摘要: 本实验分别对同一地点春季和秋季采集的角叉菜样品采用95%乙醇进行提取。采用化学方法产生超氧阴离子自由基、羟自由基和小鼠肝匀浆液脂质过氧化体系对提取物进行抗氧化活性检测,研究其清除自由基和抑制脂质过氧化能力的差异。结果表明:春秋季节角叉菜样品的乙醇提取物对超氧阴离子自由基、羟自由基具有较显著的清除作用,同时对小鼠肝匀浆液的脂质过氧化作用也有一定的抑制作用。

Abstract: Chondrus ocellatus collected in spring and autumn on the same seaside, respectively, was extracted by 95% ethanol. Antioxidant activities of extractions were determined by chemical methods to produce superoxide free radicals, hydroxide free radicals and lipid peroxide of rat liver microsome. The results indicated that Chondrus ocellatus collected in different seasons can all scavenge superoxide free radicals and hydroxide free radicals. At the same time, they all show activities to inhibit lipid peroxide of rat liver microsome to certain degree. In addition, they show significant difference between the two extractions from Chondrus ocellatus in different seasons.

Key words: spring, autumn, Chondrus ocellatus, extraction, antioxidant activities
