Objective To set up a method for determining Specnuezhenide in Shengxinfa Capsules. Methods With HPLC method, Agilent TC-C18 column (4.6 mm×250 mm, 5 μm) was used. Mobile phase was methanol-water (35∶65), the flow rate was 1.0 mL/min, and the detecting wavelength was at 224 nm. Results The linearity was in the range of 0.15-0.90 μg. The average recovery was 100.35%, and RSD was 1.43%. Conclusion The method is accurate, reliable, and can be used for the determination of Specnuezhenide in Shengxinfa Capsules for its quality control.
