Abstract: Objective To study the chemical constituents of flavones in Lobelia chinensis Lour.Method The chemical constituents of flavones in Lobelia chinensis Lour were extracted with 70% ehtonal and isolated by various coloumn chromatography and recrystallization,and identified by various kinds of spectroscopic methods.Results 9 flavanoids were isolated and identified as apigenin(1),loteolin(2),Diosmetin(3),chrysoeriol(4),hesperidin(5),loteolin-7-O-β-D-glucoside(6),apigenin-7-O-β-D-glucoside(7),linarin(8)and diosmin(9).Conclusion All of these compouds were obtained from Lobelia chinensis Lour. for the first time.
