Objective To establish an HPLC method to simultaneously determine the contents of 3,6'-dimustard acyl sucrose, schisandrin A, and ginsenoside Rb1 in Yinao Capsules. Methods The separation was carried out on Agilent Eclipe Zorbax XDB C18 column (250 mm×4.6 mm, 5 μm). Detector was ued as DAD detector. The mobile phase was 0.1% phosphoric acid solution-acetonitrile with gradient elution. The detection wavelength was set at 321 nm (3,6'-dimustard acyl sucrose), 249 nm (schisandrin A), and 203 nm (ginsenoside Rb1). The volume flow was 1.0 mL/min, column temperature was room temperature, and injection volume was 10 μL. Results There had good linear relationships for 3,6'-dimustard acyl sucrose, schisandrin A, and ginsenoside Rb1 within the ranges of 0.193-19.300, 0.299-29.910, and 0.189-188.600 μg/mL, whose average recoveries were 99.5%, 99.7%, and 98.3% with RSD values of 1.2%, 1.1%, and 0.7%, respectively. Conclusion The method is simple, accurate, and rapid, which is suitable for the quality control for Yinao Capsules, and provides reference for improvement of quality control of the product.
