Abstract:
OBJECTIVETo study the chemical constituents of the essential substance from the Polygonum oriental.
METHODChromatographic techniques were employed for isolation and purification of the constituents and their structures were determined by spectral analysis and chemical evidence.
RESULTSeven compounds were obtained and identified as ombuine-3-O-beta-D-galactopyranoside (1), ombuine-3-O-rutinoside (2), tryptophan (3), quercetin-3-O-methyl ether (4), kaempferol-3-O-(2"-O-alpha-L-rhamnopyranosyl) -beta-D-glucuronopyranoside (5), quercetin-3-O-(2"-O-alpha-L-rhamnopyranosyl)-beta-D-glucuronopyranoside (6), quercetin-3-O-beta-D-glucuronide (7).
CONCLUSIONCompounds 4-7 were isolated from P. oriental for the first time and compounds 1-3 were firstly obtained from the genus Polygonum. The total 1H and 13C-NMR date of compound 1 were assigned for first time.
