Close object.
The effect of cleawhite over-night essences of present invention composition containing compound skin-whitening, is assessed
1, tyrosinase inhibition rate
Participating in B16 cell, there are mainly three types of enzymes:Tyrosinase, dopachrome interconvertible enzyme and dihydroxy indole carboxylic acid oxygen
Change enzyme.Tyrosinase category oxidoreducing enzyme, is the major rate-limiting enzyme of B16 cell, and tyrosinase can with its substrate l-tyrosine
Catalysis reaction occurs.
After being added to the reagent of tyrosinase activity inhibiting effect in experimental system, catalysis reaction can be generated
Inhibiting effect, by the light absorption value before and after measurement addition reagent at 475nm, to evaluate inhibition of the reagent to tyrosinase activity
Rate.Under different tested concentration, cleawhite over-night essences tyrosinase inhibition rate experimental result such as 3 institute of table of the composition containing compound skin-whitening
Show:
Table 3
As shown in Table 3, the cleawhite over-night essences of the composition containing compound skin-whitening has good tyrosinase inhibition rate, when tested
When a concentration of 1.0%, the cleawhite over-night essences tyrosinase inhibition rate of present invention composition containing compound skin-whitening reaches 70% or so, table
The cleawhite over-night essences of bright present invention composition containing compound skin-whitening has good tyrosinase inhibition rate;And in identical concentration
Under, the inhibiting rate of the cleawhite over-night essences tyrosinase of the composition containing compound skin-whitening is higher than the competing product of commercially available whitening.
2, melanocyte is tested
The Essence of composition containing compound skin-whitening is inquired into the proliferation of melanocyte and the influence of whitening function.Utilize B16
Melanoma cells measure influence of the Essence to melanocyte proliferation function, and to melanocyte synthesis of melanin
Influence.
(1) measurement (mtt assay) of cell proliferation rate
Murine melanoma B16 cells are cultivated, wait for that cell growth to logarithmic phase, is digested with 0.25% pancreatin, adjusts cell
A concentration of 5 × 104A/mL is inoculated in 96 orifice plates, per 100 μ L of hole.It is placed in incubator after cultivating for 24 hours, abandons supernatant, add
Add pastille culture medium, three concentration groups of each sample.Each concentration sets 3 multiple holes, and control group is not added with drug, instead accordingly
Solvent.After being incubated 72h, supernatant is abandoned after MTT solution 20 the μ L, 4h of 5g/L is added per hole, 100 μ of cell pyrolysis liquid is added per hole
L continues overnight incubation, each hole absorbance value, wavelength 570nm is detected in microplate reader.
Cell proliferation inhibition rate %=(1- medicine groups average absorbance value/control group average absorbance value) × 100
(2) measurement of B16 cell inhibiting rate
By B16 melanocytes with 20 × 104The density of a/mL is inoculated in 96 orifice plates.Per hole 1mL, after being incubated for 24 hours,
Supernatant is abandoned, adds drug to be measured (sample effect concentration is with aforementioned), after drug effect 72h, abandons supernatant, PBS washings, per hole
The 500 μ L of 1mo l/LNaOH solution containing 10%DMSO, concussion 5mi n is added.Measure each hole light absorption value under 490nm.
B16 cell inhibiting rate %=[1- (drug hole 490nm absorbance values/drug hole 570nm absorbances)/(control
Hole 490nm absorbance values/control wells 570nm absorbances)] × 100
After the cleawhite over-night essences tested material of various concentration composition containing compound skin-whitening is added, sample is to melanocyte black
Element synthesis inhibiting rate and cell proliferation inhibition rate experimental result are as shown in table 4:
The cleawhite over-night essences sample of 4 various concentration composition containing compound skin-whitening of table is to the proliferation inhibition rate of B16 cells and black
Pigment synthesis inhibiting rate
Conclusion:After the tested material of various concentration is added, the cleawhite over-night essences sample of the composition containing compound skin-whitening has preferably
Inhibition melanocyte synthesis of melanin effect, in tested concentration range (0.5-2.0%), B16 cell inhibiting rate
In 33-41%, show that the cleawhite over-night essences of the composition of the invention containing compound skin-whitening has good white-skinned face function, same concentrations item
Under part, the cleawhite over-night essences B16 cell inhibiting rate of the composition containing compound skin-whitening is higher than commercially available competing product, and cell proliferation
It influences to be higher than commercially available competing product.
3, crowd's investigation on probation
For the practical effect of test product, people has been carried out respectively to sample made from Essence 1-5 and comparative example 1-4
Group's investigation on probation distributes sample to the volunteer (wherein women 385) at 500 ages 28-42 Sui, health, life rule
Rule, no skin disease, volunteer are divided into 10 groups at random, and one of which is commercial product cleawhite over-night essences.Volunteer cleans face
It after skin, dries, appropriate Essence is applied to left side face with hand, right side face does not smear, as skin whitener test comparison
Area, tested period face do not smear other cosmetics or drug, and continuous use checks using effect in 30 days, and fills in investigation and ask
Volume.
It is classified the standard of judgement:
Significantly effectively:Opposite right side face, test block color spot problem are completely resolved, and skin smooth is for example new, the white and moist pool of jade-like stone.
Effectively:Opposite right side face, test block color spot is obviously thin out, forms color spot soon or even can completely disappear, skin
Skin becomes pale.
In vain:Opposite right side face, test block color spot do not change without significant change or intensification, the colour of skin.

Conclusion:In the cleawhite over-night essences sample of the composition containing compound skin-whitening, it is (Caesalpinia spinosaKuntze fruit, short to be added to whole components
The hard English walnut seed of cut tobacco orchid root, Bai Er, climbing entada stem rattan) Essence 1-5 effects (significantly effectively >=23) it is more independent than only adding
The effect (significantly effectively≤1) of the comparative example 1-4 of ingredient will be got well, and only the effect of the comparative example 1-4 of addition separate constituent is simultaneously
Not significantly, the results showed that each ingredient has mutually association in skin whitening and dispelling stain etc. in the compound skin-whitening composition
Effect together simultaneously obtains preferable effect.
By Essence 1-5 with commercial product (significantly effective 12) comparison it is found that the whitening effect of the present invention is more preferable.
It is learnt through questionnaire, makes have essence liquid product of the present invention, mild non-stimulated, skin sense is fine.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
It encloses and is defined, under the premise of not departing from design spirit of the present invention, technical side of the those of ordinary skill in the art to the present invention
The various modifications and improvement that case is made should all be fallen into the protection domain of claims of the present invention determination.
