[Studies on chemical components of Lobelia chinensis].
OBJECTIVE
To study on the chemical constituents of Lobelia chinensis.


METHODS
The coloumn chromatographic techniques were applied to isolate constituents, and their structures were elucidated by means of spectral data analysis.


RESULTS
Sixteen compounds were isolated and identified as daucosterol (1), diosmetin (2), apigenin (3), chrysoeriol (4), loteolin (5), hesperidin (6), loteolin-7-O-beta-D-glucoside (7), apigenin-7-O-beta-D-glucoside (8), linarin (9), diosmin(10), 5,7-dimethoxy-8- hydroxycoumarin (11), palmitinic acid (12), lacceroic acid (13), stearic acid (14), beta-sitosterol (15), daucosterol (16).


CONCLUSIONS
All of these compouds were obtained from L. chinensis for the first time.
