All the extractions were performed using a solid/liquid ratio of 1/20 (m/v). The extraction solvent was ethanol/water mixture in a proportion of 90/10 (v/v). After extraction, the solvent was separated from the matrix by filtration to vacuum using a filter paper. The extract was concentrated until dryness by solvent evaporation under vacuum (Laborota 4001, Heidolph, Germany).
