Phenyl derivatives from the leaves of the vietnamese plant antidesma hainanensis

Abstract

Five phenyl derivatives 1-O-(2′,4′ -dihydroxy-6’-methoxyphenyl)-6-O-(4′′-hydroxy-3′′,5′′-dimethoxybenzoyl)-β-D-glucopyranoside (1), 4′-O-[6′′-O-(4′′′-hydroxy-3′′′,5′′′-imethoxybenzoyl) -β-D-glucopyranosyl]-3′-hydroxyphenethyl alcohol (2), 4-hydroxymethyl-2-methoxyphenyl-6′-O-syringoyl-β-D-glucopyranoside (3), phenethyl-6-O-α-L-arabinofuranosyl-β-D-glucopyranoside (4), and 1-O-syringoyl-β-D-glucopyranoside (5) were isolated from the methanol extract of the leaves of the Vietnamese plant Antidesma hainanensis. Their chemical structures were determined using 1D, 2D-NMR and ESI-MS analysis as well as by comparison with reported data. This is the first report of these compounds from A. hainanensis.
