摘要: 研究了茶皂素的纯化及纯化产物体外对马铃薯酪氨酸酶催化L-DOPA合成多巴醌的抑制作用及其机理。结果表明质量浓度为100 g/L时,市售茶皂素、经大孔树脂纯化的茶皂素TS及2种层析分离得到的茶皂素TS1和TS2对酪氨酸酶的抑制率分别为51.29%,90.06%,94.13%和82.47%;TS和TS1对酪氨酸酶IC50分别为48和40 g/L,抑制作用表现为可逆竞争性抑制,对酪氨酸酶的抑制常数分别为137和101 g/L。

Abstract: Purification of tea saponin as well as inhibitory effect and inhibiting mechanism for catalytic synthesis of DOPA quinone from L-DOPA by potato tyrosinase in vitro was examined.The tea saponin product that purchased from market,was treated with macroporous resin to get the preliminarily refined tea saponin product (TS).Then the TS were further purified by chromatographic method and two kinds of purified tea saponin product were produced as TS1 and TS2.Results show that at mass concentration of 100 g/L,the inhibition rate of the market product,the TS,TS1 and TS2 achieves 51.29%,90.06%,94.13% and 82.47% respectively.IC50 of TS and TS1 achieves 48 and 40 g/L respectively.The inhibition kinetics analyzed by Lineweaver-Burk plots show that the action of TS and TS1 express as reversible and competitive inhibition for conversion of L-DOPA.The inhibition constants for the TS and TS1 achieves 137 and 101 g/L respectively.

Key words: whitening cosmetic additive, tea saponin, tyrosinase, inhibition
