The purpose of the study is in silico molecular docking of principal components of TEO, REO, and GEO followed by in vitro validation of inhibition of α-amylase activity. For docking Cb-dock2 tool was utilized. Ligand-Protein 2-D interactions were also studied. From the perspective of human health, in silico ADMET pharmacoinformatic features (Physicochemical, Lipophilicity, Medicinal Chemistry, Druglikeness, Absorption, Water Solubility, Distribution, Metabolism, Pharmacokinetics, Excretion) have prospected. Using α-amylase, wet lab validation was carried out. 2, 2-Diphenyl-1-picryl hydrazyl (DPPH) radical inhibition assay was conducted to ascertain the antioxidant role of all EOs. Docking investigation demonstrated the effective binding of all the ligands with the α-amylase. The interaction results imply that the enzyme-ligand complexes form hydrogen, hydrophobic, and other interactions. In silico ADMET examination disclosed that all the ligand molecules have no toxic effect and acceptable absorption, as well. Further, TEO, REO, and GEO have dose-dependent inhibitory action against α-amylase. All EOs depicted good antioxidant potential. Kinetic analysis revealed that TEO, REO, and GEO competitively inhibited α-amylase. It was concluded that these substances can function as model molecules for the synthesis of novel anti-diabetic substances.enα-amylasediabetesessential oilmolecular dockingAcarboseArticle
