The aqueous extract was prepared from B. senegalensis seed powders under the extraction conditions: time (10 min), temperature (55˚C) and the ratio of mass of flour/volume of water (3/10 g/mL). Male wistar rats aged 6 to 8 weeks were acclimated and divided into 8 groups of 5 rats each: two normal control groups which received a normal standard diet (3810 kcal/kg), and six test groups which were subjected to a hyperlipidemic diet (5310 Kcal/kg). All groups of animals were fed in this manner for 8 weeks to induce hyperglycemia, hyperlipidemia and oxidative stress. After induction the animals were treated either with distilled water for the normal and negative control groups or with atorvastatin for the positive control group or with the extract of B. senegalensis. (125, 250 and 500 mg/kg) for the test groups. Fasting blood glucose was taken every 7 days during induction. After sacrifice, biochemical and oxidative stress parameters were measured. The aqueous extract of B. senegalensis significantly decreased (p B. senegalensis at a dose of 500 mg/kg has the capacity to reduce blood sugar, improve the quality of the lipid profile and reduce oxidative stress. Thus, the results reveal that the aqueous extract of B. senegalensis has powerful hypoglycemic, hypolipidemic and antioxidant properties.展开更多

Obesity has long been considered a simple aesthetic problem linked to excessive gluttony. It is however recognized today as a real pathology, so much so that the WHO has declared it as “the first non-infectious epidemic in history and a major problem of the century”. In addition, many studies have been carried out aimed at the production of less fatty foods and, scientifically, at the development of anti-obesity drugs. Thus, the objective of this study is to evaluate the anti-obesity effect of the extract of Boscia senegalensis (Capparaceae) used in Chad to fight against type II diabetes and metabolic syndrome. Methodology: A bromatological study of Boscia senegalensis extract was carried out at the Food Quality Control Centre (CECOQDA) in Ndjamena (Chad), followed by an in vivo study of rabbits carried out at the IRED Biotechnopôle laboratory (Chad). Results: The results obtained from the 100 g bromatological study of the dry extract of Boscia senegalensis are as follows: protein content (20.24% ± 0.007%), fat content (5.92% ± 0.21%), carbohydrate content (35.16% ± 1.05%), fibre content (2.11% ± 0.26%), moisture content (5.7% ± 0.14%) and ash content (2.90% ± 0.03%). No aflatoxin was detected in the dry extract of Boscia senegalensis. A significant decrease (p = 0.04) in body weight was observed in rabbits treated with Boscia senegalensis extract compared to controls. In addition, histological sections of the various organs (liver, spleen, kidneys) of treated rabbits showed no lesions following the incorporation of the extract of Boscia senegalensis. Conclusion: This study showed the anti-obesity effect of Boscia senegalensis. It also made it possible to verify the harmlessness of the product with regard to the results on chronic toxicity.展开更多
