title: [Chemical constituents from Pachysandra terminalis].
abstract: To study chemical constituents from Pachysandra terminalis. By repeated column chromatography, including silica gel, Toyopearl HW-40, and preparative HPLC, four new (14) and one known (5) compounds were isolated and purified. On the basis of spectral data analysis, the structure of isolated compounds were elucidated as follow: 2-methyl-3-methylenepentane-1, 2, 5-triol (1), 4-methyl-3-methylenepentane-1, 2, 5-triol (2), 4-methyl-3-methylenepentane-1, 2, 5-triol-5-O-beta-D-glucopyranoside (3), 4-methyl-3-methylenep- entane-1, 2, 5-triol-1-O-beta-D-glucopyranoside (4), (7S, 8R, 8' R)-(+)-lariciresinol-9-O-beta-D-glucopyrano-side (5). Compound 5 was isolated from this genus for the first time.
