Mangiferin, a naturally occurring xanthone glucoside with potent antioxidant and antiinflammatory properties, is particularly abundant in the bark of Mangifera indica L. (mango tree) and can also be found in other parts of this plant. In this study, we looked at its abundance in the mango leaves. An ethanolic extract of leaves was prepared. The extract was then subjected to sequential extractions with hexane, ethyl acetate, n-butanol and water. Various fractions were investigated for antioxidant capacity and total phenolic content. Antioxidant capacities and phenolic content were detected in all fractions tested with the highest in the ethyl acetate fraction, 2.82 g trolox/g extract and 0.44 mg gallic acid/g extract, respectively. Mangiferin was found in both the butanol and water fractions. Mangiferin was isolated from the butanol fraction as a major component. The identity of mangiferin was confirmed by NMR spectroscopy.
