This study validates the antidiabetic efficacy of Enantia chlorantha stem bark and the possible therapeutic implications of the co-administration of lisinopril and E. chlorantha in type 2 diabetic rats. E. chlorantha stem bark was extracted by cold maceration. The inhibitory effect of the plant on carbohydrate metabolizing enzymes and its antioxidative potentials were assessed in vitro. The extract exhibited α-amylase and α-glucosidase inhibitory activities and also showed antioxidative properties in vitro. Administration of the extract normalized fasting hyperglycemia in vivo by showing 47.24% reduction in blood glucose levels relative to untreated diabetic rats. Co-administration of E. chlorantha and lisinopril restored serum glucose and serum lipid profile levels. E. chlorantha stem bark displayed antidiabetic potentials as compared with a standard antidiabetic drug (metformin). The study also showed that the plant contained some bioactive compounds which we hypothesize might be responsible for the observed activities. Co-administration of the plant with lisinopril conferred no significant therapeutic advantage on the serum glucose level and lipid profile.

Aims: The current investigation aimed to assess the antioxidant, antidiabetic and antilipidemic effects of the aqueous extract of aerial part of Cotula cinerea (C. cinerea). Background: Cotula cinerea (Del). which belongs to the Asteraceae family is commonly used traditionally for the treatment of diabetes. Objective: The objective of the study was to study the effect of the aqueous C. cinerea extract on glucose and lipid metabolism in normal and streptozotocin-induced diabetic rats using a single and repeated oral administration. Methods: A preliminary phytochemical screening and the quantification of phenolic and flavonoid contents as well as the antioxidant activity using three methods (DPPH, FRAP and ABTS) were carried out. The effect of a single and repeated (15 days of treatment) oral administration of the aqueous extract of aerial part of Cotula cinerea (AEAPCC) at a dose of 20 mg/kg on glucose and lipid profile was examined in normal and streptozotocin-induced diabetic rats. Additionally, histopathological examination of the pancreas and liver was carried out according to the Hematoxylin-Eosin method. Results: AEAPCC (20 mg/kg) showed a significant blood glucose-lowering activity in both normal and diabetic rats after a single and repeated oral administration during 15 days. The aqueous extract was also able to decrease the plasma triglycerides levels in both normal and diabetic rats after 15 days of oral treatment at a dose of 20 mg/Kg while no effect was observed on plasma cholesterol levels. In addition, the results show that AEAPCC exhibits an in vitro antioxidant activity using different tests. Histopathological analysis of the pancreas and liver of AEAPCC-treated diabetic rats has revealed that AEAPCC had a beneficial effect on the architecture of these organs while no improvement of glucose tolerance was noticed using the glucose tolerance test. Furthermore, the results showed that the extract is rich in several phytochemical compounds and exhibited an important antioxidant activity. The phytochemical screening revealed that AEAPCC contains polyphenolic compounds, flavonoids, tannins, alkaloids, saponins, quinones, sterols, terpenoids, anthroquinones and reducing sugars. Whereas, it is free from glycosides. Conclusion: In conclusion, this study demonstrates that Cotula cinerea possesses a beneficial effect on diabetes. Further investigations are required to study the mechanism of action of the antidiabetic effect of this plant.

Aim: This study aimed to evaluate the antidiabetic and antihyperlipidemic effects of Asteriscus graveolens. Background: Asteriscus graveolens (Asteraceae) is a medicinal plant widely used by the Moroccan population to treat various diseases including diabetes. Objective: This work aimed to assess the capacity of flavonoids extracted from Asteriscus graveolens (FEE) to improve diabetes mellitus and dyslipidemia in normal and STZ-induced diabetic rats. Methods: Flavonoids were extracted from A. graveolens using the Soxhlet apparatus and using different organic solvents. Normal and streptozotocin-induced diabetic rats were treated orally by the extract of A. graveolens at a dose of 10 mg/kg. The oral treatment during 15 days was used to evaluate the effect of the flavonoids extracted from A. graveolens on blood glucose level and lipid profile in normal and diabetic rats. The oral glucose tolerance test as well as the analysis of histopathological examination of liver was performed. The antioxidant activity of FEE was also assessed by the method of trapping of free radical 2,2-diphenyl-1 picrylhydrazyl (DPPH), in order to estimate the mechanisms of action involved by FEE to improve hyperglycemia and lipid profile in normal and diabetic rats. Results: FEE reduced serum glucose concentrations in both normal and diabetic rats and exhibited in the last group lowering total cholesterol and triglycerides effects as well as improvement of the HDL-cholesterol serum level. In addition, a remarkable influence on glucose tolerance was also noticed after FEE treatment. Moreover, FEE was able to improve histopathological status of liver and possess a potential antioxidant effect in vitro. Conclusion: In conclusion, this study demonstrates the hypoglycemic and antihyperlipidemic effects of FEE in rats supporting then its traditional use for the management of diabetes.

Aims: Arganimide A (4,4-dihydroxy-3,3-imino-di-benzoic acid) is a compound belonging to a family of aminophenolics found in fruit of Argania spinosa. The purpose of this study was to investigate the glucose and lipid lowering activity of Arganimide A (ARG A). Methods: The effect of a single dose and daily oral administration of Arganimide A (ARG A) on blood glucose levels and plasma lipid profile was tested in normal and streptozotocin (STZ) diabetic rats at a dose of 2 mg/kg body weight. Results: Single oral administration of ARG A reduced blood glucose levels from 26.50±0.61 mmol/L to 14.27±0.73 mmol/L (p<0.0001) six hours after administration in STZ diabetic rats. Furthermore, blood glucose levels were decreased from 5.35±0.30 mmol/L to 3.57±0.17 mmol/L (p<0.0001) and from 26.50±0.61 mmol/L to 3.67±0.29 mmol/L (p<0.0001) in normal and STZ diabetic rats, respectively, after seven days of treatment. Moreover, no significant changes in body weight in normal and STZ rats were shown. According to the lipid profile, the plasma triglycerides levels were decreased significantly in diabetic rats after seven days of ARG treatment (p<0.05). Moreover, seven days of ARG A treatment decreased significantly the plasma cholesterol concentrations (p<0.001). Conclusion: ARG A possesses glucose and lipid-lowering activity in diabetic rats and this natural compound may be beneficial in the treatment of diabetes.
