摘要 目的 :测定出血停口服液中没食子酸的含量。方法 :用蒸馏水溶解 ,然后用水饱和正丁醇萃取等步骤制成供试品 ,以薄层扫描法测定 ,λS=2 80nm ,λR=3 5 0nm。结果 :平均回收率为 96.3 6% ,RSD =2 .3 9% ,3批样品中没食子酸的含量分别为 0 .3 8,0 .47,0 .42mg·mL 1。结论 :该方法简便、可行。 Objective:To determine the content of gallic acid in chuxueting oral liquids. Method:The chuxueting oral liquid was dissolved in distilled water, and then extracted with water saturaled n butanol etc. for the preparation of samples. The samples were subjected to gallic acid determination by TLC scanning( λ S =280 nm, λ R =350 nm). Results:The average rate of recovery was 96.36%, RSD =2.39%. The contents of gallic acid in 3 batches of samples were 0.38,0.42 and 0.47 mg·mL 1 respectively. Conclusion:The method is simple, convenient and feasible.
