采用水杨酸法、二苯代苦味肼基自曲基(DPPH·)法和Fe~(3+)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,其抗氧化能力小同;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.
採用水楊痠法、二苯代苦味肼基自麯基(DPPH·)法和Fe~(3+)還原力測定實驗,對鹿蹄草醇提物的石油醚、氯倣、乙痠乙酯、正丁醇和水萃取物進行體外抗氧化活性評價,以VC作暘性對照.結果錶明,同一提取物在不同的評價方法中,其抗氧化能力小同;不同極性提取物在同一箇評價指標上抗氧化能力差彆較大.

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-pierylhydrazyl (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.
