The fruits of Pistacia integerrima (PI), Withania coagulans (WC) and Withania somnifera (WS) have been reported for their medicinal values. The aim of the present study was to compare the glucose lowering activities of the fruit extracts of these three medicinal plants in glucose induced non-diabetic hyperglycemic and normal rabbit models. During the first phase of experiments, the effects of oral administration of 70% methanol extract of each plant fruit (600 mg/kg body weight) and glibenclamide (5 mg/kg body weight) were studied on the glucose level of glucose induced hyperglycemic rabbits, while in the second phase of experiments, the effects of each fruit extract (600 mg/kg body weight) and glibenclamide (5 mg/kg body weight) were assessed on the glucose level of normal rabbits. Among the three fruit extracts, maximum reduction in the blood glucose level was caused by the PI extract (P ˂0.05). The glucose lowering activity of the PI extract was greater than that of the standard, glibenclamide (5mg/kg), during the first phase of experiments. However during the second phase of experiments the hypoglycemic effect of the PI extract was comparable to that of the standard, glibenclamide (5mg/kg). In conclusion the present study reveals that the 70% methanol extract of Pistacia integerrima fruit can decrease glucose level significantly in glucose induced non-diabetic hyperglycemic and normal rabbit models.

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.

Objective: To evaluate the anti-diabetic and anti-diarrheal activity of methanol extract of Flemingia stricta Roxb. (Fabaceae) leaf.Methods: In anti-diabetic study, the extract was administered to alloxan-induce diabetic mice at two concentrations (200mg/kg and 400mg/kg body weight) for acute (12 hours) and prolong treatments (15 days) and blood glucose levels (Blood glucose level) of diabetic mice were monitored at intervals of hours and days throughout the duration of treatment. Antidiarrheal test was conducted by castor oil induced diarrhea and enteropooling as well as intestinal motility in mice at three different concentration (100mg/kg, 200mg/kg and 400mg/kg body weight).Results: Treatment of alloxan induce diabetic mice with the extract caused a significant reduction in fasting blood glucose level of the diabetic mice both in acute (12 hours) and prolong treatment (15 days) and it was determined that the extract at both concentration (200mg/kg and 400mg/kg) showed the significant (P<0.05) hypoglycemic effect in comparison to the standard drug Metformin (10mg/kg). In the case of castor oil induced diarrheal test, enteropooling test and gastrointestinal motility test, the extract of F. stricta at 100mg/kg, 200mg/kg and 400mg/kg has given significant effect (P<0.05) in comparing to standard drug Loperamide (5mg/kg). Conclusion: These result suggested that the methanol extract of F. stricta Roxb. possess promising anti-diabetic effect on alloxan-induced mice and significant antidiarrheal effect on castor oil induced diarrheal mice.

AbstractBackground:Tamarindusis a monotypic genus and belongs to the subfamily Caesalpinioideae of the family Leguminosae (Fabaceae),Tamarindus indicaL., commonly known as Tamarind tree is one of the most important multipurpose tropical fruit tree species in the India, Sudan, Nigeria, Bangladesh and entire subcontinent.Methods:Hydroethanolic seed coat extract ofTamarindus indica(HETI) was assessed for presence of phytoconstituents and selection of optimum dose through acute and sub acute toxicity study. The single and multidose (14 days) study were conducted to evaluate antidiabetic potential of HETI in alloxan induced rats via determine of blood glucose level, body weight, hematological profile, extra-pancreatic glucose utilization of isolated rat hemi-diaphragm as well as histopathology of rat pancreas.Results:Phytochemical analysis of HETI showed the presence of polyphenol like flavonoids. Single and multidose of HETI significantly (p<0.05; p<0.001) reduced blood glucose level in normoglycaemic, glucose loaded and alloxan induced hyperglycaemic animals. HETI exerts the protective effect on pancreatic β-cells as per results obtained from histopathology of animals. Moreover, HETI increased glucose uptake in isolated rat hemi-diaphragm and prevents decrease in body weight along with recovery of altered hematological parameters.Conclusions:The study revealed that HETI have potent hypoglycaemic action by virtue of its phytoconstituents and it can be used as a herbal medicine for diabetes.

