Extracts of wild grape (Ampelocissus martini Planch.) roots were fractionated by silica gel chromatography using different solvent systems and were then assayed for their phytochemical contents and antioxidant activity. High levels of total phenolic and flavonoid content were found in both crude extract and chromatographic fractions. The ethyl acetate: methanol (75:25 %v/v) fraction had the highest level of total phenolics and flavonoids as well as antioxidant activity assessed all methods, except ABTS assay. This indicated that eluting solvents directly affected phytochemical profile and activity. Moreover, the phenolic and flanonoid substances showed highly positive correlation coefficient (r) to antioxidant activity. This suggested that the wild grape root is a natural source containing high phytochemicals with antioxidant activity which might be used as active ingredients supporting good health.
