目的:建立大川芎鼻用原位凝胶剂的质量标准。方法:采用TLC法对处方中天麻和川芎进行定性鉴别;并采用HPLC法测定天麻中天麻素,以及川芎中阿魏酸的含量。结果:薄层色谱检出天麻、川芎;天麻素在0.1132-1.698μg内呈良好的线性关系,r=0.9997;平均回收率为100.86%,RSD%=1.79%。阿魏酸在0.02705-0.2705μg内呈良好的线性关系,r=0.9992;平均回收率为98.94%,RSD%=1.42%。结论:该方法简便可行,重现性好,可控制该制剂的质量。
Objective: To establish the quality standard of Rhizoma Chuanxiong nasal in situ gel. Methods: Gastrodiae and Chuanxiong were identified by TLC. The content of gastrodin in Tianma and the content of ferulic acid in Chuanxiong were determined by HPLC. Results: Gastrodiae and Chuanxiong were detected by TLC. Gastrodin showed a good linearity in the range of 0.1132-1.698μg (r = 0.9997). The average recovery was 100.86% and RSD% was 1.79%. Ferulic acid in 0.02705-0.2705μg showed a good linear relationship, r = 0.9992; average recovery was 98.94%, RSD% = 1.42%. Conclusion: This method is simple and feasible, reproducible, and can control the quality of the preparation.
