摘要
采用Fe2+诱导卵黄脂蛋白多不饱和脂肪酸发生脂质过氧化反应为模型,以硫代巴比妥酸反应物的光密度值为指标,观察了蜂胶对Fe2+诱导的脂质过氧化反应的抑制作用,结果表明,蜂胶可以抑制Fe2+诱导的脂质过氧化反应,呈现量效关系,同时对已受Fe2+诱导的脂质过氧化反应有一定的延缓和阻断作用,效果优于同浓度的芦丁和槲皮素。
Using the peroxidation of polyunsaturated fatty acid from yelk lipoprotein induced by Fe2+ as a model, the value of theabsorbtance of thiobaturic acid reactive substances (TBARS) at 532nm as an index, the inhlbitory effect of purified propolis on thepefoxidatlon of polyunsatljrated fatty acid from yelk lipoprotein induced by Fe2+ was studied. The results showed that the propolis couldinhibit the rate of the peroxidation of polyunsaturated fatty acid from yelk lipoprotein induced by Fe2+ with dose dependent effect.
