking ultraviolet rays absorb and release the absorbed energy in the form of longer-wave radiation, eg heat. UVB filters can be oil-soluble or water-soluble. Examples of oil-soluble substances are:

> 3-benzylidene camphor or 3-benzylidene norcampher and its derivatives, e.g. 3- (4-methylbenzylidene) camphor as described in EP 0693471 B1;

> 4-aminobenzoic acid derivatives, preferably 2-ethylhexyl 4- (dimethylamino) benzoate, 2-octyl 4- (dimethylamino) benzoate and amyl 4- (dimethylamino) benzoate;

> Esters of cinnamic acid, preferably 4-methoxycinnamic acid 2-ethylhexyl ester, 4-methoxycinnamic acid propyl ester, 4-methoxycinnamic acid isoamyl ester 2-cyano-3,3-phenylcinnamic acid 2-ethylhexyl ester (octocrylene);

> Esters of salicylic acid, preferably salicylic acid 2-ethylhexyl ester, salicylic acid 4-isopropylbenzyl ester, salicylic acid homomethyl ester;

> Derivatives of benzophenone, preferably 2-hydroxy-4-methoxybenzophenone, 2-hydroxy-4-methoxy-4'-methylbenzophenone, 2,2'-dihydroxy-4-methoxybenzophenone;

> Esters of benzalmalonic acid, preferably di-2-ethylhexyl 4-methoxybenzmalonate;

> Triazine derivatives, e.g. 2,4,6-trianilino- (p-carbo-2'-ethyl-1 '-hexyloxy) -1, 3,5-triazine and octyl triazone as described in EP 0818450 A1 or dioctyl butamido triazone (Uvasorb ® HEB);

> Propane-1,3-dione, e.g. 1 - (4-tert-butylphenyl) -3- (4'methoxyphenyl) propane-1,3-dione;

> Ketotricyclo (5.2.1, 0) decane derivatives, as described in EP 0694521 B1.

Possible water-soluble substances are:

> 2-phenylbenzimidazole-5-sulfonic acid and its alkali, alkaline earth, ammonium, alkylammonium, alkanolammonium and glucammonium salts;

> Sulfonic acid derivatives of benzophenones, preferably 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid and its salts;

> Sulfonic acid derivatives of 3-benzylidene camphor, e.g. 4- (2-oxo-3-bomylidene-methyl) benzenesulfonic acid and 2-methyl-5- (2-oxo-3-bomylidene) sulfonic acid and their salts.

Derivatives of benzoylmethane, such as 1- (4'-tert-butylphenyl) -3- (4'-methoxyphenyl) propane-1, 3-dione, 4-tert-butyl-4, are particularly suitable as typical UVA filters '-methoxydibenzoyl-methane (Parsol 1789), 1-phenyl-3- (4'-isopropylphenyl) propane-1, 3-dione and enamine compounds, as described for example in DE 19712033 A1 (BASF). The UV-A and UV-B filters can of course also be used in mixtures. In addition to the soluble substances mentioned, insoluble light protection pigments, namely finely dispersed metal oxides or salts, are also suitable for this purpose. Examples of suitable metal oxides are, in particular, zinc oxide and titanium dioxide and, in addition, oxides of iron, zirconium, silicon, manganese, aluminum and cerium and mixtures thereof. Silicates (talc), barium sulfate or zinc stearate can be used as salts. The oxides and salts are used in the form of the pigments for skin-care and skin-protecting emulsions. The particles should have an average diameter of less than 100 nm, preferred have between 5 and 50 nm and in particular between 15 and 30 nm. They can have a spherical shape, but it is also possible to use particles which have an ellipsoidal shape or a shape which differs from the spherical shape in some other way. The pigments can also be surface-treated, ie hydrophilized or hydrophobicized. Typical examples are coated titanium dioxides such as titanium dioxide T 805 (Degussa) or Eusolex® T2000 (Merck). Silicones, and in particular trialkoxyoctylsilanes or dimethicones, are particularly suitable as hydrophobic coating agents. So-called micro- or nanopigments are preferably used in sunscreens. Micronized zinc oxide is preferably used. Further suitable UV light protection filters can be found in the overview by P.Finkel in SÖFW Journal 122, 543 (1996) and Perfumery and Cosmetics 3 (1999), page 11ff.

