丹参提取物与几种抗氧化剂在浓缩EPA和DHA中的抗氧化作用比较

The Comparison of Antioxidant Effects among Tanshen and Several Other Antioxidants Used in Concentrated EPA and DHA

本文比较了丹参提取物（ＳＭＥＣ）、茶多酚、ＴＢＨＱ、ＢＨＴ等几种抗氧化剂在浓缩ＥＰＡ和ＤＨＡ中的抗氧化作用的强弱，表明，在相同浓度下，丹参提取物的抗氧化作用不如茶多酚、ＢＨＴ及ＴＢＨＱ，丹参提取物及茶多酚的抗氧化作用均随浓度的升高而加强，丹参提取物与ＢＨＴ或ＴＢＨＱ有阶同作用，共同使用可大大增强抗氧化作用。

In this paper we compared the antioxidant effects of the extract of tanshen(Salviamiltionhiza Bunge),extract of tea,TBHQ,BHT. It showS that the tanshen extract has obviousantioxidant effects,but lower than of extract of tea,TBHQ and BHT at the same concentration. Theantioxidant effects of the extracts of tanshen and tea increased as their concentration increased.Whenthe tanshen extract is used together with TBHQ and BHT,its,dntioxidant effects strengthen greatly, This demonstrates that tanshen extract has strang antioxidative synergetic effects.
