美国药典对茶碱的分析方法中所采用的流动相中的乙睛对操作者毒害大，且使用代价大，本法在参考美国药典方法USP法的基础上使用毒性小、代价低的甲醇代替乙循建立了茶碱的分析方法（HPLC法），实验效果良好。三仪器与试剂三．且仪器岛津LG6A高效液相色谱仪，SPry6AV紫外检测器
The United States Pharmacopoeia on theophylline analysis method used in the mobile phase of the acetonitrile is toxic to the operator and the use of large, the law in reference to the United States Pharmacopoeia USP method based on the use of less toxic, lower cost methanol instead B by establishing a theophylline analysis method (HPLC method), the experimental effect is good. Three instruments and reagents three. And instrument Shimadzu LG6A high performance liquid chromatography, SPry6AV UV detector
