چکیده مقاله
The walnut green husk WGH , considered an agricultural byproduct, is a rich source of polyphenolic compounds with notable potential antioxidant, anticancer, anti inflammatory, and antimicrobial activities In this study, the efficiency of ultrasound assisted extraction UAE was compared to conventional maceration for the recovery of phenolic compounds from dried WGH using ethanol water solvent systems 60%, 80%, and 96% The highest extraction yield 18% was obtained using UAE with 96% ethanol The total phenolic content TPC of the extract was 27 68 mg GAE/g of dry extract The DPPH radical scavenging activity was 33 85% at a concentration of 0 08 mg/mL FTIR spectroscopy revealed the presence of functional groups characteristic of polyphenols, including hydroxyl, carbonyl, and aromatic structures These findings confirm the phytochemical richness of WGH and support its potential role as a natural antioxidant source
