不同产地蜂胶的抗氧化活性评价

Antioxidant Activity of Propolis from Different Regions of China

目的测定中国不同地区蜂胶的总多酚含量和抗氧化化活性。方法通过测定DPPH、ABTS、OH-三种自由基体系9个产地蜂胶乙醇提取物的自由基清除能力,评价蜂胶的抗氧化活性。结果不同产地的蜂胶均有较强的自由基清除活性,但是总多酚含量和自由基清除能力存在差异,山东泰安蜂胶对三种自由基的清除能力都最强,其总多酚也最高。结论蜂胶具有较强的抗氧化活性,是一种天然有效的自由基清除剂。不同产地的蜂胶总多酚含量和抗氧化活性差异较大,抗氧化活性高的蜂胶总多酚含量也较高。

Objective To evaluate the antioxidant activity of propolis from different regions of China. Methods The free radical scavenging activity of propolis （ethanol extracts） was determined by three kinds of free radical scavenging systems （DPPH, ABTS, OH）. Results Propolis from different regions have strong free radical scavenging activities. However, the total polyphenols content and free radical scavenging activities varied greatly with the different origins. The free radical scavenging activities of Tai＇an propolis from Shandong province, accompanied with the highest total polyphenols content, was highest, Conclusion Propotis occupying strong antioxidant activityis a natural and effective free radical scavenger. The contents of total polyphenols and antioxidant activity of propolis from different regions were different, propolis has higher antioxidant activity with higher total polyphenol content.
