Application of deep eutectic solvents in extraction of natural products

Ovaj pregled ističe neka od jedinstvenih svojstava eutektičkih otapala te primjene istih u ekstrakciji prirodnih produkata. Ona su, kao novi tip ekološki prihvatljivih otapala, privukla povećanu pažnju u kemiji u svrhu ekstrakcije i odvajanja ciljanih spojeva iz različitih uzoraka. Rad daje sažeti pristup primjene eutektičkih otapala u svrhu ekstrakcije kafeina iz kave, hesperidina i limonena iz naranče te miricetina i amentoflavona iz Japanskog čempresa. Eutektička otapala korištena u eksperimetnu su kolin klorid-etilen glikol i kolin klorid glicerol. Analiza uzoraka na UV/VIS i FTIR uređajima dokazala je uspješnost ekstrakcije pomoću navedenih otapala.This review highlights some of the unique properties of eutectic solvents and their application in the extraction of natural products. They are, as a new type of environmentally friendly solvents, attracted increased attention in chemistry for the purpose of extraction and separation of target compounds from different samples. The work provides a concise approach to the application of eutectic solvents for the purpose of extraction of caffeine from coffee, hesperidin and limonene from orange and myricetin and amentoflavone from Japanese cypress. Eutectic solvents used in the experiment are choline chloride-ethylene glycol and choline chloride glycerol. Analysis of the samples on UV / VIS and FTIR devices proved successful extraction using these solvents
