[Study of some official pharmaceutical preparations in the Sixth Edition of Formule Normales by thin-layer chromatography].
Pharmaceutical preparations--containing aminophenazonum, noraminophenazonum sodium mesylicum, acidum acetylsalicylicum and aethylmorphinium chloratum--official in the VI. Edition of Formulae Normales have been investigated. Simple method for studying decomposition products--which can be carried out in pharmacies and can be followed the quality of products with during their usability--has been developed. The method proving and precluding the presence of decomposition products, respectively by means of preparing dilution sets has been capable of semiquantitative determination of decomposition products. DC Alufolien Kieselgel 60 F254 (Merck) layer was used. Temperature of laboratory was 22-26 degrees C and its relative humidity was 30-40%. Developing solvents were: acetone-ether-water (90:15:12) for aminophenazum; benzene-acetone-90% alcohol-wated (35: 33: 26: 11) for noraminophenazonum sodium mesylicum; methenol-glacial acetic acid-ether-benzene (1: 18: 60: 120) for acidum acetylsalicylicum; dichloromethane-methanol-concentrated ammonia (85: 15: 2) for aethylmorphinium chloratum. Detections were carried out under UV light and by using colour reagents (alcoholic ninhydrine solution for aminophenazonum, dimethylamino-benzaldehyde solution for noraminophenazonum sodium mesylicum). Rf-values of intact and decomposed compounds have been given in figures. Interfering effects of other components of preparations were studied too. These components had different Rf-values or did not react with the colour producing reagents in the applied systems.