Another object of the invention is the use of extracts of the Mourera fluviatilis plant in agents against damage to fibroblasts and / or keratinocytes by UVA radiation and / or UVB radiation and as anti-inflammatory additives.

UVA rays penetrate into the Dennis, where they lead to oxidation stress, which is demonstrated by lipoperoxidation of the cytoplasmic membranes. The lipoperoxides are broken down to malonic aldehyde (MDA), which will cross-link many biological molecules such as proteins and nucleic bases (enzyme inhibition or mutagenesis). The extracts of the plant Mourera fluviatilis according to the invention significantly reduce the level of MDA in human fibroblasts which is induced by UVA rays and thus show a high capacity to reduce the harmful effects of oxidative stress on the skin.

UVB rays trigger inflammation by activating an enzyme, namely phospholipase A2 or PLA2. This inflammation (erythema, edema) is triggered by the removal of arachidonic acid from the phospholipids of the plasma membrane by the phospholipase. Arachidonic acid is the precursor to prostaglandins, which cause inflammation and cell membrane damage; the prostaglandins E2 (= PGE2) are formed by the cyclooxygenase. The level of release of the cytoplasmic enzyme LDH (lactate dehydrogenase) in human keratinocytes serves as a marker for cell damage.

The extracts of the Mourera fluviatilis plant according to the invention reduce the effect of UVB radiation on the number of keratinocytes and on the content of released LDH. The extracts therefore show the ability to reduce the damage to cell membranes caused by UVB radiation.

The use of the extracts according to the invention as anti-inflammatory additives is in principle possible for all cosmetic and / or pharmaceutical preparations which are used for inflammation of the skin and thus in skin care. The inflammation of the skin can have a variety of causes. Another object of the invention is the use of extracts of the Mourera fluviatilis plant as antioxidants or radical scavengers.

Antioxidants for the purposes of the invention are oxidation inhibitors which can be isolated from the Mourera fluviatilis plant. Antioxidants are able to inhibit or prevent the undesirable changes in the substances to be protected caused by the effects of oxygen and other oxidative processes. The effect of the antioxidants is mostly that they act as a radical scavenger for the free radicals that occur during autoxidation.

In addition to using extracts of the Mourera fluviatilis plant as antioxidants, other known antioxidants can also be used. One possible application of the antioxidants, for example in cosmetic and / or pharmaceutical preparations, is their use as secondary light stabilizers, because antioxidants are able to interrupt the photochemical reaction chain which is triggered when UV radiation penetrates the skin. In addition to the plant extract according to the invention, further typical examples are amino acids (e.g. glycine, alanine, arginine, serine, threonine, histidine, tyrosine, tryptophan) and their derivatives, imidazoles (e.g. urocanic acid) and their derivatives, peptides such as D, L-carnosine, D. -Camosin, L-carnosine and their derivatives (e.g. anserine), carotenoids, carotenes (e.g. α-carotene, β-carotene, lycopene, lutein) or their derivatives, chlorogenic acid and its derivatives, lipoic acid and its derivatives (e.g. dihydroliponic acid), aurothioglucose , Propylthiouracil and other thiols (e.g. thioredoxin, glutathione, cysteine, cystine, cystamine and their glycosyl, N-acetyl, methyl, ethyl, propyl, amyl, butyl and lauryl, palmitoyl, oleyl, γ-linoleyl, cholesteryl and glyceryl esters) and their salts, dilauryl thiodipropionate, distearyl thiodipropionate, thiodipropionic acid and their derivatives (esters, ethers, peptides, lipids, nucleotides, nucleosides and salts) as well as sulfoximine compounds (e.g. buthioninsulfoximines, homo cysteine sulfoximine, butioninsulfones, penta-, hexa-, heptathioninsulfoximine) in very low tolerable doses (e.g. pmol to μmol / kg), also (metal) chelators (e.g. α-hydroxy fatty acids, palmitic acid, phytic acid, lactoferrin), α-hydroxy acids (e.g. Citric acid, lactic acid, malic acid), humic acid, bile acid, bile extracts, bilirubin, biliverdin, boldin, boldo extract, EDTA, EGTA and their derivatives, unsaturated fatty acids and their derivatives (e.g. γ-linolenic acid, linoleic acid, oleic acid), folic acid and their derivatives , Ubiquinone and ubiquinol and their derivatives, vitamin C and derivatives (e.g. ascorbyl palmitate, Mg ascorbyl phosphate, ascorbyl acetate), tocopherols and derivatives (e.g. vitamin E acetate), vitamin A and derivatives (vitamin A palmitate) and coniferyl benzoate of benzoin , Rutinic acid and its derivatives, α-glycosylrutin, ferulic acid, furfurylidene glucitol, camosin, butylated hydroxytoluene, butylated hydroxyanisole, nordihydroguajak resin acid, nordihydroguajaretic acid, Trihydroxybutyrophenone, uric acid and its derivatives, mannose and its derivatives, superoxide dismutase, zinc and its derivatives (e.g. ZnO, ZnS0 ₄ ) selenium and its derivatives (e.g. selenium methionine), stilbene and their derivatives (e.g. stilbene oxide, trans-stilbene oxide) and the derivatives suitable according to the invention (salts, esters, ethers, sugars, nucleotides, nucleosides, peptides and lipids) of these active substances.

