ABSTRACT
Objective:
To investigate the chemical constituents in flowers of Gentiana tibetica.Methods:
The chemical constituents were isolated from the 95% alcohol extract of G. tibetica flowers by silica column chromatography, Sephadex LH-20, C18 and RP-HPLC. Their chemical structures were elucidated on the basis of IR, ESI-MS, 1H-MNR, and 13C-MNR spectroscopic data.Results:
Twelve compounds, including chromene, flavones C-glycosides, secoiridoid glycosides, iridoid glycosides, aliphatic alcohol, and disaccharide, were obtained from the 95% alcohol extract of G. tibetica flowers, Their structures were identified as macrophylloside D (1), orientin 7-caffeate (2), 7-O-feruloylorientin (3), isovitexin (4), saponarin (5), isoorientin (6), 6'-O-β-D-glucopyranosyl gentiopicroside (7), sweroside (8), swertiamarine (9), loganic acid (10), 1-heneicosanol (11), and sucrose (12).Conclusion:
Compounds 1-12 are isolated from G. tibetica for the first time.
