中文摘要: 用高效液相色谱对蜂胶乙醇提取物(EEP)中的芦丁和槲皮素含量进行测定,并对不同处理方法得到的 EEP 进 行抗氧化性能研究。结果表明,芦丁和槲皮素在不同试验样品的含量分别为:粗蜂胶中的含量分别是 1.823 %和 6.03 %, 超声波辅助乙醇提取物中的含量分别为 3.134 %和 6.138 %,经大孔树脂纯化后其含量分别为 4.256 %和 13.483 %。通过 Schaal 烘箱法表明蜂胶中黄酮类化合物含量越高,抗氧化效果越好。
Abstract:The content of rutin and quercetin of ethanol extract of propolis was determined by HPLC,and the antioxidant activity of ethanol extract of EEP was also researched. Analysis showed: the content of rutin and quercetin was 1.823 % and 6.03 % respectively in crude propolis;3.134 % and 6.138 % respectively in ultrasonic assisted ethanol extract of propolis;4.256 % and 13.483 % respectively in purification by macroreticular resin.It showed that the more flavonoids contents of the propolis ,the better antioxidant activity by Schaal oven method.
