IN VITRO HYPOGLYCEMIC EFFECTS OF CAESALPINIA BONDUCELLA AND MYRISTICA FRAGRANS SEED EXTRACTS

摘要

The present investigation was undertaken to assess the hypoglycemic potential of Caesalpinia bondu-cella (C.bonducella) and Myristica fragrans (M.fragrans), employing various in vitro techniques. The extracts of seeds of C. bonducella and M. fragrans were studied for their effects on glucose adsorption capacity, in vitro glucose diffusion, in vitro amylolysis kinetics and glucose transport across the yeast cells. It was observed that the plant extracts under study adsorbed glucose and the adsorption of glucose increased remarkably with an increase in glucose concentration. There were no significant (p<0.05) differences between their adsorption capacities. The results of amylolysis kinetic experimental model revealed that the rate of glucose diffusion was found to be increased with time from 30 to 180 min and both the plant extracts demonstrated significant inhibitory effects on movement of glucose into external solution across dialysis membrane as compared to control. Also, the plant extracts promoted glucose uptake by the yeast cells. It was observed that the enhancement of glucose uptake was dependent on both the sample and glucose concentration. C. bonducella extract exhibited significantly higher (p<0.05) activity than the extract of M. fragrans at all concentrations. The results of the study verified the hypoglycemic activity of the extracts of C. bonducella and M. fragrans. However, the observed effects exhibited by the extracts of seeds of C. bonducella and M. fragrans need to be confirmed by using different in vivo models and clinical trials for their effective utilization as therapeutic agents in better management of diabetes mellitus.
