摘要
以索氏提取法用60%乙醇提取芹菜叶中的黄酮类物质,分别采用生化试剂盒法测定其总抗氧化能力及对羟自由基(·OH)、超氧阴离子自由基(O2·)的清除能力,另对不同油脂的抗氧化性能进行检测,评价芹菜叶提取物的体外抗氧化作用。结果表明:芹菜叶乙醇提取物具有较强的抗氧化作用和清除·OH、O2·的能力,并且随提取物质量浓度增大,其总抗氧化能力及清除自由基能力增强,表现出明显的量效关系;芹菜叶乙醇提取物有显著的防止油脂氧化的作用,其效果优于VC。
Soxhlet extraction was used to extract flavonoids from celery.The antioxidant effect of celery extract was also investigated.The total antioxidant capacity and scavenging capability to free radicals were determined.Results showed that celery extract had strong anti-oxidation effect and scavenging capability to· OH and O2·.The increasing concentration of celery extract resulted in an enhanced anti-oxidation effect and scavenging capability to free radicals.Ethanol extract from celery also exhibited an obvious effect on the prevention of oil oxidation,which was stronger than that of vitamin C.
