Abstract:
OBJECTIVETo investigate the nonvolatile chemical constituents from the ethanol extract of the stems of Pogostemon cablin.
METHODThe constituents were isolated and purified by repeated column chromatography on silica gel and Sephadex LH-20. Their structures were identified by physicochemical properties and spectroscopic analysis.
RESULTTwelve compounds were isolated and identified as tilianin (1), diosmetin-7-O-beta-D-glucopyranoside (2), 3"-O-methylcrenatoside (3), uracil (4), soya-cerebroside I and II (5), agastachoside (6), apigenin-7-O-(3", 6"-di-(E) -p-coumaroyl) -beta-D-galactopyranoside (7), 5-hydroxy-3, 3', 4', 7- tetramethoxy flavone (8), 4', 5-dihydroxy-3, 3', 7-trimethoxyflavone (9), acacetin (10), crenatoside (11), isocrenatoside (12).
CONCLUSIONCompounds 1, 2, 4-7, 10 were isolated from the genus Pogostemon for the first time.
