摘要
分别采用Fenton反应和硫代巴比妥酸法(TBA)测定林檎叶提取物对·OH的清除作用及对动物肝脏匀浆脂质过氧化的抑制作用.结果表明,林檎叶经乙醇提取再经氢氧化钠溶解和乙酸乙酯溶解组分对·OH自由基有较好的清除作用,其清除率达70%以上.两组分同样有较好的脂质过氧化抑制作用.
Fenton and TBA methods were used to study the clearance effect of ·OH free radical and inhibition of malus doumeri leaf extracts on animal liver lipid peroxidation.The results showed that Malus doumeri leaf was extracted by ethanol,and then dissolved in NaOH solvent and ethyl acetate respectively which could effectively clean up the·OH free radical.The average scavenging rate was more than 70%.These two separating groups could inhabit effectively lipid peroxidation.
