Lignan and neolignan glucosides, and tachioside 2'-O-4''-O-methylgallate from the leaves of Glochidion rubrum.
Thirteen compounds (1-13) were isolated from a MeOH extract of leaves of Glochidion rubrum. The structures of four new compounds were elucidated to be (-)-isolariciresinol 2a-O-beta-D-glucopyranoside (1), (7R,8S)- and (7R,8R)-4,7,9,9'-tetrahydroxy-3,3'-dimethoxy-8-O-4'-neolignan 7-O-beta-D-glucopyranosides (2 and 3, respectively), and tachioside 2'-O-4''-O-methylgallate (4) on detailed inspection of one- and two-dimensional NMR spectral data.
