Abstract:

目的：研究白毛乌蔹莓(Cayratia albifolia C. L. Li)乙醇提取物不同萃取部位抗氧化活性。方法：以VC为阳性对照，选取清除1,1-diphenyl-2-picrylhydrazyl (DPPH)自由基清除能力为抗氧化指标，探究白毛乌蔹莓乙醇提取物不同萃取部位抗氧化活性。结果：正丁醇层、乙酸乙酯层、二氯甲烷层、石油醚层DPPH清除能力分别为2.76、0.48、16.99、3.03 (mg/g) VC当量。结论：白毛乌蔹莓乙醇提取物二氯甲烷层的抗氧化能力最强，其次是石油醚层，正丁醇层，乙酸乙酯层活性最弱。
Objects: To study the antioxidant activity of different solvent extract of ethanol extract of Cayratia albifolia C. L. Li. Methods: VC was used as positive control; 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging ability was used as an antioxidant index; the antioxidant activity of different solvent extract of ethanol extract of Cayratia albifolia C. L. Li was studied. Results: The DPPH scavenging abilities of n-butanol layer, ethyl acetate layer, dichloromethane layer and petroleum ether layer were 2.76, 0.48, 16.99, 3.03 (mg/g) VC equivalent. Conclusion: The antioxidant activity of dichloromethane layer was the strongest, followed by petroleum ether layer, n-butanol layer and ethyl acetate layer.
