New triterpenoid acyl derivatives and biological study of Manilkara zapota (L.) Van Royen fruits., m Fayek, Nesrin, Monem Azza Abdel R., Mossa Mohamed Y., and Meselhy Meselhy R. , Pharmacognosy research, 2013 Apr, Volume 5, Issue 2, p.55-9, (2013) Abstract

β-amyrin-3-(3'-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.
