Antidiabetic and enzymatic antioxidant properties from methanol extract of Ficus talboti bark on diabetic rats induced by streptozotocin

ObjectiveTo explore scientifically, the type–I anti-diabetic potential of Ficus talboti bark (FTB).MethodsThe HPLC analysis was carried out to identify the phenolic compounds. Effect of two doses of methanol extract of FTB (100 mg/kg and 200 mg/kg body wt.) was orally administered to STZ (Streptozotocin) induced diabetic rats for 21 days. The various parameters were studied including body weight, fasting blood glucose levels, plasma insulin, lipid profile, glycogen content, total protein, serum enzymes levels, and antioxidant activities in normal, treated and diabetic rats. Histochemical analysis of liver and pancreas were also carried out in normal, treated and diabetic rats.ResultsThe HPLC analysis showed the presence of antidiabetic responsible compounds of Rutin, Quercetin and Kaemfeorl. The treatment group with the extract at two dose levels showed a significant increase in the liver, muscle glycogen and serum insulin level and a significant decrease in fasting blood glucose and serum marker enzyme levels. The total cholesterol and serum triglycerides levels were also significantly reduced and the high density lipoprotein and plasma enzymes level was significantly increased upon treatment with the FTB methanol extract. Histochemical study of pancreas also confirmed the biochemical findings. Acute toxicity studies revealed the non-toxic nature of the FTB methanol extract.ConclusionThe results of the experiments presented here suggest that methanol extract of FTB exerts significant antidiabetic and antioxidant effect in STZ induced diabetic rats.
