目的:考察不同粒径的莲子心微囊的体外释药特点。方法:总生物碱含量测定采用UV法,以莲子碱为对照品;体外溶出度测定采用桨法,操作按中国药典所载桨法进行溶出度测定。结果:莲子心微囊的体外释放符合H iguch i释药模式。结论:不同粒径的莲子心微囊的释放趋势基本一致。
Objective: To investigate the in vitro drug release characteristics of lotus seed microcapsules with different particle sizes. Methods: The total alkaloid content was determined by UV method and lotus seed was used as the reference substance. The in vitro dissolution was measured by paddle method. The dissolution was determined according to the paddle method in Chinese Pharmacopoeia. Results: The in vitro release of lotus core microcapsules conforms to the H iguch i release pattern. Conclusion: The release trends of lotus core microcapsules with different particle sizes are basically the same.
