綜合感冒製劑中,常加入pheniramine maleate, Chlorpheniramine maleate, carbinoxamine maleate, pyrilamine maleate等成分,並常與caffeine併用,利用氣相層析法可同時將上述5種成分分離定性,其分離效果良好,簡單迅速而精確。其層析條件為:玻璃分離管6'×1/4''×2 mm,填充物質3% OV-17 on Chromosor b W, 80~100 mesh,溫度230℃,檢出器:FID。
Pheniramine Maleate, Chlorpheinramine Maleate, Carbinoxamine Maleate and Pyrilamine Maleate are antihistamines useful for allergy and cold, Caffeine anhydrous is CNS exciting agent The simultaneous determination of these ingredients in the cough and cold Pharmaceuticals has been developed by gas liquid chromatography. Chromatographic separation was performed on a 6'×1/4''×2 mm glass chromosorb W, 80-100 mesh, and connected to a flame ion detector ant 260℃. This method has been applied satisfactorily in Syrups, Tablets and Capsules.
