Abstract:Preučevali smo primernost šestih različnih zmesi topil - razvijalcev za ločitev enostavnih fenolnih spojin, kot so galna kislina, pirokatehol, floroglucionol, resorcinol, in sorodno spojino katehin s pomočjo tankoplastne kromatografije. Kot najbolj primerna sistema topil za ločitev komponent na stacionarni fazi silikagela na aluminijasti foliji sta se izkazala kloroform -etilacetat - ocetna kislina (prostorninsko razmerje; 50 : 50 : 1) in toluen -acetonitril - mravljična kislina (prostorninsko razmerje; 70 : 30 : 1). Ločitev organskih spojin je bila učinkovitejša v sistemih topil, ki so imeli večji delež organskih topil. Spojine smo vizualizirali s pomočjo dveh reagentov, in sicer z železovim(III) kloridom in z vanilin-žveplovim reagentom.

Title:Thin-layer chromatography of gallic acid, pyrocatehol, phloroglucinol, resorcinol and catechin
Abstract:The suitability of six solvent systems for the thin-layer chromatographic separation of simple phenolic compounds such as gallic acid, pyrocatechol phloroglucinol, resorcinol and related compound catechin were investigated. The most appropriate developing solvent systems for the separation of these organic compounds were chloroform - ethyl acetate - acetic acid (50 : 50 : 1) and toluene -acetonitrile - formic acid (70 : 30 : 1). The best separation of the five organic compounds was achieved using solvents with higher organic content. Detection was carried out using ferric chloride reagent and vanillin-sulphuric reagent.
