| Abstract
| - Three new galloylglucosides, (4S)-α-terpineol 8-O-β-d-(6-O-galloyl)glucopyranoside (1); (4R)-α-terpineol8-O-β-d-(6-O-galloyl)glucopyranoside (2), and 3-(4-hydroxy-3-methoxyphenyl)propane-1,2-diol 2-O-β-d-(6-O-galloyl)glucopyranoside (3), were isolated from the berries of Pimenta dioica together with threeknown compounds, gallic acid (4), pimentol (5), and eugenol 4-O-β-d-(6-O-galloyl)glucopyranoside (6).The structures of 1−3 were elucidated on the basis of MS and NMR spectral data and enzymatic hydrolysis.These galloylglucosides (1−3, 5, and 6) showed radical-scavenging activity nearly equivalent to that ofgallic acid (4) against 1,1-diphenyl-2-picrylhydrazyl radical.
