HPLC Characteristic Fingerprint of Jiuwei Qianghuo Granules / 中国药师

ABSTRACT

Objective:To provide scientific basis for the quality control of Jiuwei Qianghuo granules by establishing an HPLC char-acteristic fingerprint. Methods:The HPLC analysis was performed on a Sunfire C18 chromatographic column (250 mm × 4. 6 mm, 5μm) , and the mobile phase was acetonitrile-0. 1% phosphoric acid with gradient elution at the flow rate of 1. 0 ml·min-1 . The de-tection wavelength was 270 nm and the temperature of column was 30℃. Results:The common pattern of HPLC characteristic chroma-tographic profile was established. There were 15 common peaks,and four of which were identified in the pattern. The similarities of 12 batches of Jiuwei Qianghuo granules was evaluated,and all of them were greater than 0. 90. Conclusion:The analysis method of HPLC characteristic chromatographic fingerprint is simple and reproducible, which can provide scientific basis for the identification and quali-ty evaluation of Jiuwei Qianghuo granules.
