摘要
采用不同提取方法提取山楂活性成分,分别用DPPH法、邻苯三酚自氧化法测定了不同提取物的抗氧化作用。结果表明,不同提取物均有抗氧化活性,提取物量与抗氧化活性呈正相关,不同提取物抗氧化活性强弱为:醇提物>超临界CO2提取物>水提物。山楂提取物中乙酸乙酯萃取部分抗氧化活性最强。
The anti-oxidative effect of hawthorn extracts origin from different process were study by using DPPH and pyrogallol autooxidation methods in this manuscript.The results showed that all of them had anti-oxidative activity,and exhibit a positive correlation with the concentration and the anti-oxidative activity of the extracts.Among of them,the order of anti-oxidative effect was listed as follows： obtained from ethanol bath〉SFE-CO2〉water.The ethyl acetate part of hawthorn extracts demonstrated the strongest anti-oxidative activity.
