benzofurans and medioresinol

To investigate the chemical constituents of Selaginella sinensis (Desv.) Spring.. Chromatographic separations on Diaion HP-20, silica gel, and Sephadex LH-20 were used. The structures of the isolates were elucidated on the basis of spectroscopic analysis, as well as chemical methods.. Eight compounds were obtained and their structures were identified as sinensioside A (1), syringaresinol-4- O-β-D-glucopyranoside (2), (+)-medioresinol-4-O-β-D-glucopyranoside (3), pinoresinol-4, 4'-di-O-β-D-glucopyranoside (4), quercetin (5), eucomic acid (6), shikimic acid (7), and 2, 3-dihydroamentoflavone (8).. Compound 1 is a new dihydrobenzofuran sesquilignan glycoside from Selaginella sinensis.
