The present investigation aims to examine the diabetic potential of the plant Ficus racemosa in normal and alloxan induced diabetic rats. The bark extract with water, petroleum ether and with alcohol were screened for blood glucose lowering activity and the alcoholic extract having better therapeutic potential was prepared through Soxhlet extraction for further study. Alcoholic and aqueous extract of bark of Ficus racemosa at a dose of 400 mg/Kg was given to normal and alloxan induced diabetic rats and the blood samples taken from the retero-orbital plexus vein were analyzed for blood glucose level as per standard protocol with available kits through Auto-analyzer. The comparison of blood sugar level as per model schedule showed that in normal group the ethanolic extract, at a dose of 400 mg/Kg intra-peritoneal, the blood glucose lowering 28.66 % while in aqueous extract given group it was 25.90 %. In alloxan induced diabetic rats decrease in blood glucose level in aqueous and ethanolic extract group was found to be 27.01 % and 45.03 % respectively. In conclusion, the ethanolic extract of Ficus racemosa reflected anti-diabetic potential through its glucose lowering activity in experimental animals. It supported the folklore claim of anti-diabetic activity of the plant.
The anti-inflammatory and analgesic activities of the ethyl acetate (EAFSM) and n-butanol (NBFSM) fractions of the alcoholic extract of S. mangifera bark were evaluated using carrageenan-induced rat paw edema and by the tail-flick method in rats. The radical scavenging activity of the ethanolic extract, aqueous extract and fractions was determined with the DPPH radical scavenging capacity assay. Two fractions of the alcoholic extract, EAFSM and NBFSM, at doses of 75, 150, 300 mg/kg b.w. administered orally, showed a significant reduction in paw volume when compared with the respective control group challenged by carrageenan. Different doses of extract fractions also showed a significant prolongation of the tail-flick latency of the rat (P<0.01). Different concentrations of alcoholic, aqueous extracts and fractions of alcoholic extract showed significant free radical scavenging capacity against DPPH generated free radicals
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
