Chemical constituents isolated from extracts of Annona vepretorum Mart. (Annonaceae) leaves

Abstract

Annona vepretorum Mart. is a medicinal plant endemic to Brazil, popularly known as "araticum", “bruteira” and “pinha da Caatinga”. In this study, the chemical composition of different leaf extracts obtained from this species was evaluated. Chemical compounds were isolated by silica gel column chromatography, resulting in a mixture of steroids (β-sitosterol and stigmasterol) and a triterpene (lupeol acetate). Ethanol extract presented a precipitate insoluble in chloroform, which after washing was identified as the flavonoid rutin (quercetin-3-O-α-L-rhamnopyranosyl-(1'''→6'')-β-glucopyranoside). These compounds are being reported for the first time in A. vepretorum.
