Study on Antioxidant Components from Potato Leaves

Abstract

Abstract: The antioxidant components from sweet potato leaves were extracted with methanol,and then divided into a fewgroups with different organic solvents.The antioxdant activity of components from various extracts and partly purified ingredi-ents was investigated.It was found that the components from methylene chloride、ethanol、ethylacetate、acetone andpurified butanol components all possessed antioxidant activity.The antioxidant activities of components from methylenechloride、ethanol and purified butanol componts respectively were stronger than the antioxidant activity of 0.02%BHT.Thepurified butanol-component and thyl acetate-component B belonged flavonoid and polyphenol respectively.

Key words: sweet potato leaves, antioxidant, purification
