Abstract


From the aerial parts of Glochidion eriocarpum, a new flavan glucoside, 5,7,3',4'-tetra-O-methyl-ent-epicatechin 3-O-b-D-glucopyranoside (1), a known flavan, 5,7,3,4-tetra-O-methylepicatechin (2), and three known triterpenes, lupeol (3), 3-epi-lupeol (4), and glochidonol (5), were isolated by using combined chromatographic separations. Their structures were elucidated on the basis of spectroscopic data.
