trial mixture

METHOD: We detected median lethal dose ( LD 50) of mixture of scopolamine ( SCO) and chlorpromazine ( CPZ) in the different dose to mice and rats by Bliss and Brownlee sequential trial.

方法：用Blis法和Brownle序贯法分别测定不同比例东莨菪碱与氯丙嗪组合成不同比例东氯合剂后对小鼠、大鼠的半数致死量（LD50）。

In the meanwhile, the effects of varied acids for protecting third carbonyl group were investigated. Through the trial and error, the mixture of anhydrous alcohol/ petroleum benzine is the good solvent of target molecule recrystal.

考察了酸性对保护3位羰基的影响，确定了无水乙醇/石油醚是目标分子重结晶的最佳溶剂体系。
