Abstract:
OBJECTIVETo investigate the chemical constituents of Ligularia xanthotricha.
METHODSilica gel column chromatography and preparative TLC were employed for the isolation and purification. The structures were identified on the basis of spectral data (IR, EI-MS, 1H-NMR, 13C-NMR, DEPT) and chemical evidence.
RESULTSeven compounds were isolated and identified as follows: lupeol (1), lupeol palmitate (2), 3, 28-dihydroxyl-lupeol (3), betulinic acid (4), taraxasterol (5), taraxasteryl palmitat (6) and taraxasteryl acetate(7).
CONCLUSIONAll the compounds were isolated from this plant for the first time.
