Objective:
To study trace chemical constituents contained in traditional Chinese medicine Trachelospermum jasminoides.
Method:
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.
Result:
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).
Conclusion:
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.