Aims: To investigate the effect of food blends (plantain, soybean and ginger) on the blood glucose, lipid profile and haematological indices on streptozotocin induced diabetic rats. Methodology: A total of 35 rats of mean body weight 219.07 g separated into7 groups (5 per group) where induced by a single intraperitoneal (I.P) injection of streptozotocin (0.1 g dissolved in 5 ml of freshly prepared sodium citrate buffer 0.1 M, pH 4.5) at a dose of 40 mg/kg body weight after fasting for 12 hours and fed with flours/blends. The flours were produced from plant materials for different treatments/blends (blend A=100% unripe plantain, B=80% unripe plantain, 14% soybean, 6% ginger, C=70% unripe plantain, 26% soybean, 4% ginger, D= 60% unripe plantain, 38% soybean, 2% ginger, E= 50% unripe plantain, 50% soybean) and the phytochemicals and minerals content were determined. Blood glucose was determined at 5 days interval for 25 days. Diabetes was confirmed in rats with blood glucose concentrations >200 mg/dl. After 25 days rats were anaesthetized with chloroform vapour and blood samples collected by cardiac puncture for haematology and lipid profile determination. Results: The results showed that unripe plantain, soya beans and ginger in adequate proportion(C=70% unripe plantain, 26% soybean, 4% ginger or D= 60% unripe plantain, 38% soybean, 2% ginger) could help to reduce blood glucose, improve haematological parameters and lipid profile. Significant reduction was observed in the blood glucose level of rats fed blends C and D from 286 to 85 mg/dl and 307 to 90 mg/dl respectively at the end of experiment. These results also demonstrated that the inclusion of ginger at 6% causes rise in blood glucose level. Total cholesterol (TC) increased in all the blends. However, the lowest concentration of TC was observed in blends C and D. The highest packed cell volume (60%) and Haemoglobin (20 g/dl) level observed in rats fed blend C was significantly higher than the normal control fed conventional feeds. The increase in packed cell volume (PCV) (50%) and Hb (17 g/dl) in diabetic rats demonstrated that the formulated blend C was able to raise PCV and Hb above 50% and 17 g/dl (Normal control NC) respectively. Significant increase (P<0.05) in low density lipoprotein cholesterol (LDLc) was also observed in all the blends with blend C having the least (4.0 mg/dl) close to NC (2.0 mg/dl). Conclusion: From the results it is evident that blend C will manage and improve the health status of diabetic patients.

Diabetes is a chronic disease which characterized by hyperglycemia (elevated or abnormally high blood sugar levels) and other metabolic disturbances, including metabolism of lipids and haemostasis. Caesalpinia pulcherrima has previously showed strong anti-diabetic and hepatoprotective potential. The present research work was to investigate the anti-diabetic activity and hepatoprotective activity Caesalpinia pulcherrima in streptozotocin-induced (STZ) diabetic rats. The dose-dependent effects of 45days oral treatment with methanol extract of plant (200 and 300mg/kg) of CPAE on body weight, blood glucose level, total protein, albumin, liver marker enzymes and carbohydrate metabolizing enzymes were evaluated in STZ-induced diabetic rats. Oral administration methanolic extract of Caesalpinia pulcherrima of showed significant restoration of the body weight and decrease in the blood glucose level, liver marker enzymes (ALT, AST ALP) and carbohydrate metabolizing enzymes were observed in diabetic rats. These results suggest that fruit extract of Caesalpinia pulcherrima has valuable anti-diabetic activity in STZ-induced diabetic rats which is comparable to the standard drug metformin and hence might be of use in the management of diabetes.
