用高效液相色谱法同时测定复方氯喘片中三组分的含量。采用μ-BondapakC18柱;流动相为甲醇-0.01mol.L~(-1)磷酸二氢钠(pH=3)(55:45 v/v);紫外检测波长为214 nm;以奈福泮为内标。本法简单、准确。盐酸氯喘、盐酸去氯羟嗪、盐酸溴己胺的平均回收率分别为99.89%、100.21%和99.91%.
Simultaneous Determination of Three Components in Compound Chlorothalcone Tablets by High Performance Liquid Chromatography. The mobile phase consisted of methanol-0.01mol.L -1 sodium dihydrogenphosphate (pH = 3) (55:45 v / v) and the UV detection wavelength was 214 nm. Nefopam was Internal standard. This law is simple and accurate. The average recoveries of chlorhexidine hydrochloride, dechlorophenazine hydrochloride and bromhexine hydrochloride were 99.89%, 100.21% and 99.91%, respectively.
