| 摘 要： | 以水为溶剂对春砂仁根、叶进行超声波浸提。通过测定还原能力及O2-.自由基清除率、.OH自由基清除率、DPPH.自由基清除率,比较春砂仁根、叶提取物与茶多酚的抗氧化活性。结果表明,春砂仁根、叶提取物都有一定的抗氧化性质;根、叶水提取物的还原能力最强;对O2-.自由基清除率大小顺序为:春砂仁叶提取物>茶多酚>春砂仁根提取物;对.OH自由基清除率大小顺序为:春砂仁根提取物>春砂仁叶提取物>茶多酚。

| Abstract: | The roots and leaves of Amomum villosum was extracted by water with the assistance of ultrasonic to get water extract.The antioxidant activities of the extracts and tea polyphenols were compared by various antioxidant assays,including total reducing ability,superoxide free radical(O2-·),hydroxyl free radical(·OH) and 2,2-Diphenyl-1-picrylhydrazyl free radical(DPPH·) scavenging rates.The results showed that both extracts from the roots and leaves had antioxidant activities in the four assays.The total reducing ability of water extract was the strongest during the six extracts.The order of superoxide free radical(O2-·) scavenging rate was: leave extract >tea polyphenols > root extract.The order of hydroxyl free radical(·OH) scavenging rate was: root extract > leave extract > tea polyphenols. |
