Embodiment 1

[0034] Embodiment 1, preparation and detection of Rhodiola rosea fermented puree cosmetics

[0035] The concentration of fermentation bacteria in the expansion culture medium was 10 5 -10 8 Inoculate 20mL of CFU / ml fermented bacteria liquid into 50 mesh 10g rhodiola root powder and 200g water, and ferment in a shaker at 28°C for 48 hours, then autoclave the obtained fermentation liquid at 115°C for 20min Autoclave to inactivate the bacteria, centrifuge the sterilized fermented liquid for 20 min at 12,000 r / min and a centrifugal radius of 9 cm, collect the supernatant, which is the rhodiola fermented puree cosmetic provided by the present invention.

[0036] The appearance of the Rhodiola rosea fermented puree cosmetic prepared in this example is viscous liquid, and the color is light pink to brownish red. The pH value is 5.2-6.8, the viscosity is 200-500cP, the soluble solid content is 1.5-5.0%, the total number of colonies is less than 50CFU / ml, and no pathogenic bacteria a...

Embodiment 2

[0039] Embodiment 2, the antioxidation effect analysis of Rhodiola rosea fermented protoplasm

[0040] DPPH is an early synthesized organic free radical, which is often used to evaluate the hydrogen-donating ability of antioxidants. It is very stable in organic solvents, has a purple color, and has a characteristic absorption peak at , when it encounters a free radical scavenger , the lone pair of electrons of DPPH is paired to make it fade, that is, the light absorption value at the maximum absorption wavelength becomes smaller. Therefore, the scavenging effect of the sample on DPPH free radicals can be evaluated by measuring the change of the absorbance value.

[0041] The specific experimental steps of the DPPH free radical scavenging experiment are as follows:

[0042] (1) Take an equal volume (usually 3mL) of the solution to be tested and 2×10 -4 mol / L DPPH solution mixed (A 1 Tube);

[0043] (2) Take an equal volume of absolute ethanol (the solvent for the analyte) a...

Embodiment 3

[0049] Embodiment 3, the whitening efficacy analysis of Rhodiola rosea fermented protoplasm

[0050] Tyrosinase is the key enzyme of melanin production, it controls the formation process of melanin, and its activity plays a major role in the deposition of pigment. Many whitening and freckle-removing products currently on the market achieve whitening effects by inhibiting tyrosinase, so the strength of the inhibitory effect on tyrosinase is the main indicator for evaluating whitening cosmetics.

[0051] Evaluate the whitening function of the sample by measuring the impact of the sample on tyrosinase, the specific method is as follows:

[0052] Configure the solution according to Table 1:

Abstract

The invention discloses a Rhodiola rosea fermented puree cosmetic and a preparation method thereof. The Rhodiola rosea fermented raw puree cosmetic has an active ingredient of the supernatant obtained by sterilizing and centrifuging the fermented liquid obtained from the initial system fermented by mixing rhodiola root powder, water and fermenting bacteria. The fermenting bacteria is yeast. The invention adopts the yeast to ferment the whole plant of rhodiola root, retains all functional components and activities of the plant, and avoids the loss of active components caused by the extraction method. No organic reagents are added during extraction, the fermentation temperature and fermentation pH are mild, the structure of plant active ingredients is not destroyed, and the natural activity of plants is maintained. No fragrance and other harmful chemical components are added to the fermentation puree to ensure the safety of the product to the human body. The product is rich in salidroside, arbutin, etc., which can inhibit tyrosinase activity and melanin synthesis, so it has a strong whitening function on the skin, and has a synergistic effect with the components in the fermentation filtrate.

Description

technical field [0001] The invention belongs to the field of cosmetics, and relates to a Rhodiola rosea fermented puree cosmetic and a preparation method thereof. Background technique [0002] Rhodiola rosea is a rare medicinal plant that grows in the alpine and pollution-free areas of the northern hemisphere. It has beauty effects such as anti-aging, anti-oxidation, and whitening. At present, the cosmetics containing Rhodiola rosea ingredients in the market all add a certain proportion of Rhodiola rosea extract to the basic formula of the cosmetics. Give full play to the beauty effect of rhodiola rosea. Contents of the invention [0003] The object of the present invention is to provide a Rhodiola rosea fermented puree cosmetic and a preparation method thereof. [0004] The Rhodiola rosea fermented puree cosmetics provided by the present invention, its active ingredient is the supernatant obtained by the fermentation of the initial system fermented by mixing the root p...
