In recent years, Opuntia stricta (Cactaceae family) has garnered considerable attention due to its promising nutritional and medicinal properties. This study aims investigate the chemical composition bioactivity of Sicilian fruit pulp seeds. Liquid chromatography–mass spectrometry analysis revealed presence betalain derivatives, especially isobetanin betanin, as main pigments in freeze-dried hydroalcoholic extract. Other constituents, namely, piscidic acid, isorhamnetin-3-O-glucoside, isorhamnetin-3-O-rutinoside, were identified. Linoleic acid (41.95%) was abundant fatty followed by palmitic (19.32%) seed’s fixed oil analyzed gas spectrometry. The antioxidant activity assessed using a multi-target approach 2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing power assay (FRAP), β-carotene bleaching tests. ABTS test showed greater sensitivity action samples with significant half-maximal inhibitory concentrations (IC50) 13.24 14.82 mg/mL for extract pulp, respectively. stricta’s extracts also carbohydrate-hydrolyzing enzyme lipase effect. exhibited highest effect against (IC50 33.54 μg/mL). Collectively, our results contribute characterization this traditionally consumed edible plant suggest use source bioactive compounds useful prevention obesity linked hyperglycemia.
