Objective: To study on the chemical constituents of Lobelia chinensis.
Method: The coloumn chromatographic techniques were applied to isolate constituents, and their structures were elucidated by means of spectral data analysis.
Result: 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).
Conclusion: All of these compouds were obtained from L. chinensis for the first time.
