Antioxidant activity, phenolic and total flavonoids from sweet potato ethanol extract (Ipomea batatas L.) of different varieties (white, yellow, orange and purple) were studied. Sweet potatoes were collected from Research Centre for Chemistry. Sweet potato leaves have been used for numerous oxidative-associated diseases such as cancer, allergy, aging, HIV and cardiovascular. 1,1-diphenyl-2-picryl hydrazyl (DPPH) method was used to investigate antioxidant activity in leaves, in which the yellow and purple varieties showed the highest and the lowest scavenging activities of 47.65 μg/ ml (IC50) and 87.402 μg/ ml (IC50), respectively. In this study, the yellow leaves showed the highest concentrations of total phenolic and flavonoids contents at 11.293 μg/g and 44.963 μg/g, respectively. Therefore, sweet potato leaves can be used as a prospective natural antioxidant. [ABSTRACT FROM AUTHOR] |