The person skilled in the art understands the term lecithins as those glycerophospholipids which are formed from fatty acids, glycerol, phosphoric acid and choline by esterification. Lecithins are therefore often referred to in the art as phosphatidylcholines (PC) and follow the general formula II.

Formula II

where R typically represents linear aliphatic hydrocarbon radicals with 15 to 17 carbon atoms and up to 4 cis double bonds. Examples of natural lecithins include the cephalins, which are also referred to as phosphatidic acids, and derivatives of 1,2-diacyl-sn-glycerol-3- represent phosphoric acids.

Cosmetic deodorants counteract, mask or eliminate body odors. Body odors arise from the action of skin bacteria on apocrine sweat, whereby unpleasant smelling breakdown products are formed. Accordingly, deodorants contain active ingredients which act as germ-inhibiting agents, enzyme inhibitors, odor absorbers or odor maskers.

In principle, all substances effective against gram-positive bacteria are suitable as germ-inhibiting agents, such as.

Further substances which can be considered as esterase inhibitors are sterol sulfates or phosphates, such as, for example, lanosterol, cholesterol, campesteric, stigmasterol and sitosterol sulfate or phosphate, dicarboxylic acids and their esters, such as, for example, glutaric acid, glutaric acid monoethyl ester, glutaric acid diethyl ester, adipic acid, Monoethyl adipate, diethyl adipate, malonic acid and diethyl malonate, hydroxycarboxylic acids and their esters such as citric acid, malic acid, tartaric acid or tartaric acid diethyl ester and zinc glycinate.

Suitable odor absorbers are substances that absorb odor-forming compounds and can retain them to a large extent. They lower the partial pressure of the individual components and thus also reduce their speed of propagation. It is important that perfumes must remain unaffected. Odor absorbers are not effective against bacteria. They contain, for example, a complex zinc salt of ricinoleic acid or special, largely odorless fragrances, which are known to the person skilled in the art as "fixators", such as, for example, the main component.

The dyes which can be used are those substances which are suitable and approved for cosmetic purposes, as compiled, for example, in the publication "Cosmetic Dyes" by the Dye Commission of the German Research Foundation, Verlag Chemie, Weinheim, 1984, pp. 81-106. These dyes are usually used in concentrations of 0.001 to 0.1% by weight, based on the overall preparation. Another object of the invention is a method for producing an extract of the plant Mourera fluviatilis in which solvents or mixtures of these solvents are used to extract the plant, which are selected from the group formed by distilled or undistilled water, low molecular weight alcohols, Esters or hydrocarbons.

