Abstract

OBJECTIVE

To study the chemical constituents of Taraxacum mongolicum.

METHOD

Repeated column chromatography over silica gel, C-18 and Sephadex LH-20 were used to isolate chemical constitutes and their structures were elucidated by spectroscopic methods MS, 1H-NMR, 13C-NMR including 2D-NMR techniques and by direct comparing spectral data with those reported in literatures.

RESULT

Eight compounds were identified as artemetin (1), quercetin (2), luteolin (3), luteolin-7-O-beta-D-glucopyranoside (4), caffeic acid (5), esculetin (6), stigmasterol (7), taraxasteryl acetate (8), respectively.

CONCLUSION

Compound 1 was obtained from this genus and compound 6, 8 from this species for the first time. Furthermore, the 13 carbon data of compound 6 from the literature were corrected with 2D-NMR techniques in this paper.
