Abstract

A simple and rapid procedure for the determination of aminophylline, amobarbital, and ephedrine hydrochloride in a capsule preparation is described. Aminophylline and amobarbital are determined simultaneously using differential UV spectrophotometry; ephedrine hydrochloride is determined separately after elution from an alginic acid column with 0.1 N hydrochloric acid.

摘要

本文描述了一种用于测定胶囊制剂中氨茶碱、异戊巴比妥和盐酸麻黄碱的简单快速方法。采用差示紫外分光光度法同时测定氨茶碱和异戊巴比妥；用0.1N盐酸从海藻酸柱上洗脱后分别测定盐酸麻黄碱。
