Background: The prevalence of diabetes mellitus is increasing on a global trend. The aim of the present study is to identify the most effective antioxidants and hypoglycemic fraction of Azanza garckeana. Methods: The fractions (nhexane or ethyl-acetate or aqueous) of A. garckeana were administered to the alloxan-induced diabetic rats at doses of 100, 200, and 400 mg/kg for 15 days. Antioxidants activities were evaluated at concentrations of 62.5, 125, 250, and 500 µg/mL using the DPPH scavenging assay. Results: Results revealed that both the hexane, ethyl-acetate, and aqueous fractions exhibited hypoglycemic and antioxidants activities in a dose-dependent manner. The n-hexane fraction demonstrated highest percentage DPPH scavenging effect of 26.34±3.43, 38.44±4.35, 59.34±3.45, and 74.83±5.35 at 62.5, 125, 250, and 500 µg/mL respectively. The ethyl-acetate fraction demonstrated 19.33±2.98, 28.94±3.24, 47.34±2.90, and 57.82±4.54 respectively while the aqueous fraction exhibited the least activities of 12.45±23.45, 18.64±2.94, 27.94±3.89, and 39.43±3.89 at concentrations of 62.5, 125, 250, and 500 µg/mL respectively. In addition, the n-hexane fraction demonstrated the most significant hypoglycemic effect with the highest glucose reduction of 58.97 ±3.45 %, 63.86±5.35 %, and 66.51±4.35 %, ethyl acetate fraction demonstrated glucose reduction of 7.55±0.54%, 21.77±2.35 %, and 29.56±3.46 % while the aqueous fraction demonstrated the least hypoglycemic effect of 9.89±2.67 %, 18.09±3.45 %, and 18.87±3.24 at 100, 200 and 400 mg/kg bw respectively. Conclusion: The n-hexane fraction of Azanza garckeana extract could serve as a reservoir of bioactive agents that could be useful for the development of a new anti-diabetic agent

Acute Study

The present study was aimed to evaluate the root extract fractions of Kyllinga triceps (KT) for their antidiabetic potential on streptozotocin induced diabetes in neonatal rats. Diabetes was induced by a single intraperitoneal injection of Streptozotocin (90mg/kg) to 48±2h old neonatal rats. Effect of root extract fractions (toluene, ethyl acetate, 1- butanol at 50 &100 mg/kg.) were tested for their antihyperglycemic activity by measuring their fasting blood glucose level in diabetic rats at 0,2,4,6,8,12 & 24 h after the treatment. In sub acute study ethyl acetate fraction of KT (EAKT) was administered daily to diabetic rats orally at a dose of 100mg/kg for 28 days. Body weight of the animals and blood glucose level were observed at weekly interval during the study. Cholesterol, triglycerides, insulin, SGPT, ALP, creatinine and total proteins level in serum were also estimated at the initial and after 28 days of the treatment. As the preliminary investigation conducted in our lab on methanolic extract of the roots of KT had showed significant oral glucose tolerance with 200 mg/kg in normal rats. Oral administration of fractions of the plant significantly reduced the fasting blood glucose level in diabetic rats. Among the fractions, EAKT was found to be more effective. Further, in sub-acute study, EAKT, showed a significant anti diabetic activity by reversal of the altered afore said serum biochemical parameters. The results of the study are substantiating the traditional claim of the roots of Kyllinga triceps in the treatment of diabetes with a scope for development of antidiabetic herbal drug from EAKT.   Key words: Antidiabetic activity; Kyllinga triceps; Ethyl acetate fraction; Streptozotocin.

Background/Aims: Trichilia catigua A. Juss., known as “catuaba” in Brazil, has been popularly used as a tonic for fatigue, impotence and memory deficits. Previously, our group demonstrated that the ethyl-acetate fraction (EAF) of T. catigua has antioxidant and anti-inflammatory effects. The present study evaluated the anti-diabetic activity of EAF in type 1 diabetic rats. Methods: Male Wistar rats were divided into four groups (N: non-diabetic group, D: type 1 diabetic group, NC: non-diabetic + EAF group and DC: type 1 diabetic + EAF group). The latter two groups were treated with 200 mg/kg EAF. Type 1 diabetes was induced by intravenous streptozotocin (STZ) injection (35 mg/kg). Starting two days after STZ injection, EAF was administered daily by gavage for 8 weeks. Results: EAF attenuated body mass loss and reduced food and water intake. EAF improved hyperglycaemia and other biochemical parameters, such as alkaline phosphatase (ALP), alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Furthermore, the number of pancreatic β-cells and the size of the islets had increased by β-cell proliferation in the DC group. EAF promoted reduction in kidney tissue damage in STZ-induced diabetic rats by reduction of renal fibrosis. Conclusion: The present study showed that EAF improves glucose homeostasis and endocrine pancreas morphology and inhibits the development of diabetic nephropathy in STZ-induced diabetic rats.
