Phenolic glycosides from berries of Pimenta dioica

Four new phenolic glycosides, (2-hydroxy-3-methoxy-5-allyl)phenyl β-D-(6-O-E-sinapoyl)glucopyranoside (1), (1′ R,5′R)-5-(5- carboxymefhyl-2-oxocyclopentyl)-3Z-pentenyl β-D-(6-O-galloyl) glucopyranoside (2), (5)-α-terpinyl [α-L-(2-O-galloyl) arabinofuranosyl]-(l→6)-β-D-glucopyranoside (3), and (R)-a-terpinyl [α-L-(2-O-galloyl)arabinofuranosyl]-(l→6)-β-D-glucopyranoside (4), were isolated from the berries of Pimenta dioica together with eight known flavonoids. The structures of 1-4 were elucidated on the basis of MS and NMR data and enzymatic hydrolysis. All four glycosides showed radical-scavenging activity against 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radicals.
