Abstract
Cilj ovog istraţivanja bio je usporediti različite metode ekstrakcije polifenola iz korijena koprive te prinose fenolnih spojeva u ovisnosi o primijenjenim metodama i uvjetima ekstrakcije UsporeĎivane su Soxhlet ekstrakcija te ekstrakcija superkritičnim CO2 Za Soxhlet ekstrakciju kao otapala su korišteni 96%-tni etanol te n-heksan kako bi se prikazao i utjecaj odabira otapala na prinos ekstrakcije. Soxhlet ekstrakcijom uz primjenu 96%-tnog etanola prinos polifenola iznosio je 14,14%, dok je primjenom n-heksna prinos iznosio 0,768% Ekstrakcija superkritičnim CO2 dala je podjednake prinose kao i Shoxhlet ekstracija n-heksanom.
Abstract (english)
The aim of this study was to compare different methods of polyphenol extraction from the nettle root and to show the influence off applied extraction methods and extraction conditions on the phenolic compounds yield. Soxhlet extraction and supercritical CO2 extraction were compared. To show the effect of different solvent use on the yield of extraction 96% ethanol and n-hexane were used when Soxhlet extraction was conducted. Using ethanol the yield of polyphenols was 14,14% while with n-hexan as a solvent the yield of polyphenols was 0,768%. Supercritical CO2 extraction gave similar results as Soxhlet extraction with n-hexane.
