摘　　要：研究了三种豆科牧草刺叶锦鸡儿、白皮锦鸡儿和盐豆木地上部分乙醇提取物及其不同极性萃取部分的抗氧化活性。刺叶锦鸡儿和白皮锦鸡儿乙酸乙酯萃取部分较其它部分抗氧化活性强。盐豆木石油醚萃取部分和乙酸乙酯萃取部分具有较强的抗氧化活性。结果表明，刺叶锦鸡儿和白皮锦鸡儿中的抗氧化活性成分主要为极性中等的化合物，盐豆木中的抗氧化活性成分主要为极性较小和中等的化合物。Crude ethanol extracts and different polar fractions of three leguminous forages （ i. e. Caragana acanthophylla, C. leucophloeal and Halimodendron halodendron） in Xinjiang of China were studied for their antioxidant activity. The ethyl acetate fractions of C. acanthophylla and C. leucophloeal exhibited the strongest antioxidant activity in their extracts and fractions. Both petroleum ether fraction and ethyl acetate fraction of H. halodendron demonstrated strong antioxidant activity. It suggested that the antioxidant components with their moderate polarity mainly exist in the ethyl acetate fractions of three plant species.
