Simultaneous content determination of twelve constituents in Tufuling Qiwei Powder by HPLC-MS/MS
AIM To establish an HPLC-MS/MS method for the simultaneous content determination of berberine,coptisine,gallic acid,corilagin,geniposide,toosendanin,rutinum,chlorogenic acid,luteolin,asiatica,emodin and astilbin in Tufuling Qiwei Powder.METHODS The analysis was performed on a 35℃ thermostatic Shim-pack GIST-HP C18 column (2.1 mm × 100 mm,3 μm),with the mobile phase comprising of methanol-water (containing 0.1% formic acid) flowing at 0.25 mL/min in a gradient elution manner,and electron spray ionization source was adopted in negative and positive ion detection with multiple reaction monitoring mode.RESULTS Twelve constituents showed good linear relationships within their own ranges (r≥0.9990),whose average recoveries were 94.83%-104.42% with the RSDs of 1.30%-4.88%.CONCLUSION This simple,rapid and accurate method can be used for the quality control of Tufuling Qiwei Powder.
