红花红色素的抗氧化活性

Studies on the Antioxidant Activity of Carthamin from Safflower (Carthamus tinctorius L.)

从红花中提取了红花红色素,研究了该色素对超氧自由基、DPPH自由基的清除作用,以及对β 胡萝卜素 亚油酸氧化体系的抑制作用,以此来评价红花红色素的抗氧化能力.结果表明,红花红色素对超氧自由基和β 胡萝卜素 亚油酸氧化体系均有较明显的抑制作用.

The antioxidant activity of carthamin extracted and purified from safflower was evaluated by determining the heatinduced oxidation in a linileic acid system with βcarotene, the decoloration of the 1,1diphenyl2picrylhydrazyl and the superoxide genernated from autoxidation of pyrogallol. The results indicated that carthamin could be used as a natural antioxidant in food, cosmetics and medicine industries.
