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</dc:description><dc:description xml:lang="sl">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</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-NXQI2ZLR"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-NXQI2ZLR" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-NXQI2ZLR/7c244da1-f013-4d5c-a5f9-247491e71112/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Biotehniška fakulteta</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-NXQI2ZLR/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-NXQI2ZLR" /></ore:Aggregation></rdf:RDF>
