Abstract: The rancimat method was applied in our experiment to study the antioxidative activity of the extracts of ArtemisiaSelengensis Turcz(AST). It was found that the extracts had strong antioxidative activity and the activity was in directly proportionto the usage of extracts. Different antioxidative activities were showed in different oxidation feaction systems. That is theantioxidative effect in emulsification system was better than that in oil system. The antioxidative activity of extracts wascompared with that of PG and BHT, and when the additive quantity of the extracts reached 0.10%,its antioxidative activity wasstronger than that of 0.02% BHT, and weaker than that of 0.02% PG.The extracts, in the presence of citric, tartaric acid or VitaminC, exhibited remarkable synergistic effect on rice bran oil.
