Embodiment 1

[0013] The carambola extract is extracted by the following method: get 100 g of the dried and pulverized powder of carambola fruit, cold-soak in 1000 ml of 70% ethanol at room temperature, 500 W ultrasonic extraction for 2 times, each time for 30 min, combine 1800 ml of filtrates, and recover the solvent under reduced pressure To no alcohol smell, pass through AB-8 resin, elute with volume concentration 30% ethanol, collect 400ml of the eluted part, and evaporate to dryness to obtain the carambola extract.

[0014] Peanut shell extract is extracted according to the following method: Take 100 g of dried ground peanut shell powder, cold-soak in 1000 ml of 70% ethanol at room temperature, 500 W ultrasonic extraction twice, each time for 30 min, combine the filtrates with 1800 ml, and recover under reduced pressure Solvent until there is no alcohol smell, pass through AB-8 resin, elute with volume concentrations of 10% ethanol and 30% ethanol in turn, collect each fraction, 400ml e...

Abstract

The invention discloses a plant extract capable of inhibiting tyrosinase activity and application of the plant extract in cosmetics. The plant extract comprises a carambola extract and a peanut shellextract according to the mass ratio of 1:3. Compared with the prior art, the plant extract has the advantages that the plant extract compound has excellent performance in tyrosinase activity inhibition, half inhibition ratio (IC50) reaches 0.45mg / ml, and better technical effect is achieved; particularly, the plant extract compound is obtained by compounding the carambola extract and the peanut shell extract, which are extracted according to a special extraction method, according to the specific mass ratio, so that obvious synergistic interaction is achieved in terms of tyrosinase activity inhibition, and the plant extract can be applied to preparation of the cosmetics with whitening effect.

Description

technical field [0001] The invention relates to the field of daily cosmetics, in particular to a plant extract for inhibiting tyrosinase activity and its application in cosmetics. Background technique [0002] In recent years, people have become keen on plant cosmetics and beauty methods returning to nature. With the improvement of people's living standards and aesthetic standards, more and more people pursue and yearn for white and clean skin. Therefore, the research and development of whitening cosmetics and skin whitening preparations that can prevent spots and pigmentation caused by sunlight and other reasons are increasingly being paid attention to by cosmetics manufacturers and researchers in various countries. Whitening cosmetics have become a skin care product. One of the mainstream varieties of cosmetics. [0003] The role of whitening agents is to reduce the production of melanin by inhibiting the activity of tyrosinase or blocking the oxidation pathway of tyrosi...
