摘要
目的 :为穿心莲片 (穿心莲 )建立一种简便快速的分析方法。方法 :采用流动注射分析法测定脱水穿心莲内酯含量 ,检测波长为 5 4 0nm。结果 :脱水穿心莲内酯在 0 .2～ 1mg·mL-1范围内线性关系良好 ,平均回收率为 10 1.7% ,RSD为0 .7%。进样频率为 12 0样·h-1。结论 :本法简便易行 ,稳定性好 ,可作为该制剂的含量测定方法。
Objective: To establish a simple and accurate method for Chuanxinlian Tablets (Herba Andrographis). Methods:The contents of dehydroandrographolide in Chuanxinlian Tablets was determined by FIA. The detection wavelength was at 540nm. Results:The linear was 0.2～1mg·mL -1 , the average recovery was 101.7%, RSD was 0.7% , respectively. The sampling frequency was 120 samples·h -1 . Conclusion:The method is simple, rapid and stable. It is suitable for the analysis of this preparation.
