Abstract: Objective To develop a method for the determination of the dissolution of Zhibitai capsules. Methods The chromatographic analysis was carried out on a ZABAX-C18column(250 mm×4.6 mm,5 μm)with methanol-0.05% phosphate solution(60∶40) as mobile phase.The flow rate was 1.0 ml/min and the detection wavelength was 238 nm.According to the third dissolution method (small glass-method) described in the Pharmacopoeia of the People's Republic of China (2015Edition,Volume 4),the dissolution determination conditions were established using SOTAX AT7 intelligent drug dissolution instrument,and dissolution medium,rotational speed and sampling time were selected. Results The method showed perfect specificity under the established chromatographic conditions.The linear ranges of lovastatin was 1.63-122.2 μg/ml(r=1.000 0).The dissolution rates of the samples were consistent.The 1.0% sodium dodecyl sulfate in phosphate solution (pH 7.0) was selected as release media,rotational speed was 100 r/min,the sampling time point was 45 min.The dissolution limit was not less than 80% of the labeled amount. Conclusion The established method could be used for the dissolution determination and the quality control,and provide reference for the improvement of quality standards of Zhibitai capsules.
