安痛定注射液系氨基比林、安替比林和巴比妥的复方制剂,贵州省药品标准所收载的含量测定方法,操作繁琐,误差较大,本文根据线性规划原理,借助于微机,采用对偶单纯形法解线性规划,直接测定了安痛定注射液中氨基比林、安替比林和巴比妥的含量。 1.仪器与试药 751G型分光光度计,TRS-80型电子计算机,氨基比林、安替比林、巴比妥(均符合中国药典90年版),其他试剂均为分析纯。 2.测试溶剂的选择: 据报道,巴比妥在不同酸碱度的溶液中,其吸收光谱随电离级数不同而异,在酸性溶液中不电离,几乎无显著吸收;在PH9.9的
Antongding injection of aminopyrine, antipyrine and barbiturate compound preparation, Guizhou Province, the pharmaceutical standards contained content determination method, cumbersome operation, the error is large, this paper according to the principle of linear programming, with the help of computer , The dual simplex method was used to solve the linear programming, and the contents of aminopyrine, antipyrine and barbiturate in the Antongding injection were directly determined. 1. Instruments and reagents 751G spectrophotometer, TRS-80 electronic computer, aminopyrine, antipyrine, barbiturate (all in line with the Chinese Pharmacopoeia 90-year edition), the other reagents were of analytical grade. 2. Test the choice of solvents: It is reported that in different pH solutions of barbiturates, the absorption spectrum varies with the ionization series varies in the acidic solution is not ionized, almost no significant absorption; at pH9.9
