| 摘 要： | 目的:研究并制定绿康银杏叶片的质量控制方法.方法:采用薄层色谱法对绿康银杏叶片中的有效成分银杏叶内酯进行定性鉴别,采用GC/MS法测定其中紫苏子脂肪油中的脂肪酸组成,并用高效液相色谱法测定银杏黄酮、银杏内酯的含量,对其中限量的银杏酸进行了测定.结果:精密度试验RSD为1.2%～2.5%(n=5),稳定性试验24 h内稳定不变,峰面积与其浓度线性关系良好(r值均为0.999以上),平均回收率均为95%以上.结论:本法结果准确,可作为该制剂的质量控制方法.

| Abstract: | OBJECTIVE: The quality control method of "Lü Kang Yin Xing Ye Pian" (LKYXYP) was studied and established. METHOD: The ginkgolides in LKYXYP were identified by TLC. The compounds of fatty acids in Perillae oil were determined by CC/MS. Flavones, ginkgolides and ginkgolic acids were determined by HPLC. RESULT: There were good linears relationship between the peak area and concentration, r = 0.999, RSD = 1.2% - 2.5% (n = 5), and recoveries of each composition was above 95%, the contation was stable in 24h. CONCLUSION: This method is proved to be accurate and able to be applied for the quality control of this preparation. |
