A method with few markers to determine multicomponents was established and validated to evaluate the quality of Shenfu injection by ultraperformance liquid chromatography coupled with a photodiode array detector. The separations were performed on an ACQUITY UPLC BEH C18 (2.1 50 mm2, 1.7 mm) column. Methanol and 0.1% formic acid aqueous solution were used as the mobile phase. The flow rate was…
