| Abstract: | In order to optimize the extraction techniques of total flavonoids in Flemingia strobilifera,effects of concentration of solvent,the radio liquid to material,time length of extraction,and frequency of extraction on F.strobilifera total flavonoids yield were studied by single factor experiments and orthogonal experiments.The results showed that the optimum extraction techniques were extracting in 80% methanol with the ratio of liquid to material at 10∶1 for 4 times,with 2 hours for each time.The content of total flavonoids was 1.30% in extract.The optimized techniques are simple and feasible,which is an effective way to extract total flavonoids from F.strobilifera. |
