摘　　要：本研究制备不同黄酮含量的聚乙烯膜,测定纯水提取物和60%乙醇水溶液中总还原能力、ABTS^(+)自由基清除率、羟基自由基清除率,研究不同黄酮含量、浸泡天数对抗氧化能力的影响。结果表明,在总还原力实验中,随着时间的延长,60%乙醇水浸泡液的吸光度高于纯水浸泡液;随着天数的增加,各溶液提取物中的羟基自由基清除率和ABTS^(+)自由基清除率基本呈增加的趋势,黄酮添加量对羟基自由基清除率没有明显影响,但随着天数的增加,掺入黄酮的比例越高,ABTS^(+)自由基清除作用越显著。In this study,polyethylene films with different flavonoids contents were prepared,and the total reducing capacity,ABTS^(+)free radical clearance and hydroxyl radical clearance in pure water extract and 60%ethanol aqueous solution were determined.The effects of different flavonoids contents and soaking days on the antioxidant capacity were studied.The results showed that in the total reducing power experiment,the absorbance of 60%ethanol aqueous solution was higher than that of pure aqueous solution with the extension of time.With the increase of the number of days,the hydroxyl free radical clearance rate and ABTS^(+)free radical clearance rate in the extracts of each solution basically showed an increasing trend,and the addition of flavonoids had no obvious effect on the hydroxyl free radical clearance rate.The higher the proportion of flavonoids added,the more significant the scavenging effect of ABTS^(+)free radicals was.
