Determination of the most efficient extraction method and solvents for the isolation of phenolic compounds from species Veronica polita L. and Veronica chamaedrys L.

Rod Veronica pripada porodici Plantaginaceae te broji preko 200 vrsta. Široka rasprostranjenost, ali i razni dobrobiti za zdravlje, koje dolaze ponajprije od sekundarnih metabolita, stavljaju ovaj rod u centar raznih medicinskih, farmakoloških i bioloških istraživanja. Glavni cilj ovog rada bio je istražiti koje metode ekstrakcije te koja otapala su najučinkovitija za ekstrakciju fenolnih spojeva iz vrsta Veronica chamaedrys L. i Veronica polita L. Od metoda ekstrakcije ispitivane su: maceracija, dekokcija te ekstrakcija ultrazvučnom kupelji na 25 ⁰C i 40 ⁰C. Za otapala korišteni su: destilirana voda, 80%-tni etanol te metanol.The genus Veronica belongs to the Plantaginaceae family and has over 200 species. Wide distribution but also various health benefits, which come primarily from secondary metabolites, put this genus at the center of various medical, pharmacological and biological research. The main goal of this work was to investigate which extraction methods and which solvents are the most effective for the extraction of phenolic compounds from the species Veronica chamaedrys L. and Veronica polita L. The examined extraction methods are: maceration, decoction and extraction with an ultrasonic bath at 25 ⁰C and 40 ⁰C. The following solvents were used: distilled water, 80% ethanol and methanol
