Abstract
The present study evaluated the antidiabetic potential of Butea monosperma Lam. Kuntze (Fabaceae) leaves and the stem bark using various in vitro techniques. The samples were studied for their effects on glucose adsorption, diffusion, amylolysis kinetics, enteric enzymes and glucose transport across yeast cells. Both the samples adsorbed glucose and the adsorption of glucose increased with increase in glucose concentration. The samples also inhibited movement of glucose across the dialysis membrane to varying degree in both glucose diffusion and amylolysis kinetic experiment models. B. monosperma leaves inhibited α-amylase, α-glucosidase and sucrase enzymes in succession to varying degrees, whereas the bark inhibited only α-amylase to a significant extent and slightly activated α-glucosidase and sucrase enzymes. The extracts of both leaves and bark promoted glucose uptake by yeast cells compared to control. Enhancement of glucose uptake was dependent on both the sample and glucose concentration. It was directly proportional to the sample concentration and inversely proportional to the molar concentration of the glucose. From the results of the study, it is inferred that, B. monosperma leaves and bark possesses antidiabetic activity. However, these effects need to be confirmed using in vivo models and clinical trials for its effective utilization as therapeutic agents.
