Abstract:
OBJECTIVETo study the chemical constituents of Elephantopus tomentosus.
METHODThe compounds were isolated by repeated HP20 macro porous adsorption resin column combined with Sephadex LH-20, ODS and silica gel chromatographies. The structures were identified on the basis of extensive spectroscopic data analysis and by comparison of their spectral data reported.
RESULTEighteen compounds were identified as 2-deethoxy-2beta-hydroxyphantomolin (1), 2beta-hydroxy-2-deethoxy-8-O-deacylphantomolin-8-O-tiglinate (2), 2beta-methoxy-2-deethoxyphantomolin (3), 2beta-methoxy-2-deethoxy-8-O-deacylphantomolin-8-O-tiglinate (4), molephantin (5), molephantinin (6), tricin (7), luteolin (8), quercetin (9), 3beta-friedelinol (10), 3beta-hydroxyolean-12-en-28-oic acid (11), 3, 5-di-O-caffeoyl quinic acid (12), 3,4-di-O-caffeoyl quinic acid (13), syringaresinol-4-beta-D-glucopyranoside (14), xylogranatinin (15), byzantionoside B (16), 2'-hydroxycinnamaldehyde (17), and caffeic acid ethyl ester (18).
CONCLUSIONCompounds 9, 11, 14-18 were separated from Elephantopus for the first time.
