Abstract:

A qualitative and quantitative test method of fingerprint of Wuji gastric floating sustained-release tablets was established. High performance liquid chromatography (HPLC) was adopted, using Agilent ZORBAX SB-C18 column (250 mm×4.6 mm, 5 μm) as the chromatographic column, and acetonitrile0.05 mol/L potassium dihydrogen phosphate solution as the mobile phase in a gradient elution with the flow rate of 1.0 mL/min. Sample solution (10 μL) was injected and was tested at the wavelength of 225 nm for 75 min at the column temperature of 30 ºC. Fingerprint similarity software (2004A version) was used to conduct data analysis. A total of 11 batches of Wuji gastric floating sustained-release tablets were tested and analyzed with HPLC fingerprint. Seventeen common peaks were found and the similarity of the 11 batches of agents was greater than 0.9, indicating that the production process of the agent is stable and feasible. The method is operable and could effectively control the quality of Wuji gastric floating sustained-release tablets.
