Effect of different fractions of Hibiscus rosa sinensis leaf extract on islets of Langerhans and antioxidant activity in non-obese diabetic (NOD) mouse

The present investigation was undertaken to study the effect of Hibiscus rosa sinensis leaf extract fractions on islets of Langerhans, total antioxidant activity in non-obese diabetic (NOD) mouse. Two sets of experiments were conducted. First experiment was designed to test the hypoglycemic properties of different isolated fractions. Five fractions were screened for hypoglycemic property. Fractions F3, F4 and F5 showed hypoglycemic in NOD mice. Second set of experiment was conducted to assess the effects of above fractions on the diameter of islets of Langerhans and on the â-cells number and total antioxidant capacity (TAC). All the fractions had a significant effect in the enhancement of diameter of islets of Langerhans and the â-cell number and antioxidant active (total antioxidant capacity) compared with control NOD mice

Antidiabetic properties of <i>Hibiscus rosa sinensis </i>L. leaf extract fractions on non-obese diabetic (NOD) mouse

24-29On fractionation the ethanolic extract of H. rosa sinensis leaves, 5 fractions were obtained. Of these, fraction-3 (F3) and fraction-5 (F5) were chosen for detailed investigation on non obese diabetic (NOD) mouse to study anti-diabetic properties because they were more active than others. Serum glucose, glycosylated hemoglobin, triglyceride, cholesterol, blood urea, insulin, LDL, VLDL, and HDL were estimated. Both fractions F3 and F5 on oral feeding (100 and 200 mg/kg body weight) demonstrated insulinotropic nature and protective effect in NOD mice. These fractions may contain potential oral hypoglycemic agent
