Abstract
The paper addresses the case of Daucus carota L. extract, obtained by liquid-solid extraction methods (heat reflux, Soxhlet extraction and maceration) using ethanol solution of different concentrations as extraction reagent. The performance of the extraction methods was assessed based on the extraction yield value. The extracts obtained were characterized qualitatively by HPLC and quantitatively by determining the content of polyphenols and flavonoids. Two O/W emulsions based on Daucus carota L. extract were also prepared and were preliminarily characterized in terms of stability and homogeneity.
