Evaluation of molecular docking analysis of isolated phytoconstituents from Barleria buxifolia and Barleria cuspidata. Phytoconstituents such as quercetin-3-O-β-D-glucoside, 7-methoxy diderroside, β-sitosterol-β-D-glucoside and luteolin 7-O-glucoside were docked with antidiabetic drug target proteins such as pyruvate dehydrogenase kinase, human 11-betahydroxysteroid dehydrogenase (HSD1), glucagon-like peptide-1 and glycogen synthase kinase – 3 using Autodock 4.2 software
