本文报道了胶囊及血浆中双氢氨苄青霉素的一种新的紫外分光光度测定法。本法原理系将抗生素进行酸牲水解,然后测定水解产物的吸收度,从而间接测得双氢氨苄青霉素的含量。文中还介绍了分离,鉴定,模拟胶囊及商品胶囊的分析和回收率研究。同时用直流极谱法分析了血浆。 This article reports a new UV spectrophotometric assay of ampicillin in capsules and plasma. The principle of this law will be acid hydrolysis of antibiotics, and then determine the degree of absorption of hydrolysates, which indirectly measure the content of ampicillin. The article also introduced the separation, identification, simulation and commercial capsule analysis and recovery studies. Plasma was also analyzed by direct current polarography.
