Abstract
U ovom radu je bila provedena ultrazvučna ekstrakcija raznih polifenola iz širokolisnog trputca (Plantago major L.) mijenjajući uvjete ekstrakcije. Mijenjana je temperatura, snaga ultrazvuka te sastav ekstrakcijskog otapala. Ekstrakcijsko otapalo je bilo priređeno s glicerolom, vodom i mliječnom kiselinom varirajući udio pojedinih sastavnica. Rezultati su pokazali varijabilnost u uspješnosti i iskorištenju ekstrakcije ovisno o sastavu ekstrakcijskog otapala i strukturi promatranog polifenola. Kod većine spojeva je ekstrakcija bila uspješnija uz veći udio glicerola i mliječne kiseline te povećanjem temperature i snage ultrazvuka. Iznimke su bile flavonoidi i feniletanoid verbaskozid kojima je pogodovao manji udio glicerola te iridoid aukubin koji je osjetljiv na kiseline i visoku temperaturu.
Abstract (english)
In this study, ultrasonic extraction of various polyphenols from broad-leaved plantain (Plantago major L.) was carried out by variation of extraction parameters. The temperature, ultrasound power and composition of the extraction solvent were changed. The extraction solvent was prepared with glycerol, water, and lactic acid, varying the proportion of individual components. The results show variability in the success and utilization of the extraction depending on the composition of the extraction solvent and the structure of the observed polyphenol. For most compounds, the extraction was more successful with a higher proportion of glycerol and lactic acid and by increasing the temperature and ultrasound power. The exceptions were flavonoids and phenylethanoid verbascoside, which benefited from a lower proportion of glycerol, and iridoid aucubin, which is sensitive to acids and high temperatures.
