[Studies on chemical components of Lobelia chinensis].Zhongguo Zhong Yao Za Zhi 2009; 34(3):294-7ZZ
To study on the chemical constituents of Lobelia chinensis.
The coloumn chromatographic techniques were applied to isolate constituents, and their structures were elucidated by means of spectral data analysis.
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).
All of these compouds were obtained from L. chinensis for the first time.