Examples

Example 1: 300 g of dried Mourera fluviatilis plants were roughly crushed in a mortar, then transferred to a glass reactor and poured with 3 liters of distilled water. The infusion was heated between 80 and 85 ° C and extracted with stirring over a period of 1 h at this temperature. The mixture was then cooled to 20 ° C. and centrifuged for 15 minutes at a speed of 5000 g. The supernatant colloidal liquid was separated from the residue by filtration on depth filters with an average porosity of 0.450 μm (from the company Seitz, Bordeaux France), 1.7 1 extract being obtained, which had a dry residue of 2.4% by weight , The brown colored extract was spray-dried at a starting temperature of 185 ° C and a final temperature of 80 ^C C. The yield of dry product was 13.5% by weight, based on the dry weight of plants used.

Example 2: Example 1 was repeated, but after centrifuging the aqueous extract was adjusted to a pH = 7.2 + - 0.2 and filtered by filtration on depth filters with an average porosity of 0.200 μm.

Example 3: Example 1 was repeated, but the extraction was carried out with 3 1 80% by weight aqueous methanol. The extraction was carried out with stirring for 1 h at boiling temperature under reflux and the extract was further processed as described. The filtration was carried out as described in Example 1. The alcohol was then first removed at 45 ° C. under reduced pressure and then the green-brown residue was spray-dried as described. The yield of dry product was 15.9% by weight, based on the dry weight of plants used.

Example 4: Example 1 was repeated, but the extraction was carried out with 3 l 96% by weight aqueous ethanol. The extraction was carried out with stirring for 1 h at boiling temperature under reflux and the extract was further processed as described. The filtration was carried out as described in Example 1. Then the alcohol was first removed at 45 ° C. under reduced pressure and then the green residue was dried at 50 ° C. The yield of dry product was 4.9% by weight, based on the dry weight of plants used.

Example 5: 260 g of the dried residue from Example 4 were transferred to a glass reactor and 2.6 l of distilled water were added. The infusion was further treated as described in Example 1. The brown colored extract was spray dried at an initial temperature of 185 ° C and a final temperature of 80 ° C. The yield of dry product was 12.5% by weight, based on the dry weight of the dried residue used.

Example 6: Activity against free radicals.

The suitability of the extracts against oxidative stress was examined in a first series of tests. The extracts according to Examples 1 to 5 were each used in concentrations of 0% w / v (weight per volume); 0.03% w / v and 0.1% w / v. In a first test, the hydroxylation of salicylic acid by hydroxyl radicals (from the reaction of hydrogen peroxide with iron (III) ions and EDTA) was examined as a reference system. This reaction can be examined photometrically since the hydroxylation product of salicylic acid is reddish in color. The influence of the extracts on the formation of the hydoxysal icylic acid at an optical density of 490 nm was measured. The measurement results are summarized in Table 1; the degree of hydroxysalicylic acid formation is given in% absolute.

Table 1: Degree of hydroxylation of salicylic acid in% absolute (results are mean values from two measurements)

It can be seen from the values in Table 1 that the extracts used from the Maureria fluviatilis plant show an action against free radicals. Depending on the extraction process, differently effective extracts are obtained. According to an extraction method described in Example 1, e.g. a concentration of 0.072% w / v is sufficient to achieve a 50% inhibition of the radical reaction. The formation of hydroxysalicylic acid by hydroxy radicals is reduced by 50% at this concentration in this case.

In a third test, xanthine oxidase was chosen as the test system. In the case of oxidative stress, the enzyme causes the conversion of purine bases, such as, for example, adenine or guanine into uronic acid, the oxygen radicals formed as an intermediate being able to be detected by luminescence and reacted quantitatively by reaction with luminol. The luminescence yield is reduced in the presence of substances with radical-trapping properties.

