Abstract
Nettle (Urtica dioica L.) is a plant rich in bioactive active molecules such as phenols, pigments and phytosterols, which have beneficial effects on human health and were the subject of this research. In order to isolate higher yields of mentioned bioactives from nettle, the parameters of accelerated solvent extraction were studied and optimized. In addition, the influence of phenological stage and habitat on the accumulation of bioactive molecules during the growing season was investigated. Furthermore, to protect and stabilize phenolics from nettle leaves, the parameters of encapsulation technique of spray drying were optimized, and it was determined that encapsulation had a positive effect on the bioavailability of phenolic compounds.
Abstract (english)
Kopriva (Urtica dioica L.) je biljka bogata biološki aktivnim molekulama poput fenola, pigmenata i fitosterola koji pozitivno utječu na zdravlje te su predmet ovog istraživanja. Za učinkovitu izolaciju spomenutih komponenata s maksimalnim prinosom iz ekstrakta koprive, ispitani su i optimirani parametri ubrzane ekstrakcije otapalima. Nadalje, ispitan je utjecaj fenotipske faze i staništa na akumulaciju biološki aktivnih molekula tijekom vegetacije. Nadalje, u svrhu zaštite i stabilizacije fenola iz lista koprive optimirani su parametri inkapsulacijske metode sušenja raspršivanjem te je utvrđeno kako inkapsulacija pozitivno utječe na bioraspoloživost fenolnih spojeva.
