Simultaneous determination of ten constituents in Jingfang Granules by HPLC-MS/MS / 中成药

ABSTRACT

AIM To establish an HPLC-MS/MS method for the simultaneous content determination of pulegone,prim-O-glucosylcimifugin,5-O-methylvisammioside,columbianadin,saikosaponin a,saikosaponin d,ferulic acid,naringin,liquiritin and glycyrrhizic acid in Jingfang Granules.METHODS The analysis of methanol extract of this drug was performed on a 30℃thermostatic ZORBAX Eclipse Plus C18 column(2.1 mm×150 mm,1.8 μm),with the mobile phase comprising of methanol-0.1%formic acid flowing at 0.3 mL/min in a gradient elution manner,and electron spray ionization source was adopted in positive and negative ion scanning with multiple reaction monitoring mode.RESULTS Ten constituents showed good linear relationships within their own ranges(r>0.996 5),whose average recoveries were 96.7%-98.8%with the RSDs of 0.9%-1.9%.CONCLUSION This rapid,simple,sensitive and specific method can be used for the quality control of Jingfang Granules.
