β-amyrin-3-(3{\textquoteright}-dimethyl) butyrate, a new natural compound was isolated from the fruits of\ Manilkara zapota\ (L.) Van Royen, in addition to lupeol-3-acetate and 4-caffeoylquinic acid (cryptochlorogenic acid). The structures of these compounds were identified using different spectral methods (IR, MS, UV,\ 1\ H-NMR,\ 13\ C-NMR and 2D-NMR). The alcoholic and aqueous extracts of the unripe fruits, in addition to their aqueous homogenate exhibited antioxidant, antihyperglycemic and hypocholesterolemic activities.
