  • Opuntia dillenii has been widely used in traditional medicine for various health conditions. This study examined the chemical composition of aqueous extracts from the plant's juice and peel and evaluated their effects on pancreatic α-amylase, lipase, and intestinal α-glucosidase enzymes, as well as their antihyperglycemic properties in vivo. Using High-Performance Liquid Chromatography with a Photodiode Array Detector (HPLC-DAD), significant variations in the composition were found between the plant's juice and peel, Key compounds included gallic acid, vanillic acid, p-coumaric acid, 3-hydroxy flavone, quercetin, cinnamic acid, kaempferol, and flavone. p-coumaric acid was highest in the juice (298.71±0.43 mg/100g) and peel (38.18±1.08 mg/100g), while flavone was higher in the peel (120.03±0.26 mg/100g). The extracts significantly inhibited pancreatic α-amylase and intestinal α-glucosidase in vitro, with confirmed in vivo effects reducing hyperglycemia in both healthy and diabetic rats. No toxicity was observed until the dose of 4000 mg/kg body weight. Molecular docking models showed that the plant's phytochemicals interacted with pancreatic enzymes more effectively than the drug acarbose. These findings highlight Opuntia dillenii's potential as a source of natural compounds with therapeutic properties, warranting further exploration.
