20.500.12556/DKUM-64205 PRIDOBIVANJE KLOROFILA IN DERIVATOV KLOROFILA EXTRACTION OF CHLOROPHYLL AND CHLOROPHYLL DERIVATIVES Diplomska naloga obravnava pridobivanje čistega klorofila iz koprive. Z metodo ekstrakcije odstranjujemo iz trdnih in tekočih zmesi topne komponente s topilom. Uporabljamo ekstrakcijo iz trdnih zmesi (Soxhletov ekstraktor), ekstrakcijo iz raztopin in superkritično ekstrakcijo. Kvalitativno določimo rezultate s spektroskopijo in papirno kromatografijo. Izračunamo tudi stroške postopkov za pridobivanje klorofila in njegovih derivatov. Na osnovi dobljenih rezultatov in izračunanih stroškov izberemo najboljši postopek za pridobivanje klorofila in njegovih derivatov. The present thesis considers the production of the pure chlorophyll from nettle. With the extraction method the soluble components were removed from solid and liquid mixtures with a solvent. We used the extraction of the solid mixture (Soxhlet apparatus), the extraction of the solution and the supercritical extraction. Qualitative results were determined by paper chromatography and spectroscopy. We calculated also the costs of processes for the production of chlorophyll and its derivatives. Based on the results obtained and calculated costs the best method for the production of chlorophyll and its derivatives is chosen. kopriva naravna barvila (klorofil karotenoidi) ekstrakcija iz trdnih zmesi ekstrakcija iz raztopin rotavapor UV spektrometer papirna kromatografija nettle natural coloring (chlorophyll carotenoids) extraction from solid mixture extraction from solutions evaporator UV spectrometer paper chromatography true true false [J.
