Background: Corrigiola telephiifolia Pourr, is a perennial species, woody distributed throughout the north of Africa. This plant is used in traditional Mediterranean preparations and has many traditional uses especially treatment of diabetes. Aim/Methods: The current research was carried out to evaluate the antidiabetic effect of Aerial Parts of Aqueous Extract (APAE) of Corrigiola telephiifolia (C. telephiifolia) on both normal and streptozotocin (STZ)-induced diabetic rats treated at a dose of 5 mg/kg for fifteen days. Additionally, the histopathological changes in the liver, morphometric analysis, Oral Glucose Tolerance Test (OGTT) in normal rats and preliminary phytochemical screening for various components were realized. Results: Single oral administration of the APAE of C. telephiifolia (5mg/kg) showed no significant change in glycaemia of normal and STZ-induced diabetic rats. In contrast, repeated oral administration of C. telephiifolia reduced blood glucose levels from 4.11 ± 0.10 mmol/L to 3.16 ± 0.16 mmol/L (p<0.01) 15 days after administration in normal rats. Furthermore, blood glucose levels decreased from 17.84 ± 1.75mmol/L to 1.93 ± 0.33 mmol/L (p<0.0001) in STZ diabetic rats after fifteen days of treatment. According to the oral glucose tolerance test, C. telephiifolia (5 mg/kg) was shown to prevent significantly the increase in blood glucose levels in normal treated rats 30 min after glucose administration when compared to the control group. Also, the liver architecture of diabetic rats treated by C. telephiifolia was improved when compared with the liver architecture of untreated diabetic rats. Concerning the preliminary phytochemical screening of C. telephiifolia, several compounds have been found such as polyphenols, flavonoids, saponins, mucilage and terpenoids. Conclusion: The results show that the aqueous extract of C. telephiifolia possesses significant antihyperglycemic activity.

Context. Nigella sativa seeds are usually used as traditional medicine for a wide range of therapeutic purposes. Objective. To investigate the subacute toxicity of NS aqueous extract and select its lowest dose to study its antidiabetic effect. Methods. 5 AqE.NS doses (2, 6.4, 21, 33, and 60 g/Kg) were daily administered to mice by gavage. Biochemical parameters measurements and histological study of the liver and the kidney were performed after 6 weeks of supplementation. Thereafter, and after inducing diabetes by alloxan, rats were treated by 2 g/Kg of AqE.NS during 8 weeks. Metabolic parameters were measured on sera. A horizontal electrophoresis of plasmatic lipoprotein was conducted. Glycogen, total lipids, and triglycerides were measured in the liver. TBARS were evaluated on adipose tissue, liver, and pancreas. Results. AqE.NS showed no variation in urea and albumin at the 5 doses, but hepatotoxicity from 21 g/Kg was confirmed by histopathological observations of the liver. In diabetic rats, AqE.NS significantly decreased glycemia, TG, T-cholesterol, LDL-c, and TBARS and showed a restored insulinemia and a significant increase in HDL-c. Results on the liver indicated a decrease in lipids and a possible glycogenogenesis. Conclusion. AqE.NS showed its safety at low doses and its evident antihyperglycemic, antihyperlipidemic, and antioxidant effect.