Table 2: Degree of luminescence inhibition in% absolute

It can be seen from Table 2 that the extracts of the Mourera fluviatilis plant inhibit the radical formation of luminescence. Depending on the concentration and type of extraction process, different levels of inhibition are obtained. A concentration of 0.058% w / v one Extract prepared according to Example 3 already provides a 50% inhibition of luminescence formation and thus clearly shows radical-trapping properties.

Example 7: Cell protection action against UVA on human fibroblasts grown in vitro

Background: UVA rays penetrate into the dermis, where they lead to oxidation stress, which is demonstrated by lipoperoxidation of the cytoplasmic membranes.

The lipoperoxides are broken down to malonaldehyde, which will crosslink many biological molecules such as proteins and nucleic bases (enzyme inhibition or mutagenesis).

Method: To carry out these tests, a defined culture medium was inoculated with the fibroblasts with fetal calf serum and the plant extract (in the defined medium with 10% fetal calf serum) was added 72 hours after the inoculation.

After 48 hours of incubation at 37 ° C. and a CO 2 content of 5%, the culture medium was replaced by saline solution (physiological NaCl solution) and the fibroblasts were irradiated with a UVA dose (365 nm, 15 J / cm ² ; Tubes: MAZDA FLUOR TFWN40).

After the end of the irradiation, the MDA level (malonaldialdehyde level) in the supernatant sodium chloride solution was determined quantitatively by reaction with thiobarbituric acid.

Table 3: Quantification of malonaldialdehyde in fibroblasts (results in% relative to the control, mean value from 2 experiments, each with three repetitions

The results from Table 3 show that the extracts of the plant Mourera fluviatilis according to the invention significantly reduce the level of MDA in human fibroblasts, which is induced by UVA rays. These results show a high capacity of Mourera fluviatilis extracts to reduce the harmful effects of oxidative stress on the skin.

Example 8: Cell protection action against UVB on human keratinocytes grown in vitro

Background: UVB rays trigger inflammation (erythema, edema) by activating an enzyme, namely phospholipase A2 or PLA2, which removes arachidonic acid from the phospholipids of the plasma membrane. Arachidonic acid is the precursor to prostaglandins, which cause inflammation and cell membrane damage; the prostaglandins E2 (= PGE2) are formed by the cyclooxygenase. Method: The effect of UVB radiation was investigated on keratinocytes in vitro by determining the release of the cytoplasmic enzyme LDH (lactate dehydrogenase). This enzyme serves as a marker for cell damage.

In order to carry out the tests, a defined medium, which contains fetal calf serum, was inoculated with the keratinocytes and the plant extract (diluted with saline solution) was added 72 hours after the inoculation.

The keratinocytes were then irradiated with a UVB dose (30 mJ / cm ² - tubes: DUKE FL40E).

After a further 1 day incubation at 37 ° C and at 5% CO ₂ , the LDH content in the supernatant was determined. The content of LDH- (lactate dehydrogenase) was determined by means of an enzyme reaction (kit used to investigate the LDH content by the company Röche). The number of adherent keratinocytes is determined (after trypsin treatment) with a particle counter.

Table 4: Cell protection effect of an extract from Mourera fluviatilis against UVB rays; Results in% based on the control, average of 2 attempts, each with two repetitions

The results of these tests prove that an extract of the Mourera fluviatilis plant according to the invention reduces the effect of UVB radiation on the number of keratinocytes and on the content of released LDH. The extracts described accordingly show the ability to reduce the damage to cell membranes caused by UVB radiation.

Example 9: Sensory activity on human hair

The evaluation of the modification of sensory properties on human hair after treatment with extracts of the Mourera fluviatilis plant was carried out on standardized strands of hair (15 cm in length and 3 g in weight). An aqueous sodium lauryl sulfate solution (15% w / v) served as standard and placebo. The samples of the plant extracts were incorporated and tested in a concentration of 1.5% w / v in the sodium lauryl sulfate solution. The treatment effects were investigated on three different hair types: a) control hair: the tresses were washed with an aqueous sodium lauryl sulfate solution (15% w / v). b) Bleached hair: the strands were washed with a bleaching shampoo containing 6% H2O2 and ammonia (Eclair clair from L'Oreal), 30 min. treated and then washed with the aqueous sodium lauryl sulfate solution (15% w / v). This bleaching process was repeated twice. c) Permanent wavy hair: the strands were washed with a sodium mercaptoacetate solution (6% w / v, pH = 6) for 20 min. treated, rinsed and then mixed with a solution of H2O2 (pH = 3) for 10 min. After this solution was rinsed out again, it was washed with aqueous sodium lauryl sulfate solution (15% w / v). This permanent wave cycle was repeated twice.

