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 reaction and thiobarbituric acid method (TBA) were used to determine the scavenging effect of extracts of Rhododendron chinensis leaves on OH and lipid peroxidation of liver homogenate. The results showed that the leaves of Rhus lancifolium were extracted by ethanol and then The sodium hydroxide dissolved and ethyl acetate dissolved components had better scavenging effect on OH radicals, and the clearance rate was more than 70%. The two components also had good inhibition of lipid peroxidation.
