Rhodiola sachalinensis A.Bor ,as a natural medical plant, play an important role in pharmacology. The extract of Rhodiola sachalinensis A.Bor contains many kinds of organic principles , such as matters of antioxygen and others which can inhabit the activation of tyrosinase.As we known, the produce of melanin is responsible for the process of skin blackening. Besides, tyrosinase is a key enzyme which can catalyze tyrosine to L-DOPA ,and catalyze L-DOPA to dioxyphenylalanine quinone.Free radicals ,a matter produced in vivo ,which is close connection with ageing, is instable but powerful in oxidation . If plenty of the free radicals produced without efficient cleaning, the organism will be ageing uninterrupt . This paper do some research on the effect of the extract of Rhodiola sachalinensis A.Bor on the antioxygen and cosmetology .From the research of the effect on the inhibition ratio of the tyrosinase and the cleaning of free rdicals,we get the following results : 1. We used two approachs to get the extract of the Rhodiola sachalinensisA.Bor .one is to extract in water, the other one is to extract in alcohol. Extractapproachs in alcohol is including: circumfluence extract and marinatingextract.
