| 摘 要： | 采用甲醇、乙醇、乙醚、乙酸乙酯、石油醚、丙酮6种溶剂分别对角叉菜进行冷浸提取.对提取物进行超氧阴离子自由基(.O2-)、羟自由基(.OH-)、H2O2诱导的小鼠红细胞氧化溶血和小鼠肝匀浆脂质过氧化的清除作用实验.结果表明,角叉菜不同溶剂提取物对各种自由基均具有一定的清除作用,而且溶剂对提取物活性有一定的影响.在相同的浓度下,对自由基的清除作用最大的分别为乙醚、丙酮、乙醚和乙酸乙酯提取物.

| Abstract: | Chondrus ocellatus was extracted by methanol,ethanol,ethyl ether,ethyl acetate,petroleum ether and acetone,respectively.Antioxidant activities of these extracts were determined by scavenging effect on superoxide free radicals,hydroxide free radicals,H2O2 induced hemolysis of rat erythrocytes and lipid peroxide of rat liver microsome.The results indicate that different extracts of Chondrus ocellatus all show some antioxidant activities on different free radicals,and solvents have some effects of extracts on ... |
