Optimal chromatographic separation of the analytes in minimal analysis time (8 min) was achieved on a Luna C18 150 % 4.6 mm column using a mixture of acetonitrile, tetrahydrofuran and water (50:45:5, v/v/v). The described reversed phase HPLC method is the first published for quantification of these five fat-soluble vitamins and coenzyme Q10 within a single chromatographic run. The method was further applied for quantification of the analytes in selected liquid and solid dosage forms, registered as nutritional supplements and prescription medicines, which confirmed its suitability for routine analysisRazvili in validirali smo natančno, tono in hitro HPLC-UV metodo za sočasno vrednotenje lipofilnih vitaminov (vitamin D3, E-acetat, K1, beta-karoten, A-palmitat) in koencima Q10. Optimalno kromatografsko ločbo analitov v kratkem času analize (8 min) smo dosegli na koloni Luna C18 150 X 4,6 mm z uporabo mobilne faze: acetonitril, tetrahidrofuran in voda (50: 45: 5, v / v / v). Opisana reverznofazna HPLC-UV metoda je prva objavljena analizna metoda za sočasno vrednotenje izbranih lipofilnih vitaminov in koencima Q10. Metodo smo nadalje uporabili za vrednotenje teh analitov v izbranih zdravilih in prehranskih dopolnilih, v tekočih in trdnih farmacevtskih oblikah ter tako potrdili njeno primernost za rutinsko uporaboTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaSlovensko kemijsko društvo
