ABSTRACT
Aims: This study was aimed at investigating the antihyperglycemic effect of a combined extract of Vernonia amygdalinaand croton zabensicuscompare with a hypoglycemic drug, glibenclamide.Methodology:Twenty 20 experimental animals were used (albino rats); the rats were divided equally into four groups of five rats each; namely A (control), B (glibenclamide 10mg/kg body weight), C (synergetic treatment 1000mg/kg body weight), D (synergetic treatment 500mg/kg of body weight). Diabetes was induced intraperitoneal using Alloxan Monohydrate to all the animals and their blood glucose rise above 200mg/dl.Results:It was observed that group B and group C treated with glibenclamide (10mg/kg body weight) and synergetic aqueous extract (1000mg/kg body weight) show significantdecrease in the blood glucose level from 451.75mg/dl to 64.50mg/dl and 339.50mg/dl to 182.50mg/dl respectively compared with group D with 278.25mg/dl to 194.75mg/dl.However, a change was also observed in the body weight of the groups; Group A (Normal control) showed a continuous increase in the body weight, Group B, C and D were observed to have decreased in body weight from induction period, but a steady increase was observed astreatment commences. Conclusion:Hence this combined extract can be used as antihyperglycemic; only that it is slower in remediation compared with the glibenclamide; but without side effect, as may be in the case of most standard drug
