ABSTRACT
Objective:
To develop a RP-ion pair HPLC with wavelength switching for the simultaneous determination of 4 components (marine, oxymarine, salicylic acid, benzoic acid) in Fufang Kusheng Shuiyangsuan powder.Methods:
An Agilent ZORBAX SB-C18 column(150 mm× 4.6 mm, 5 μm) was used;the mobile phase was acetonitrile (A)-0.1% phosphoric acid solution (0.2 g sodium heptanesulfonate was added to 100 ml solution) at a flow rate of 1.0 ml·min-1;the detection wavelength was 220 nm in 0-12 min and 280 nm in 12-25 min;the column temperature was 30℃.Results:
The linear range of marine, oxymarine, salicylic acid and benzoic acid was 0.006 030-0.120 6 μg (r=0.999 4), 0.016 56-0.331 2 μg (r=0.999 9), 0.717 1-14.34 μg (r=0.999 9) and 0.512 0-10.24 μg (r=0.999 9), respectively;the average recovery was 98.14%, 97.20%, 97.05% and 98.39% with the RSDs of 1.38%, 0.32%, 0.81% and 1.26%(n=6) , respectively.Conclusion:
The method is simple and rapid, and can be applied in the simultaneous determination of 4 components in Fufang Kusheng Shuiyangsuan powder.
