Embodiment 1

[0028] Embodiment 1, the preparation of Brassica chinensis ethanol extract

[0029] Take the root of Baizicai as raw material, wash it, crush it into a powder with a particle size of 40 mesh, add 80% ethanol solution of 8 times the total amount of the powder, heat and reflux for extraction twice, each time for 1.5h, and the extraction temperature is 70°C , Filtrate, combine the filtrates, remove ethanol under reduced pressure, and concentrate.

[0030] According to the above method, 75% and 65% ethanol solutions are used for extraction to obtain 75% ethanol extract and 65% ethanol extract respectively.

Embodiment 2

[0031] Embodiment two, the preparation of water extract of Chinese cabbage

[0032] Take the root of Baizicai as raw material, wash it, crush it into a powder with a particle size of 40 mesh, add 8 times the total amount of the coarse powder, and extract it twice with hot water at a temperature of 80°C, 6 hours each time, filter, combine the filtrate, and concentrate , that is.

Embodiment 3

[0033] Example 3. Comparison of Whitening Activity and Stimulus of Alcoholic Extract and Water Extract of Brassica chinensis

[0034] 3.1 Comparison of whitening activity

[0035] Each group of samples was diluted with disodium hydrogen phosphate-citric acid buffer solution (pH6.8, 0.05mol / L) to obtain multi-level concentration samples, and each concentration sample was taken in a glass test tube, and tyrosinase solution was added respectively; at 30°C After reacting in a water bath for 10 minutes, add levodopa solution to each group of glass test tubes in turn, then react in a water bath at 30°C for 10 minutes, and measure the OD value at 475 nm. The experimental system is shown in Table 1.

[0036]

[0037] In the formula: T is the absorbance value of the sample tube, that is, the absorbance value of the solution after the sample reacts with tyrosinase; T 0 is the background absorbance value of the sample; C is the average value of the three times of the absorbance value...

Abstract

The invention relates to a non-irritant composition with whitening and moisturizing functions and a preparation method thereof. The composition contains gynura divaricata active matter and gypenosideas effective components. According to the invention, xylaria nigripes is adopted to ferment a gynura divaricata alcohol extract to obtain the active matter with a relatively high inhibition effect ontyrosinase, and meanwhile, the problem of skin irritation caused by the gynura divaricata alcohol extract is solved, so that the active matter can be used as a whitening active ingredient to be applied to preparation of cosmetics. Besides, the invention finds the possibility that the gypenoside and the active matter have a synergistic effect after being combined; and when the gypenoside and the active matter are combined to act, the whitening activity of the composition is improved, the irritation of the composition is further reduced, and the composition can be applied to preparation of non-irritant whitening products.
