| 摘 要： | 本文主要研究红薯茎叶提取物的抗氧化活性。选取二苯代苦味酰自由基（DPPH）体系、还原体系、Feton体系和亚油酸过氧化体系，对采用系统溶剂法获得的红薯茎叶提取物进行抗氧化活性实验。结果表明，红薯茎叶具有良好的清除自由基的能力，但抗脂质过氧化能力较弱，其还原能力与清除自由基的能力关系密切。 |
| 关 键 词： | 红薯茎叶 抗氧化 自由基 还原能力 |

| Abstract: | The paper studied the antioxidant activity of the extracts of sweet potato stem and leaf (SPSL) by using the assays of DPPH radical, reducing power, hydroxyl radical and lipid peroxidation of linoleic acid (LA) was studied in this paper. The results showed that the extracts of SPSL had strong effect of scavenging free radicals, but it was weaker on the inhibition of lipid peroxidation, and there was a close correlation between scavenging free radicals and inhibition of lipid peroxidation. |
| Keywords: | sweet potato stem and leaf antioxidant activity radical reducing power |
