【摘要】 目的:制定喉咽清含片的质量标准。方法:采用薄层色谱法鉴别土牛膝、马兰草、天名精,用薄层扫描法测定本品中主要化学成分齐墩果酸的含量。双波长反射法锯齿扫描,λS=520 nm,λR=700 nm,SX=3;灵敏度:中;展开剂:环己烷-三氯甲烷-醋酸乙酯(20:5:8)。结果:本方法能准确对土牛膝、马兰草、天名精进行定性鉴别;齐墩果酸在1.008~6.048μg范围内呈良好线性关系。结论:本方法快速、简便、准确、重现性好,可作为喉咽清含片的质量标准。更多还原

【Abstract】 Objective: To establish the quality standard for Houyanqing buccal tablet(HBT).Methods: Twotooth achyranthes root,Jerba kalmeridis and common carpesium root and leaf in HBT were identified by TLC.Oleanolic acid in HBT was also determined by TLC.Scanning with double wavelength reflectometry,λS=520 nm,λR=700 nm,SX=3;sensitivity was middle with developing agent of hexamethylene-trichloromethane-ethyl acetate(2058).Results: Twotooth achyranthes root,Jerba kalmeridis and common carpesium root and leaf could be differentiated qualitatively by TLC.The linear range of oleanolic acid was 1.008～6.048 μg.Conclusion: The method is rapid,simple and accurate with good reproducibility,can be used as quality standard of HBT.更多还原