The strands of hair thus prepared were held in the solution with the respective test substance for 3 minutes and then rinsed out for 1 minute. After rinsing, the strands of hair were combed and their wet combability was tested. The tresses were dried at room temperature. The sensory tests were carried out on dry hair 24 hours after treatment with the extracts.

The following properties were determined on dry hair: combability, smoothness and softness, electrostatic charge, volume and shine.

The table shows the results of sensory tests on wet and dry hair. The sensory properties can be read in comparison to standardized strands of hair. The higher the number given, the better the assessment of the respective sensory property.

Table 5 Sensory properties of human hair tresses after treatment with extracts of the Mourera fluviatilis plant compared to untreated hair tresses

The results of the tests show that an extract from the Mourera fluviatilis plant improves the sensory properties of human hair. A significant improvement in combability on wet hair, softness, volume and shine could be demonstrated for the control hair after treatment. The electrostatic charge decreased after treatment with the plant extract.

In bleached hair, there was an improvement in combability and volume in wet hair and a reduction in static electricity. For permed hair, the combability on dry hair and the softness increased. Example 10: Test for skin moisture regulation

Background: The horny layer (the stratum corneum) is found in the epidermis of human skin. The stratum corneum is a dielectric medium with little electrical conduction. The water content leads to increased dielectric conductivity and the determination of the dielectric conductivity of the stratum corneum can thus serve as a measure of the degree of moisture in human skin. The increase in the dielectric conductivity of the stratum corneum reflects an increased level of moisture in the human skin.

Method: The following formulation for cosmetic preparations, which was used to test the moisture-regulating properties of the formulation, may be mentioned as an example.

Pyroglutamic acid: 11.2%

L-Alanine: 7.2%

L-arginine: 17.0%

L-serine: 20.5%

L-threonine: 3.1%

Dry extract according to example 2: 1.0%

Sucrose: 40.0%

Samples of normal skin obtained from plastic surgery were used for this test. The stratum corneum from these skin samples was stored and standardized in chambers with defined relative humidity (44%, saturated solution of potassium carbonate). Each sample of the stratum corneum was tested for comparison under four conditions.

1) without treatment;

2) treatment with placebo;

3) treatment with a preparation consisting of a hydrogel (Hydrogel LS from Laboratoire Serobiologique LS), containing 2% w / v of the moisture-regulating preparations described above;

4) Treatment with a preparation consisting of a hydrogel (Hydrogel LS from Laboratoire Serobiologique LS) containing 4% w / v of the moisture-regulating preparations described above.

The hydrogel (Hydrogel LS from Laboratoire Serobiologique LS) served as a placebo without the preparation described, that is to say without a plant extract.

The moisture-regulating activity of the preparation described above was determined as a percentage increase in the conductivity compared to the placebo treatment.

A dose-dependent moisture-regulating activity can be seen from the results.

Table 6 Moisture-regulating effect, determined by measuring the dielectric conductivity (in μS); Average of 18 examinations (the standard deviation is in brackets)

The results above show that the examined and tested extracts of the Mourera fluviatilis plant have the following abilities:

- trapping and neutralizing radicals and reactive forms of oxygen;

- Reduction of the degree of lipoperoxidation induced by UVA rays on human fibroblasts;

- Reduction of cell damage induced by UVB on human keratinocytes;

- With regard to cosmetics, sensory examinations on human hair revealed a clear build-up, softening and glossy effect and improved combability;

- A preparation containing extracts of the Mourera fluviatilis plant showed significant moisture-regulating abilities.
