摘要
目的:研究复方丹参缓释片溶出度,探索中药复方缓释制剂的评价方法。方法:采用转篮法和高效液相色谱指纹图谱评价。结果:通过对6个时间点进行取样测定,丹参缓释片水溶性成分能够比较均衡的释放出来,具有一致的均衡释放行为,从丹酚酸B的释放行为来看较符合Higuchi方程释放,以人参皂苷Rg1的释放行为来看较符合零级释放。结论:丹参缓释片水溶性成分溶出度具有良好的缓释行为。方法快速、简便稳定,可用于评价复方丹参缓释片水溶性成分体外释放度。
Objective： To study on the release of compound Danshen sustalned-release tablet and the evaluate method of Chinese material medica compound sustained-release preparation. Method： Rotating basket method and HPLC were employed. Result： Through the determination of 6 time-point samples, the water-soluble compositions of compound Danshen sustained-release tablet had a Well-balanced release behavior with a zero-grade release model or Higuchi release model. Conclusion： Compound Danshen sustained-release tablet had a zero-grade release model. The method was rapid and stable and could be applied to evaluate the water-soluble composition release of compound Danshen sustained-release Tablet.
