Določitev galne kisline, pirokatehola, floroglucinola, resorcinola in katehinas tankoplastno kromatografijo = Thin-layer chromatography of gallic acid, pyrocatehol, phloroglucinol, resorcinol and catechinPoljanšek, Ida ; Vek, Viljem ; Oven, PrimožPreučevali 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.Source: Zbornik gozdarstva in lesarstva = Research reports : forest and wood science & technology. - ISSN 0351-3114 (Št. 95, 2011, str. 3-9)Type of material - article, component part ; adult, seriousPublish date - 2011Language - slovenianCOBISS.SI-ID - 3256486
