Description

Antioxidant, anti-inflammatory and anti-pollution composition containing extract of Myrtus communis and Sparassis crispa
Technical Field
The present invention relates to an antioxidant, anti-inflammatory and anti-pollution composition comprising a mixed extract of myrtle and sparassis crispa.
Background
The fine dust is dust having a particle size of 10 μm or less, abbreviated as PM10(Particulate Matter 10), and the ultrafine dust having a particle size of 2.5 μm or less is classified as PM2.5(Particulate Matter 2.5). It is mainly produced when fossil fuels are burned, and fine dust from china, which relies on coal to a degree of 70%, accounts for a large part. In addition, yellow sand is a phenomenon that fine sand, loess and dust in deserts of the places such as china and mongolian countries in the middle of the continental asia and in loess areas float in the sky, fly to the upper layer of the air and are blown away by wind, and may fall into the ju-zhou island as an air pollutant which can move in a long distance.
In particular, when fine dust comes into direct contact with the skin, which is located at the outermost part of our body, the skin acts as a barrier between the organisms and the external environment, and if it is frequently exposed directly to pollution, the barrier is lowered, thereby causing various problems. In particular, the fine dust is 20 times smaller than pores and easily permeates into human skin. For example, the skin is considered to be a major site for absorbing pollutants in the environment, as well as inhaling toxic substances such as chloroform and the like through the respiratory system.
Fine dust causes oxidative stress and inflammation in the body or skin. Inflammation induced in this way affects the whole body and increases the risk of inflammatory diseases of the skin, alopecia, exacerbation of allergic dermatitis, stroke, inflammatory diseases of the brain (such as alzheimer's disease), respiratory diseases and cardiovascular diseases.
At present, the demand for materials having anti-inflammatory and antioxidant functions, which have skin-protecting effects on inflammatory reactions and oxidative stress caused by fine dust and the like, is rapidly increasing, and thus, there is a need to obtain new materials having good effects and little side effects from natural materials having safety.

Detailed Description
Hereinafter, specific embodiments of the present invention will be described in detail so that those skilled in the art can easily practice the present invention. The invention may, however, be embodied in several different forms and is not limited to the embodiments described.
In one aspect, the present invention relates to an antioxidant or anti-inflammatory food composition comprising a mixed extract of myrtle and sparassis crispa as an active ingredient.
The antioxidant or anti-inflammatory food composition of the present invention comprises active ingredients of a mixed extract of myrtle and sparassis crispa.
In the present invention, "myrtle (Backhausia citriodora)" mainly refers to shrubs growing in forests in the tropical zone of Queensland, Australia. The leaves of lemon myrtle, which have a lemon flavor, are the most widely used flavoring material in australia, and recently are used as a raw material or a flavoring agent for herbal tea, candies, beverages, nutritional supplements, and the like. In addition, the lemon myrtle essential oil has the strongest fragrance in various oils with lemon fragrance, has the longest fragrance retention time, and is mainly used for manufacturing perfumed soaps, lip balms or perfumes. The lemon aroma of lemon myrtle originates from the citral component, and unlike lemon which contains about 3 to 10% citral, lemon myrtle contains about 90% citral and therefore gives off a stronger taste or aroma than lemon, but reportedly, it is also more astringent and bitter. Citral is a monoterpene aldehyde component known to be insoluble in water, mainly soluble in alcohols or ethers.
In the present invention, "Sparassis crispa" is a mushroom belonging to Aphyllophorales (Aphyllophorales) and Sparassidaceae (Sparassidaceae), is distributed in Korea, Japan, China, Europe, North America, Australia, etc., is longer than near the root of coniferous trees or on stumps of trees for 8 to 9 months, has a fruiting body 10 to 25cm high in flesh quality, has a large number of branches on a thick handle at the bottom, has a wavy upper flat edge, is in the shape of white flower cabbage, emits a light fragrance, has good chewing feeling, and has an edible value. In addition, the content of beta-1, 3-D-glucan is significantly higher than that of other mushrooms, and is known to have various physiological activities. That is, it is known to have anticancer and anti-angiogenic effects, antitumor effects, antibacterial and antifungal effects, and antiallergic effects, even on diabetes. It is also involved in cytokine production in mice and is effective in acute liver injury.
In the present invention, "extract" means an extract obtained by an extraction treatment, a diluted or concentrated solution of the extract, a dried product obtained by drying the extract, a preparation or purified product of the extract, or a mixture thereof; it includes all formulations of extracts that can be formed using the extract itself and the extract.
In the present invention, useful components in the dried plant of the extract are not destroyed. This can be carried out by a known method, for example, by natural drying in the shade. In addition, useful components of plants can be sufficiently extracted in a subsequent extraction process by breaking the walls or pulverizing into powder. The drying, pulverizing or wall breaking process may be performed in reverse order or repeatedly as necessary.
The extract can be prepared by conventional preparation method of plant extract, specifically solvent extraction, water immersion extraction, cold immersion extraction, warm immersion extraction or ultrasonic extraction, and existing extraction device, ultrasonic pulverizing extractor, fractionator, etc. can be used.
