Abstract:
OBJECTIVETo investigate the chemical constituents from the root and rhizome of Rheum rhizastachyum.
METHODThe compounds were isolated by column chromatography on silica gel, Sephadex LH-20, MCI-gel CHP-20P separately and their structures were elucidated by chemical and spectral technology.
RESULTSix compounds were isolated and identified as chrysophanol, emodin, gallic acid, sucrose, 1-O-beta-D-glucopyranosyl-chrysophanols, 1-O-beta-D-glucopyranosyl-emodin.
CONCLUSIONAll the compounds were obtained from this plant for the first time.
