摘　　要：以新鲜益母草、茶花、油菜、荷花、玫瑰、籽瓜、菊花、荞麦8种常见的蜂花粉油脂为材料,测定其中的类胡萝卜素含量,同时评价不同蜂花粉油脂的抗氧化活性。结果表明:8种蜂花粉油脂对DPPH自由基均具有一定的清除作用,不同蜂花粉油脂清除能力存在显著差异(P<0.05),IC50值在0.212～7.110mg/mL之间。蜂花粉油脂中含有较高含量的类胡萝卜素类物质,其含量与油脂抗氧化活性呈正相关(R2=0.8645),表明类胡萝卜素可能是蜂花粉油脂抗氧化的主要活性成分之一。The contents of carotenoids and antioxidant activity of the oils extracted from eight kinds of common bee pollen were determined to analyze the correlation between the two parameters.Results indicated that all the eight bee pollen oils had scavenging effect on DPPH free radicals,but displayed a significant difference（P〈0.05） and their IC50 values for scavenging DPPH free radicals ranged from 0.212 to 7.110 mg/mL.Carotenoids was abundantly contained in bee pollen oil and the content of carotenoids was linearly correlated（R^2 = 0.8645） with antioxidant activity.These results indicate that carotenoids might be one kind of the predominant antioxidants in bee pollen oil.
