The antioxidant capacity of ultraviolet-radiated skin can be improved; removal of oxygen free radicals can be accelerated; amino acid metabolism of skin tissues after ultraviolet radiation is adjusted; and the content of skin collagen is increased, s that the anti-ultraviolet radiation sun cream plays a protecting role in the ultraviolet-radiated skin, and skin photoaging is delayed.
Description
Technical field
The invention belongs to technical field of skin care, in particular to a kind of sunscreen cream of ultra-violet radiation resisting.
Background technology
Along with ozone layer is day by day thinning, the ultraviolet arriving ground is on the increase.The uitraviolet intensity contained in sunlight is very high, summer direct sunlight skin, ultraviolet easy penetrating skin surface, ultraviolet radiation can not only produce melanin, makes skin darkening, makes the possibility of skin ageing in addition, after skin accepts ultraviolet overexposure, can lesional epidermis cell.The damage great majority that sunlight causes are that the ultraviolet radiation being 200 to 400nm by wavelength causes.The UVC that its medium wavelength is less than 290nm is absorbed by ozone layer substantially, cannot arrive ground; Wave-length coverage is that the UVB of 290 to 320nm can cause burning and cutaneous pigmentation; Wave-length coverage is that the UVA of 320 to 400nm can cause slightly burning with tanned.The sun-prevention component used in usual cosmetics, as nano titanium oxide, zinc oxide, benzophenone etc., owing to there is such as skin irritation, problem such as blocking pore, heliosensitivity etc., has strict consumption restriction.The sunscreen of natural botanical source, because of its wide spectrum, safe sun-proof result, enjoys consumers.
CN103588616A discloses a kind of Selaginella pulvinata extract and its preparation method and application, conduct in-depth research for Selaginella pulvinata extract, use multiple column chromatography separation technology and half preparative high-performance liquid chromatographic separation method, extraction and isolation has 9 to a class, the compound (DZJB1-13) of the new framing structure of 9-diphenyl-1-(phenylacetylene base)-9H-fluorenes, and disclose the activity that these compounds significantly can suppress 4 type phosphodiesterases (PDE4), can be used for preparation PDE4 inhibitor, treatment asthma, chronic obstructive pneumonia, inflammation etc.At present, the biological activity after still not having this compounds external of bibliographical information in the skin injury that causes of control ultraviolet.
Summary of the invention
The object of the invention is to, by studying the biological activity of native compound monomer, provide a kind of sunscreen cream of ultra-violet radiation resisting.This sunscreen cream is with (7-acetoxyl group-2-(acetoxy-methyl)-1-((4-acetyloxy phenyl) acetenyl)-9H-fluorenes-9,9-bis-replaces) two (4,1-phenylene) diacetate esters (DZJB-13) or derivatives thereof is active component, Mice Photoaging model caused by ultraviolet is had to the protective action of highly significant, can be developed into the sunscreen cream of ultra-violet radiation resisting.
In order to realize object of the present invention, inventor is studied and persistent exploration by a large amount of animal experiment, finally obtains following technical scheme:
A kind of sunscreen cream of ultra-violet radiation resisting, this sunscreen cream is prepared from by active component and adjuvant, described active component comprises (7-acetoxyl group-2-(acetoxy-methyl)-1-((4-acetyloxy phenyl) acetenyl)-9H-fluorenes-9,9-bis-replaces) two (4,1-phenylene) diacetate esters or derivatives thereof.
In addition, in embodiment preferred for this invention, active component in the sunscreen cream of ultra-violet radiation resisting described above is by (7-acetoxyl group-2-(acetoxy-methyl)-1-((4-acetyloxy phenyl) acetenyl)-9H-fluorenes-9,9-bis-replaces) two (4,1-phenylene) diacetate esters is prepared from as sole component.
The sunscreen cream of ultra-violet radiation resisting of the present invention, is the common process that those skilled in the art utilize this area, the basis not spending creative work can be prepared from.Especially, sunscreen cream of the present invention can adopt following processing step to prepare:
(1) get glycerol to mix with appropriate distilled water, when being heated to about 70 DEG C, adding sodium sulfite, ethyl hydroxybenzoate, sodium lauryl sulphate, be stirred to dissolving, make aqueous phase.
(2) get methyl-silicone oil, liquid paraffin, Cera Flava, 1-hexadecanol, glyceryl monostearate, stearic acid, heat fused, during when the temperature to about 70 DEG C, add vitamin E, DZJB-13 successively, make oil phase.
(3) oil phase is slowly added in aqueous phase under constantly stirring, make emulsifying, be stirred to solidifying, obtain faint yellow oil-in-water type cream.
UVA and UVB wave band in ultraviolet is the material impact factor that human body skin produces photoaging, and ultraviolet radiation can increase the generation of oxygen-derived free radicals, causes and organizes oxidation resistance to reduce, and finally causes skin tissue aging, and this becomes the major reason of skin aging.Free radical can bring out biomembrane unsaturated fatty acid---and arachidonic acid peroxidating, generate the metabolite of the lipid peroxide such as MDA, the rising of its content can reflect the increase of skin injury degree.The antioxidant activity enzyme materials such as SOD, CAT, GSH-Px can the generation of regulation of skin free radical, removes unnecessary oxygen-derived free radicals, avoids too early skin aging.Collagen fiber are the important component in corium, are mainly collagen protein, and its content obviously can decline with the growth at age, thus cause skin elasticity to decline, cutis laxa, therefore, and the degree of the change reflection skin aging of collagen content.Hyp is the aminoacid of intradermal stable content, and its content directly reflects the changes of contents of intradermal collagen fiber, thus the degree of prompting corium aging.In skin histology, Hyp changes of contents is the sensitive indicator judging skin aging degree.
The present inventor is found by the Mice Photoaging model investigation caused by ultraviolet, after ultraviolet radiation, model control group compares with Normal group, two groups of skin histology SOD, GSH-Px, CAT, MDA levels and Hyp content all have pole significant difference (
p< 0.01); Compare with model control group, DZJB-13 group skin histology SOD, GSH-Px, CAT level and Hyp content significantly decline (
p< 0.05 or
p< 0.01), MDA level significantly raises (
p< 0. 01).This imply that DZJB-13 can improve the oxidation resistance of ultraviolet radiation skin, accelerate scavenging activated oxygen, and skin histology amino acid metabolism after regulating ultraviolet radiation, increase the content of skin collagen, thus protective action is played to ultraviolet radiation hairless mouse skin, delaying skin photoaging.Therefore, the present invention also provides a kind of compound novelty teabag, that is: (7-acetoxyl group-2-(acetoxy-methyl)-1-((4-acetyloxy phenyl) acetenyl)-9H-fluorenes-9,9-bis-replaces) two application of (4,1-phenylene) diacetate esters or derivatives thereof in the skin care item preparing ultra-violet radiation resisting.
Compared with prior art, the invention provides (7-acetoxyl group-2-(acetoxy-methyl)-1-((4-acetyloxy phenyl) acetenyl)-9H-fluorenes-9, 9-bis-replaces) two (4, 1-phenylene) diacetate esters and derivant thereof be for the preparation of the sunscreen cream of ultra-violet radiation resisting, this sunscreen cream can improve the oxidation resistance of ultraviolet radiation skin, accelerate scavenging activated oxygen, and skin histology amino acid metabolism after regulating ultraviolet radiation, increase the content of skin collagen, thus protective action is played to ultraviolet radiation skin, delaying skin photoaging.
