摘　　要：目的:建立清火栀麦片中脱水穿心莲内酯的含量测定方法。方法:双波长薄层扫描法。结果:脱水穿心莲内醋在1.025～5.125μg有良好线性关系,平均回收率101.5％,RSD=2.04％。结论:方法简便,快速,准确,重现性好。Objective: To determine the content of 14 -deoxy-11,12 -didehydroandrographolide in Qinghuozhitnai Tablets by TLC -Scanning. Method: 14 -deoxy-11,12 -didehydroandrographolide was determined by dual wavelength TLC-Scanning. Result :The calibration curve was linear within the range of 1. 025-5.125 ng of 14 -deoxy-11,12 -didehydroandrographolide. The average recovery rate and RSD were 101. 5% and2.04%(n= 5). Conclusion; The method is simple,rapid,accurate and reproducible.
