Hydrolyzable tannins from Balanophora polyandra

open access: yesActa Pharmaceutica Sinica B, 2013
AbstractThis study reports an investigation of the chemical constituents of Balanophora polyandra Griff. Fifteen compounds were isolated by column chromatography on silica gel, Toyo-pearl HW-40C, Sephadex LH-20 and by HPLC. Their structures were elucidated as 1,4-di-O-galloyl-2-O-[(E)-p-coumaroyl]-β-D-glucopyranose (1), 1-O-galloyl-β-D-pyranglucose (2),
