One of the most important bioactive properties of flavonoids is their antioxidant effect. There was significant difference between phenolic contents of the extracts using two mentioned solvents in both cultivars. The optimal conditions were found to be 59 C, 60% (v/v) ethanol, and extraction time of 30 min. The increased . The effect of the extraction methods employed on phenolic compounds for one of the analyzed plant is presented in Fig.
Plant material (10 g) was reduced to a fine powder and extracted in a Soxhlet extractor (90C for 24 h) with 200 ml of 70% aqueous methanol (v/v) acidified to pH 2 with some concentrated HCl drops. The flavonoids are compounds synthesized by plants, and they have properties such as antioxidant, anticancer, anti-inflammatory, and antibacterial, among others. It is worth stating here that, to date, no consensus has been reached on a standard solvent for the extraction of phenolic compounds from plants. Extraction of phenolic compounds from green walnut fruits in different solvents Acta agriculturae Slovenica, 93 - 1, maj 2009 13 compounds were extracted in both cultivars.
