Diabetes is a prevalent metabolic disorder associated with various complications. Inhibition of α‐glucosidase and α‐amylase enzymes is an effective strategy for managing non‐insulin‐dependent diabetes mellitus. This study aimed to investigate the antioxidant and antidiabetic potential of Ormocarpum cochinchinense leaf through in vitro and in silico approaches. The methanol extract exhibited the highest phenolic and flavonoid content over solvent extracts aqueous, acetone, hexane and chloroform, same has been correlating with strong antioxidant activity. Furthermore, the methanol extract demonstrated significant inhibitory effects on α‐amylase and α‐glucosidase enzymes, indicating its potential as an antidiabetic agent. Molecular docking analysis identified compounds, including myo‐inositol, with favorable binding energies comparable to the standard drug metformin. The selected compounds displayed strong binding affinity towards α‐amylase and α‐glucosidase enzymes. Structural dynamics analysis revealed that myo‐inositol formed a more stable complex with the enzymes. These findings suggest that O. cochinchinense leaf possesses antioxidant and antidiabetic properties, making it a potential source for developing therapeutic agents.
