Summary of the invention
Technical problem to be solved by this invention provides a kind of natural Chinese medicine composition to the high and effective whitening function of human safety that is derived from.
Another technical problem to be solved by this invention provides the application of above-mentioned Chinese medicine composition.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
A kind of Chinese medicine composition of Pear Power function is characterized in that it comprises the component of following percentage by weight:
Radix Scutellariae extract 10~50%
Rhizoma Polygoni Cuspidati extract 10~50%
Cortex Moutan extract 10~50%
Above-mentioned Chinese medicine extract can obtain by conventional solvent extraction method, for example can with above-mentioned plant rhizome etc. with extract that solvent soaks or reflux after, filter, concentrate and obtain.Unqualified about the extraction solvent that uses among the present invention, can use so long as be generally used for the solvent of plant extract, for example water, methanol, ethanol, aqueous alcohols, acetone etc.Also be not particularly limited for extracting operation, can only use solvent slightly to carry, or carry out further separation and purification treatment, for example the extracting solution former state that above-mentioned solvent extraction is obtained or concentrate after extracting solution remove impurity by resin.
The application of above-mentioned Chinese medicine composition on the preparation skin-whitening agents.
With respect to the total amount of external agent, the use level of above-mentioned plant extract in the skin-whitening agents of the present invention in dry thing, is 0.05~20% (w/w), and preferable amount is 0.5~5% (w/w).
In Dermatologic preparation for beautifying of the present invention, except that above-mentioned essential composition, can suitably cooperate the composition that in cosmetics, uses usually as required, for example, matrix components such as other whitening agent, wetting agent, antioxidant, surfactant, alcohols, water.
The dosage form of skin-whitening agents is not particularly limited, and can be solution, suspension, emulsion, paste, gel, milk, skin care liquid, powder, fancy soap, oil, dry powder, foundation emulsion, wet-milling or spray.
Beneficial effect: the Chinese medicine composition of Pear Power function of the present invention has restraint of tyrosinase, free radical resisting and anti-ultraviolet effect, can effectively suppress melanin and generate, desalination pigmentation, senile plaque, freckle etc.Compare with other whitening agents, said composition can suppress melanic synthetic from different approach comprehensively, has excellent whitening effect, and simultaneously, said composition does not contain the chemosynthesis material, has no side effect, and skin irritation is little, stable in properties.Except that whitening effect, because said composition contains the plurality of Chinese active component, have functions such as blood circulation promoting and blood stasis dispelling, antiinflammatory be antibacterial, can promote the metabolism of skin, the nutrition that improves skin makes skin pure white naturally tender with healthy.
The specific embodiment:
The present invention will be described in more detail to enumerate embodiment below, but technical scope of the present invention is not limited by these embodiment.Below all proportional quantities all by weight percentage.
Embodiment 1: experimental technique and whitening effect evaluation
1, sample preparation
The Chinese medicine crude drug spends the night in oven drying, pulverizes the back and crosses 40 mesh sieves, adds 10 times 50% ethanol, heating and refluxing extraction 3 times, each 1 hour.Merge extractive liquid,, sucking filtration while hot.Decompression filtrate recycling ethanol is placed.The centrifugal precipitation of removing, supernatant is collected 70% ethanol elution by D101 macroporous resin eluting, and reduced vacuum concentrates, and obtains Chinese medicine extract.Extract is dissolved in the dimethyl sulfoxide, is made into concentration and is 1% solution, carry out following experiment.
2, the mensuration of free radical scavenging effect
Diphenyl picryl phenylhydrazine (DPPH) the solution 2mL that gets extracts of Chinese herbal medicine 2mL and concentration and be 100umol/L successively adds in the same tool plug test tube, shakes up; Left standstill working sample absorbance under the 517nm wavelength under the room temperature 30 minutes.
Suppression ratio: k%=[1-(A
i-A
j)/A
c] * 100%
A
i: the absorbance of 2ml DPPH solution+2ml extracting solution
A
j: the absorbance of 2ml extracting solution+2ml solvent
A
c: the absorbance of 2ml DPPH solution+2ml solvent
3, anti-ultraviolet property is measured
In 280~400nm wave-length coverage, scan every 10nm, determine the light transmittance of Chinese medicine extraction liquid under each wavelength, calculate the average absorption rate of wave-length coverage.
4, suppress tryrosinase vitality test in the mouse melanin cell
The B16 melanocyte is inoculated in 96 orifice plates, every hole 100uL, put in the incubator cultivate educate 24h after, add Chinese medicine extraction liquid.Behind the drug effect 3d, abandoning supernatant, with pH 6.8 poly butylene succinates (PBS) flushing twice, every hole adds the PBS that 90uL contains 1% (volume fraction) Triton X-100.Ultrasonication in the ice bath, every hole add the L-DOPA (L-dopa) of 10uL 10mmoL/L, hatch 60min for 37 ℃, and in 475nm place colorimetric, each hole absorbance is surveyed in the blank well zeroing.
Suppression ratio=(1-medicine group mean light absorbency value ÷ matched group mean light absorbency value) * 100%.
5, suppress melanocyte synthetic test in the mouse melanin cell
Will be from the B16 melanoma cells of mice with 1 * 10
5The density of individual/mL is inoculated in culture dish, at 37 ℃, 5%CO
2Condition under cultivated 2 days.Abandon supernatant, add Chinese medicine extraction liquid, behind the drug effect 3d, abandon supernatant, the PBS washing, every hole adds 0.5mL trypsin digestion cell 3min, and every hole adds 2ml and keeps liquid termination digestion.Behind the piping and druming mixing, every kind of concentration is taken out 0.5mL and is done the cell counting.All the other cell suspension are abandoned supernatant with the centrifugal 5min of 2500r/min, add NaOH solution in precipitation, and heating makes the melanin dissolving, select the 490nm wavelength to survey absorbance on enzyme-linked immunosorbent assay instrument.
Melanin synthesizes suppression ratio=[1-(medicine hole absorbance ÷ medicine porocyte density) ÷ (control wells absorbance ÷ control wells cell density)] * 100%
