系数倍率法测定脑宁片含量

DETERMINATION OF AMIDOPYRINE AND CAFFEINE COMPOUND TABLETFS BY K-RATIO SPECTROPHOTOMETRY

摘要: 脑宁片为镇痛药,每片含氨基比林150mg、咖啡因40mg、甘油磷酸钙35mg。天津市地方标准采用容量分析法,操作较繁、费时。鉴于甘油磷酸钙无紫外吸收,但氨基比林、咖啡因紫外吸收光谱相互重叠的特点,本文利用系数倍率法消除它们之间的相互干扰,进行含量测定,操作简易快速。自编的BASIC程序,在计算机输出结果的基础上最

Abstract: In order to eliminate the interference of coexisting ingredients in Amidopyrine and Caffeine Compound Tablets without any separation, amido- pyrine and caffeine were determined by K-Ratio spectrophotometry with alcohol as solvent by using 751-G spectropho
