摘要
将岭回归吸光光度法 (LHG)应用于感冒液中扑热息痛、扑尔敏、咖啡因、愈创木酚甘油醚和对氨基酚等五组分含量的同时测定 ,运用VB语言进行程序设计。试验结果表明 ,该法对样品各组分的平均回收率在 97.9%～ 10 3.3%之间 ,样品不经分离即可测定 。
Five main components i.e. acetaminophen, p -aminophenol, caffeine, chlorphenamine maleate and guaifenesin, in cough syrup are determined simultaneously by the ridge regression-UV-absorptiophotometry using a computer program with VB language. The difficulty of overlapping of absorption spectrums of these five compounds are overcome by this procedure. Recoveries obtained in the determination of these compounds are found in the range of 97.9%～103.3%. The analysis can be carried out easily and rapidly without any separation, and satisfactory results are obtained.
