摘要

A new chalcone glycoside, 2',4,4',6'-tetrahydroxydihydrochalcone 2'-O-alpha-L-rhamnopyranosyl-(1 -> 6)-beta-Dglucopyranoside (1), was isolated from Combretum griffithii Huerck et M.-A. along with the known compounds (-)-epigallocatechin (2), 3'-O-methyl-(-)-epicatechin (3), (-)-4'-O-methyl epigallocatechin (4), (-)-epicatechin (5), (+)-catechin (6), betulin (7), maslinic acid (8), oleanolic acid (9), arjunolic acid (10), sitoindoside I (11), glycerol 1-(9Z,12Z-octadecadienoate) (12), beta-sitosterol (13), and daucosterol (14). Their structures were elucidated by spectroscopic means and comparison with published data. All the compounds were isolated from Combretum griffithii for the first time.
