目的:建立通塞益脑口服液的质量控制方法。方法:采用TLC法鉴别方中的地龙、川芎、延胡索;采用HPLC法测定通塞益脑口服液中阿魏酸含量。结果:在TLC色谱中可检出川芎、地龙、延胡索的特征成分斑点;阿魏酸在15.28～152.8mg·L-1呈良好的线性关系(r=0.999 7),平均加样回收率为99.38%(RSD 1.11%,n=6)。结论:所建立的方法能够准确可靠的进行定性、定量检测,重复性好,可作为通塞益脑口服液的质量控制标准。
Objective: To establish a quality control method for Tongsai Yinao oral liquid. Methods: Dioscorea bulbata, Chuanxiong rhizome and corydalis extract were identified by TLC. The content of ferulic acid in Tongsai Yinao oral liquid was determined by HPLC. Results: The Chlamydomonas reinhardtii, Rhizoma Corydalis and Rhizoma Corydalis could be detected by TLC. The ferulic acid had a good linear relationship (r = 0.999 7) between 15.28 and 152.8 mg · L-1, the average recovery was 99.38% (RSD 1.11%, n = 6). Conclusion: The established method can accurately and reliably carry out qualitative and quantitative tests with good repeatability and can be used as quality control standard for Tongsai Yinao Oral Liquid.
