摘要:

采用水杨酸法、二苯代苦味肼基自由基(DPPH·)法和Fe3+ 还原力测定实验,对鹿蹄草醇提物的石油醚、氯仿、乙酸乙酯、正丁醇和水萃取物进行体外抗氧化活性评价,以VC 作阳性对照。结果表明,同一提取物在不同的评价方法中,其抗氧化能力不同;不同极性提取物在同一个评价指标上抗氧化能力差别较大。

关键词: 鹿蹄草, 抗氧化能力, 清除自由基, 还原力

Abstract:

Antioxidant activities in vitro of extracts from Pyrola corbieri using petroleum ether, chloroform, ethyl acetate, n-butanol or water were evaluated by salicylic acid, 2,2-diphenyl-1-picrylhydrazyl (DPPH·) and ferric reducing/antioxidant power (FRAP) assays under the reference of vitamin C. Results indicated that antioxidant activities of extracts exhibited an obvious difference due to different evaluation methods. Similarly, the antioxidant activities of extracts with different polarities measured by the identical assay method also exhibited a significant difference.

Key words: Pyrola corbieri, antioxidant activity, free radical scavenging activity, reducing power
