新疆红景天对油脂的抗氧化作用

THE STUDY OF ANTIOXIDANT EFFECTS ON GREASE ABOUT RHODIOLA ROSEA (GOLDEN ROOT, AICTIC ROOT) P.E

本试验采用Na2S2O3-I2测定POV值的方法,用新疆红景天乙醇提取物分别对五种油脂的抗氧化性进行研究,结果发现提取液对五种油脂有一定的抗氧化作用,对其作用机理作了初步的研究。

POV was determined by using Na2S2O3-I2 at different time, and the antioxidant effects on five kinds of greases were studied by using ethanol extraction of Rhodiola Rosea （Golden Root, Merle Root） P.E. The results were the antioxidant effects with anhydrous alcohol extraction solvent weren＇t obvious, and the antioxidant effects with CH3CH2OH extraction solvent were obvious. On this basis, preliminary analysis is made about antioxidant mechanism of it.
