脉路通片内含潘生丁和阿斯匹林。因阿斯匹林的存在使潘生丁的含量测定受到干扰。本文报告了采用日立200—20型单波长双光束分光光度计,按双波长法选择λ_2=288nm,λ,=260nm,样品不经分离,直接测定潘生丁的含量,得到满意的结果。方法简单、准确,用给出的条件,测定八份样品,平均回收率99.2±0.5%。 Pulse Road contains dipyridamole and aspirin. The determination of dipyridamole was interrupted by the presence of aspirin. In this paper, the Hitachi 200-20 single-wavelength dual-beam spectrophotometer was used to determine the content of dipyridamole without any separation by the method of dual wavelength λ_2 = 288nm, λ, = 260nm. The results were satisfactory. The method is simple and accurate, with the given conditions, the determination of eight samples, the average recovery rate of 99.2 ± 0.5%.
