中文摘要：

目的：研究治疗冠心病中药复方缓释制剂的均衡释放度。方法：采用高效液相色谱法和气质联用法进行测定。结果：以丹酚酸B为指标的水溶性成分的溶出符合Higuchi方程，以丹参酮ⅡA为指标的脂溶性成分的溶出符合Higuchi方程，挥发性戍分冰片的溶出符合一级方程和Higuehi方程。结论：高效液相色谱法具有快速、简便稳定等特点，可用于评价中药复方缓释制剂体外释放度，气质联用法可用于评价冰片的释放度。

英文摘要：

Objective To study the balanced release of slow-release TCM compound preparations for the treatment of coronary heart disease. Method To conduct the test in the study by HPLC and combined GC-MS. Result The dissolving-out degree of water-soluble components of the said preparations with salvianolic acid B as index is up to Higuchi equation, that of liposoluble components of the preparations with Tanshimone Ⅱ A as index is in conformity to Higuchi equation and that of volatile components of bormeol accords with the first-order equation and Higuchi equation. Conclusion Owing to its characteristics of rapidity, convenience and stability HPLC can be used to assess the in vitro release degree of slow-release TCM compound preparations and the combined GC-MS be used to assess the release degree of bormeol.