The extraction solvent of the extract can be water or organic solvent. The organic solvent may be a polar solvent, a non-polar solvent or a mixture thereof, such as alcohol, aqueous alcohol solution, hexane, dichloromethane, acetone, ethyl acetate, diethyl ether, chloroform or a mixture thereof. The alcohol is C1-C5 alcohol, such as methanol, ethanol, propanol, butanol, isopropanol, etc. Further, the alcohol aqueous solution can be obtained by diluting alcohol in water to 50 to 99.9% (v/v).
Further, the extract is extracted with a solvent, and then subjected to a fractional distillation process using any one solvent selected from the group consisting of hexane, dichloromethane, acetone, ethyl acetate, diethyl ether, chloroform, water and a mixture thereof. The fractionation process may be prepared using two or more solvents, and each solvent fraction may be used sequentially or in a mixture depending on the polarity of the solvent.
The prepared extract or the fraction obtained by the fractional distillation process may then be filtered or concentrated or dried to remove the solvent, and may be filtered, concentrated and dried at the same time. Specifically, for example, filter paper or a reduced pressure filter may be used for filtration, concentration may be performed under reduced pressure using a reduced pressure concentrator such as a rotary evaporator, and drying may be performed by a freeze-drying method.
In the present invention, the "mixed extract" refers to an extract prepared by extracting Cimyrtus citriodora and Sparassis crispa, and may be prepared by extracting Cimyrtus citriodora and Sparassis crispa respectively and then mixing them, or may be prepared by extracting Cimyrtus citriodora and Sparassis crispa respectively and then mixing them.
The lemon myrtle may be at least one selected from the group consisting of stem, leaf, root, flower and fruit, preferably lemon myrtle leaf.
In one embodiment of the invention, dried myrtle and sparassis crispa are mixed and then extracted under pressure at 80-120 ℃ for 1-5 hours by using distilled water as a solvent.
Therefore, the mixed extract can be a hot water extract of myrtle and sparassis crispa, and specifically can be a hot water extract at 90-110 ℃, and the extraction time is 2-4 h.
In one embodiment of the present invention, the extract is prepared by mixing myrtle and sparassis crispa in a weight ratio of 1: 0.1-10, and the cytotoxicity of the extract is analyzed according to the mixing ratio of myrtle and sparassis crispa, and it is shown that the extract prepared by mixing myrtle and sparassis crispa in a weight ratio of 1:1 (example 1) does not show cytotoxicity.
Therefore, in the invention, the mixed extract can be prepared by mixing and extracting the myrtle and the sparassis crispa in a weight ratio of 1: 0.1-10, specifically, the weight ratio of the myrtle to the sparassis crispa is 1: 0.5-5, preferably 1:1, and extracting with hot water at 90-110 ℃.
In one example of the present invention, it was demonstrated that the concentration of a mixed extract of myrtle and sparassis crispa (example 1, LB) was positively correlated with an increase in DPPH clearance activity. In order to analyze the antioxidant effect, after LPS induced brain inflammation in mice, a mixed extract (LB) of myrtle and sparassis crispa was administered to analyze the change in the production of lipid peroxide (MDA), which is an index of oxidative damage, and it was shown that LPS increased the production of MDA in the brains of experimental animals by about 170%, indicating that LPS induced oxidative damage. It was confirmed that the amount of MDA production increased by LPS was statistically significantly reduced when a high dose (1000mg/kg) of a mixed extract (LB) of Myrtus citriodora and Sparassis crispa was injected.
That is, it was confirmed that the mixed extract of myrtle lemon and sparassis crispa has DPPH scavenging activity and has excellent antioxidant effect by inhibiting lipid peroxide (MDA) caused by oxidative damage, and the extract can be used as an antioxidant composition.
In the present invention, "antioxidation" means protection of cells from oxidative stress, specifically, inhibition of the production of active oxygen or inhibition of the production of lipid peroxide.
In another example of the present invention, anti-inflammatory effects of myrtle and sparassis crispa (LB) were analyzed, and after inducing brain inflammation in mice using LPS, the increase degree of inflammation-associated cells, namely microglia (microglia) and astrocyte (astrocyte), in brain tissues of mice was analyzed after oral administration of a mixed extract of myrtle and sparassis crispa (LB) for 7 days. The results of the analysis showed that LPS induced an increase in GFAP-positive cells (an astrocyte marker) and Iba-1-positive cells (a microglia marker) in the brains of the experimental animals. It was confirmed that when a mixed extract (LB) of myrtle and sparassis crispa was orally taken, the increase of astrocytes (GFAP-positive cells) and microglia (Iba-1-positive cells) induced by LPS was significantly reduced.
That is, it was confirmed that the mixed extract of myrtle and sparassis crispa has an anti-inflammatory effect, and the mixed extract of myrtle and sparassis crispa of the present invention can be used as an anti-inflammatory composition.
In the present invention, "anti-inflammatory" refers to inhibiting or preventing the occurrence of inflammation, or protecting cells from inflammatory damage.
In the present invention, inflammation may be caused by, but is not limited to, microbial infection, exposure to sand or fine dust, exposure to chemicals, or oxidative stress.
