A feasible HPLC-DAD-ELSD method was developed to simultaneously determine 15 bioactive compounds （salidroside, specneuzhenide, magnoflorine, rosmarinic acid, salvianolic acid B, columbamine, jatrorrhizine, epiberberine, coptisine, palmatine, berberine, 5,7-dimethoxycoumarin, ginsenoside Rgl, ginsenoside Rbl and oleanic acid ） in FTZc for its quality control. The multiple wavelength detection mode of DAD was used. The chromatographic separation was performed on an Ultimate XB Cls column with gradient elution. The mobile phase A （acetonitrile） and B （0.25% glacial acetic acid and 0.13% triethylamine in water, v/v） were run at a flow rate of 0.8 mL/min. The developed method showed good precision and accuracy with overall intra- and inter-day variations of 0.7%-1.9% and 0.6%-3.0%, respectively. The recoveries measured at three concentration levels, varied from 95.5% to 103.8%. The validated method was successfully applied for the simultaneous determination of 15 bioactive compounds in three batches of FTZc. The results suggested that the developed method was convenient and reliable, particularly suitable for the routine quality control of FTZc.展开更多
