RP-HPLC fingerprint of Shentong granules / 中成药

AIM: To establish a RP-HPLC method to determine the fingerprint of Shentong granules. METHODS: Chromatographic conditions consisted of Alltech ODS column and the mobile phase composed of a mixture of acetonitrile-water(gradient elution),detection wavelength at 270 nm.The flow rate was 1.0 mL/min. RESULTS: A HPLC fingerprint determination with a good reproducibility was established,which could separate main principles of Shentong granules. CONCLUSION: The method can provide more information for the quality control of Shentong granules.
