Simultaneous content determination of eleven ginsenosides in Fukang Tablets by UPLC-MS/MS
AIM To establish a UPLC-MS/MS method for the simultaneous content determination of pseudoginsenoside F11 and ginsenosides Rf,Rg1,Re,Rb1,Rb2,Rb3,Rg2,Rg3,Rc,Rd.METHODS The analysis was performed on a 40℃ thermostatic Phenomenex Kinetex F5 column(2.1 mm×100 mm,1.7 μm),with the mobile phase comprising of acetonitrile-2 mmol/L ammonium formate flowing at 0.3 mL/min in a gradient elution manner,and electron spray ionization source was adopted in negative ion scanning with multiple reaction monitoring mode.RESULTS Eleven ginsenosides showed good linear relationships within their own ranges(r>0.9900),whose average recoveries were 97.40%-103.74%with the RSDs of 1.76%-3.48%.CONCLUSION This sensitive,practical and reproducible method can be used for the quality control of Ginseng Radix et Rhizoma in Fukang Tablets.
