This 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 galloy-2-O-[(E)-p-coumaroyl]-β-D-glucopyranose(1),1-O-galloyl-β-D-pyranglucose(2),1-p-coumaryl-β-D-pyranglu-cose(3),1-O-(E)-caffeoyl-β-D-pyranglucose(4),1,3-di-O-galloyl-β-D-pyranglucose(5),1,6-di-O-galloyl-β-D-pyranglucose(6),1-O-(E)-caffeoyl-4-O-galloyl-β-D-pyranglucose(7),1-O-(E)-caffeoy1-6-O galloyl-β-D-pyranglucose(8),1-0-(E)-caffeoy1-4,6-di-O-galloyl-β-D-pyranglucose(9),1-O-(E)-caffeoyl-4,6-(S)-HHDP-B-D-pyranglucose(10),1,23,6-tetra-O-galloyl-β-D-pyranglucose(11),4,6-(S)-hexahydroxydi-phenoyl-(α/β)-D-glucose(12),1-O-(E)-caffeoyl-4,6-[1′,1″-3′,3″,4′,4″-tetrahydroxydibenzofurandicar-boxyl)]-β-D glucopyranose(13),flavogallonic acid(14),and phloretin-4′-O-β-D-glucoside(15)on the basis of spectral analysis.Compound 1 was a new hydrolyzable tannin,9 was obtained from this genus for the first time,and compounds 5,6 and 11-14 were isolated from this plant for the first time.
