摘　　要：本文以沙芥叶片为原料,提取沙芥叶片总黄酮。从沙芥叶总黄酮的粗提物与纯化物对羟自由基(?OH?)、超氧阴离子(O2-)和DPPH自由基的清除能力和对Fe3+的还原能力,比较系统的剖析了沙芥叶总黄酮的抗氧化能力。实验表明沙芥叶片总黄酮在化学本质上具有一定的抗氧化能力,整体抗氧化能力大小顺序为:纯化物>BHT >粗提物。We extracted the total flavonoids from leaf mustard leaf with mustard leaf as raw material. Com-pared the crude extract and the purified material of the total flavonoids from the leaves of Pugionium cornutum in the ability to eliminate hydroxyl free radical (?OH?), superoxide anion (O2-) and DPPH radical, and to restore Fe3+, its antioxidant capacity of total flavonoids was analyzed systemat-ically. It showed that the total flavonoids from the leaves of Pugionium cornutum have antioxidant capacity. The order of the overall antioxidant capacity is: purified material >BHT >crude extract.
