Characterisation of phenolic compounds was carried out by Folin-Ciocalteau method. Antioxidant activity of Chokeberry (Aronia) and Elderberry products were determined using 2,2-diphenyl-2-picrylhydrazyl (DPPH). All extraction runs were carried out at constant extractive parameters chosen previously - temperature, sample particle size, extraction manner. All analyses were performed spectrophotometrically. This study focuses on the convectional extraction - particularly conventional solid-liquid extraction (conducted via magnetic stirrer) of pre-dried Chokeberry and Elderberry. An investigation of total polyphenol contents (TPC) and total antioxidant capacity (TAC) were done. Extraction takes place at a pre-selected duration of 100 minutes. The extraction was examined with 5 solvents: aqueous solution of ethanol with concentration (20 vol. %; 50 vol. %; 80 vol. % and 96 vol. %) and distilled water. The temperature was kept constant at 40oC.enArticle
