Derris elliptica (Wall.) Benth, a native medicinal plant, has been used to treat diabetes for centuries; however, comprehensive documentation of its bioactive constituents and therapeutic effectiveness is lacking. In this study, we investigated the phytochemical profile and antidiabetic potential of D. elliptica methanolic leaf extract (DEME) in diabetic Sprague Dawley rats induced with streptozotocin (STZ). In normal rats, acute oral toxicity evaluations were conducted, and in STZ-induced rats, antidiabetic properties were investigated. 14 days of oral administration of standard glibenclamide and the extract at 200 and 400 mg/kg body weight to diabetic rodents. Assessed parameters included blood glucose levels, alterations in body weight, biochemical markers, and histological analysis of the pancreas, liver, and kidney. Numerous phytoconstituents were uncovered through qualitative phytochemical assays, 1H NMR, and 1H–13C HSQC screening. Quercetin was identified by 1H NMR characterization, and a ceramide analogue compound was isolated and partially characterized by 1H NMR. There were no indications of toxicity or mortality. The treatment with DEME significantly (p |
