| 摘 要： | 目的:研究一点红提取物体外抗氧化活性。方法:通过水提醇沉、有机溶剂萃取、大孔树脂吸附纯化,得到六种不同部位的样品。以抗坏血酸和2,6-二叔丁基-4-甲基苯酚为对照,测定样品对羟基自由基和二苯基苦基苯肼自由基的清除能力,对Fe3+的还原能力,抑制油脂的氧化能力。结论:上述样品均具有一定的抗氧化活性,其中大孔树脂纯化的50%乙醇洗脱部位活性最好,但总体上弱于抗坏血酸和2,6-二叔丁基-4-甲基苯酚。

| Abstract: | Objective:To study the antioxidant effects of extracts of Emilia sonchifolia(Linn.) DC.Methods:Get six different parts of the samples by water extraction and alcohol precipitation,organic solvent extraction,macroporous resin purification.Compared with the ascorbic acid and 2,6-di-t-butyl-4-methylphenol,these samples were tested for scavenging effects on the hydroxyl radical and the DPPH free radical,reducing ability and inhibiting capacity of oil oxidation.Conclusion:The results showed that the samples had antioxidant activities,the part of 50% ethanol elution showed the better activity than other samples,but weaker than the ascorbic acid and 2,6-di-t-butyl-4-methylphenol. |
