Abstract: Objective To establish a method for the determination of schisandrin and catalpol in Jinji Zhongfeng No. 1 Granules. Methods Catalpol and schisandrin were determined by HPLC method, respectively. Catalpol was determined with acetonitrile- 0.1% phosphoric acid(1∶99) as the mobile phase, the flow rate was 1.0 mL/min, and the detection wavelength was 210 nm. Schisandrin was determined by methanol – water(75∶25) as the mobile phase, the flow rate was 0.8 mL/min, and the detection wavelength was 250 nm. Results The liner ranges of catalpol and schisandrin were 4.25 — 68.00 μg/mL(r=0.999 9), 4.00 — 32.00 μg/mL(r=0.999 9). The average recoveries were 100.22%,and 100.49%, with RSD values of 1.05%,and 1.25%(n=9), respectively. Conclusion The method is specific, accurate and reproducible, and can be used for the quality control of catalpol and schisandrin for Jinji Zhongfeng No. 1 Granules.
