摘要
A method was developed to quickly determine genistin, genistein, kaempferol and rutin in Fructus sophorae by β -CDmodified capillary zone electrophoresis. Based on the investigation of the effects of buffer pH and concentration, β -CD concentration,SDS concentration, capillary temperature, the analytical conditions were optimized. Under the optimized conditions, the three analytes were well separated in less than 6 min. A good linear relationship between the peak area and concentration was found in the 2 ~ 400g/mL,2 ~ 300g/mL 2 ~ 200g/mL and 5 ~ 500g/mL concentration range for genistin, genistein, kaempferol and rutin, respectively. The detection limits were 0.8g/mL, 0.6g/mL, 0.6g/mL and 1.4g/mL for genistin, genistein, kaempferol and rutin, respectively.
