摘要: AIM: To develope a novel, simple and accurate fingerprint method for the quality control of Clerodendranthus Spicatus from different regions by high-performance liquid chromatography, which is widely used for urolithiasis. METHODS: Chromatographic separation was performed on Agilent SB-C18 (250 mm×4.6 mm, 5 μm) by the gradient elution of 0.1% H3PO4 in water and acetonitrile at 0.8 mL·min-1 at 210 nm by DAD detector. The column temperature was set at 30 °C. RESULTS: The method has good stability and reproducibility with RSD less than 2%. 10 peaks were selected as the common peaks. Rosmarinic acid was taken as a reference. The similarity of 10 batches was above 0.90. CONCLUSION: This method is simple and specific, which provided an effective way to assess the quality of Clerodendranthus Spicatus.
