摘 要：
以市售5个样本苕子蜜为研究对象,在测定其总酚酸及总黄酮含量的基础上,研究苕子蜜对DPPH自由基的清除作用,并测定苕子蜜的还原力。结果表明:5个样本苕子蜜总酚酸含量在9.323～21.982mg/100g之间,总黄酮含量在0.842～2.295mg/100g之间。各样本苕子蜜均有一定的抗氧化活性,呈现量效关系。总酚酸含量、还原能力与抗氧化能力三者成正相关,表明蜂蜜的抗氧化活性可能与其所含的总酚酸有关。总黄酮和总酚酸含量与还原能力、抗氧化能力之间无明显相关性。

摘 要：
Five commercially available Vicia villosa Roth honeys were evaluated for contents of total phenolic acid and total flavonoids,reducing power and DPPH radical scavenging activity.Results indicated that the content of total phenolic acid in the samples theoretically equivalent to that of catechin varied from 9.323 to 21.982 mg/100 g honey,and the content of total flavonoids theoretically equivalent to that of rutin from 0.842 to 2.295 mg/100 g honey.All the honey samples exhibited some antioxidant activity in a dose-dependent manner.A positive correlation was observed between total phenolic acid content and DPPH radical scavenging activity or reducing power.This demonstrated that the antioxidant activity of these honeys may be linked to the total phenolic acid content.In addition,total flavonoids content had no obvious correlation with total phenolic acid content,reducing power or DPPH radical scavenging activity.
