Methods The UV method for determination of asarone and diprophlline in their mixed solution was established, by which they were assayed when the mixed solution was set at 24 during 6h.

将细辛脑、二羟丙茶碱加入葡萄糖注射液中，混合均匀后，建立细辛脑与二羟丙茶碱混合液紫外分光光度法含量测定方法，分析混合液在室温下(25℃)8 h内2药含量，并观察其pH值、外观、微粒及紫外光谱及峰形变化。

Under certain experimental conditions,the Terbiumbasic Calbonate can be dissolved in aqueous solution of nicotinic acid to yield an Orange Tb Complex, which has a broad characteristic absorption band between, 370—410 nm The autoreduction of the Tb—Complex was studied by means of spectrophotometric method, It was determined by experiments that the reaction order is equal to two and the apparent activation energy of the auto—reduction is equal to 68.4±0,8KJ/mol.

在一定条件下，Tb的碱式碳酸盐可以溶解在烟酸的水溶液中形成橙黄色的络合物，该络合物在390nm波长附近有一宽带特征吸收峰。消光值在0。～1.0范围內与Tb的浓度具有直线关系。分光光度法对Tb自还原反应研究确定：于15℃及烟酸浓度为0.35M时，当pH值小于6.0条件下，随pH值的增加，其自还原速度常数减小，该自还原反应级数为二，反应活化能为68.4±0.8KJ/mo1。
