OBJECTIVE
To study trace chemical constituents contained in traditional Chinese medicine Trachelospermum jasminoides.
METHODS
The chemical constituents were separated and purified by using such column chromatographic methods as ployamide, silica gel, Sephadex LH-20 and ODS, and their structures were identified on the basis of spectral data analysis.
RESULTS
Eleven compounds were separated from T. jasminoides and identified as bergenin (1), chrysoeriol-7-O-beta-D-glucoside (2), arctigenin-4'-O-beta-gentiobioside (3), matairesinol 4'-O-beta-gentiobioside (4), traxillagenin (5), traxillaside (6), 4-demethyltraxillagenin (7), luteolin-7-O-beta-gentiobioside (8), arctiin (9), trachelogenin-4'-O-beta-gentiobioside (10) and luteolin-7-O-beta-D-glucoside (11).
CONCLUSIONS
Compounds 1 and 2 were separated from Trachelospermum genus for the first time, while compounds 3-7 were separated from this plant for the first time.
