Described Antrodia Camphorata extract adopts following methods preparation
Antrodia Camphorata sporophore is adopted water and alcohol steep respectively, obtains flooding extract and alcohol steep thing by after water extract and alcohol extract respectively drying, and both are merged as Antrodia Camphorata extract.
Described Antrodia Camphorata extract preparation technology be
1) after the Antrodia Camphorata sporophore of drying being mixed according to the ratio of w/v 1:10 ~ 20 with water at 70 ~ 95 DEG C lixiviate 30-60min, and extracting solution concentrate drying is obtained flooding extract,
2) by step 1) in Antrodia Camphorata sporophore after flooding, add and be equivalent to raw material Antrodia Camphorata sporophore weight 5-8 ethanol doubly, be heated to backflow lixiviate 60 ~ 90nin, filter and obtain filtrate,
3) will through step 2) in the Antrodia Camphorata sporophore of alcohol steep, then add and be equivalent to raw material Antrodia Camphorata sporophore weight 5-8 ethanol doubly, be heated to backflow lixiviate 60 ~ 90nin, filter and obtain filtrate
4) by step 2), 3) filtrate that obtains merges concentrate drying and obtains alcohol steep thing, merge alcohol steep thing and flooding extract as Antrodia Camphorata extract.
Antrodia Camphorata extract emulsifiable paste provided by the invention, adopts following methods preparation
1) preparation of aqueous phase, after first soybean phospholipid being dissolved in ethanol, add the Antrodia Camphorata extract of recipe quantity, after abundant mixing, spraying dry obtains the composite micro-powder of Antrodia Camphorata extract and soybean phospholipid, composite micro-powder, wetting agent, antioxidant, pH buffer agent are added in the water of recipe quantity and is heated to 60-90 DEG C and dissolves dispersion, obtain aqueous phase.
2) preparation of oil phase, the component as oil-phase component of getting recipe quantity is heated to melt (60 DEG C ~ 90 DEG C), adds antibiotic antiseptic and is stirred to evenly and get final product;
3) preparation of Antrodia Camphorata extract emulsifiable paste
By heated aqueous to after 60 DEG C ~ 90 DEG C, then the oil phase being heated to 60 ~ 90 DEG C is slowly joined in aqueous phase, stir while adding and evenly namely obtain Antrodia Camphorata extract emulsifiable paste to condensation.
Described in the present invention, percentage ratio is all weight percentage.
We find under study for action, soybean phospholipid and Antrodia Camphorata compound extract is adopted to be the emulsifiable paste of active component, the phototoxicity of remarkable reduction Antrodia Camphorata extract used time outside, and the safety in utilization of Antrodia Camphorata extract emulsifiable paste can be improved, overcome Antrodia Camphorata extract outside the used time due to its phototoxicity bring to use restriction, the ability of its anti-skin photoage can be improved again simultaneously, sun-proof or sun-proof secondary purpose can be applied.Find only have soybean phospholipid can realize this effect additionally by contrast, use merely Antrodia Camphorata extract or jointly use then without this effect with conventional other phospholipid such as Ovum Gallus domesticus Flavus lecithin.
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
The preparation of Antrodia Camphorata extract

Pharmacological Examples 1
1 material
1.1 organize hydroxyproline test kit, build up Bioengineering Research Institute purchased from Nanjing.
1.2 animal Kunming mouses, female Mus, body weight 20-25g, 7-8 week age, provided by Shanghai Univ. of Traditional Chinese Medicine's Experimental Animal Center, often organize 10, grouping with administration as following table:
Remarks: in experimental group 5,6, replace composite micro-powder for the preparation of aqueous phase after Antrodia Camphorata extract is added ethanol, directly add soybean phospholipid powder when preparing aqueous phase in embodiment 7.Antrodia Camphorata extract and soybean phospholipid is not added during the substrate preparation that normal group and model group use.
2 methods
Mouse back skin is shaved only by 2.1 animal groupings and model preparation electric hair clipper, about 2cm × 2cm, baring skin, random point 3 groups.Normal group, skin smears embodiment 3 emulsifiable paste matrix, without other any process every day; 2nd group is model group, and skin smears 1%8-methoxypsoralen (8-MOP) 1 time every day, after 1.5-2h, gives 190 μ w/cm
2uVA irradiate, cumulative exposure 138h (integrated intensity 95J/cm
2), irradiate and terminate bark fetching skin in rear 24h; It is Experimental agents that each test group of animals skin smears concentration every day, repastes and smears 1%8-MOP, after 1.5-2h, give 190 μ w/cm after slightly dry
2uVA irradiate, cumulative exposure 138h (integrated intensity 95J/cm
2), irradiate and terminate bark fetching skin in rear 24h; To obtaining skin histology, carry out hydroxyproline content mensuration, and according to the form below carries out phototoxicity scoring to laboratory animal
2.2 organize hydroxyproline content to measure assay method operates according to test kit, detects histone simultaneously, calculates hydroxyproline/total protein ratio, t check analysis result.Result is as following table:
Testing result as following table (
n=10)
In prior art, the content of hydroxyproline is often used to characterize the degree of aging of skin, experimental result shows, the experimental group 1-2 of the emulsifiable paste adopting the embodiment of the present invention to prepare, hydroxyproline in the skin of laboratory animal/total protein ratio higher and closer to the normal group as negative control, and as the model group of positive control, hydroxyproline/total protein ratio occurs obviously to decline.Illustrate that Antrodia Camphorata extract emulsifiable paste provided by the invention significantly can suppress the photoaging of skin, and phototoxicity scoring shows that the animal of experimental group 1-2 average score compared with model group increases not obvious, and do not adopt the experimental group 3-6 of soybean phospholipid and Antrodia Camphorata compound extract, although hydroxyproline/total protein scale increases compared with model group, but phototoxicity scoring shows that its medicine used all shows stronger phototoxicity under ultraviolet radiation, to illustrate under the condition that illumination is strong and inapplicable, and experimental group 7 shows, simple use soybean phospholipid, hydroxyproline/total protein ratio and phototoxicity two indexs of marking all are had no significant effect.
