二羟丙茶碱

细辛脑与二羟丙茶碱注射液配伍稳定性研究

Studies on compatible stability between asarone injection and diprophylline injection

在新的最佳工艺条件下二羟丙茶碱缩合收率达到了86.03%，较原生产工艺提高5%。

Under the above technology conditions , the yield of diprophylline reached to 86.03 % , and was higher 5 % than before .

通过对固定相、流动相选取，色谱条件的确定，建立了可对茶碱、二羟丙茶碱进行同时检测的高效液相色谱分析方法。

After selecting stationary phase and Mobile phase , and definite chromatographic condition , the analysis method for diprophylline and Theophylline by HPLC was established .
