Author: NURFITRIANI.A, META MAHENDRADATTA, AMRAN LAGA, ZAINAL
Abstract: Purple Uwi (Dioscorea alata L.) is a type of tuber which is a prospective local food plant and can be used as a source of functional food. The purpose of this study was to analysis the phenol and flavanoid content of uwi sap (Dioscorea alata.L) extract. This research was carried out by extracting the sap of Uwi and then screening thin layer chromatography (TLC) phytochemicals. The results of this study showed that the uwi sap ethanol extract and the total rendamen of uwi sap ethanol extract at a concentration of 96% gave the rendamen amount of 39%. The ethanol extract of uwi sap based on phytochemical screening thin layer chromatography produced flavonoids. By ethanol extract, uwi sap can be used as a candidate for antioxidants and antibacterial properties.
