Objective:To develop an HPLC method for determination of 5 alkaloids of Radix Sophorae Flavescentis in Kuqi dropping pills.Methods:Inertsil NH2(150 mm×4.6 mm,5 μm) was adopted;The mobile phase was acetonitrile(A)-absolute alcohol(B)-3% phosphonic acid water solution(C) with gradient elution at a flow rate of 1.0 mL·min-1,and the detection wavelength was 210 nm.Results:The content of 5 alkaloids of Radix Sophorae Flavescentis was stable.The method has a good linearity in the ranges of 0.14-0.49 μg(r=0.9998) for sophocarpine,038-1.30 μg (r=0.9997) for matrine,0.06-0.20 μg(r=0.9991) for oxysophocarpine,0.05-0.18 μg(r=0.9991) for sophoridine,and 0.13-0.44 μg(r=0.9991) for oxymatrine;The average recoveris were 98.2%,98.3%,97.7%,98.3% and 98.9%,respectively.Conclusion:This method is dependable,simple and practica1,and may be used to control quality of Kuqi dropping pills.
