摘要: 研究中草药中具有SOD样活性的有效成分, 可以为进一步开发利用中草药提供科学依据。从我国药材大黄中分离出四类化合物, 作者分别测定其中十五种化合物的SOD样活性。用其对超氧负离子自由基的清除率表示。实验结果表明, 四类化合物的SOD样活性不同: 大黄鞣质的儿茶精类化合物的SOD样活性较强, 其中以(-)-表儿茶精的活性最强; 芪甙类化合物的活性相对较弱; 而大黄酚-8-葡萄糖甙和去氧土大黄甙不但无SOD样活性, 还有促进超氧负离子自由基生成的作用。

关键词: 大黄, 超氧负离子自由基, SOD样活性

Abstract: It is important to search for the ingredients with SOD-like activity present in Chinese traditional drugs. Four classes of constituents including fifteen compounds isolated from Chinese rhubarb were studied for their SOD-like activity by determining the percentage of scavenging effect of the superoxide radical anion (O2-·), (S%), The results showed that the SOD-like activities of four tanninoid compounds were stronger among which (-)-epi- catechin has the strongest SOD-like activity at lower concentrations: the activity of five stilbene compounds is weaker:while chrysophanol-8-glucoside and desoxyrhaponticin have no SOD-like activity and, on the contrary.may promote the production of O2-·.

Key words: Rhubarb, Superoxide radical anion, SOD-like activity
