ResumoTwo new chalcone glycosides 4'-O-(6″-O-galloyl-β-d-glucopyranosyl)-2',4-dihydroxychalcone (1) and 4'-O-(6″-O-galloyl-β-d-glucopyranosyl)-2'-hydroxy-4-methoxychalcone (2) together with one known chalcone glycoside 4'-O-β-d-glucopyranosyl-2'-hydroxy-4-methoxychalcone (3) were isolated from the stems of Entada phaseoloides. The structures of the new compounds were elucidated on the basis of extensive spectroscopic analysis, including HSQC, HMBC, (1)H-(1)H COSY, and chemical evidences. This is the first report of chalcone-type compounds isolated from the genus Entada.
