Characterization of electrospun Aronia melanocarpa fruit extracts loaded polyurethane nanoweb
Abstract In this study, Aronia melanocarpa fruit was extracted with ethanol, distilled water (pH 7), acidified distilled waters (at pH 5 and 3) as the solvent, the total polyphenol content, total flavonoid content, and anti-oxidant activity of the extracts were analyzed. Then, we investigated the po...
