Antihyperglycemic activity of total extract and fractions of Anogeissus leiocarpus
Abstract
Anogeissus leiocarpus (Combretaceae) is a medicinal plant used by traditional practitioners to treat people living with diabetes mellitus in Togo. The objective of this work was to evaluate the hypoglycemic activity of the plant. The hydroalcoholic extract and fractions of A. leiocarpus roots was evaluated on hyperglycemic mice by oral glucose tolerance test (OGTT) and on normoglycemic mice. The effect of the total extract and fractions was also measured on the adsorption and absorption of glucose respectively in vitro and ex vivo. At 30 minutes after glucose overload, the total extract and all fractions (supernatant and pellet) significantly (p< 0.0001) reduced hyperglycemia compared to controls. However, this reduction in hyperglycemia was greater in mice treated with the supernatant fraction at 100 mg.kg-1 during 180 minutes (p < 0.01). In our conditions, the extract at the 500 mg.kg-1 of the total extract in normoglycemic mice did not significantly decrease (p>0.05) basal blood glucose levels compared to controls. In vitro, the extract and fractions of A. leiocarpus adsorbed glucose and inhibited glucose intestinal absorption ex vivo. The results of this study support the use of A. leiocarpus as an antidiabetic plant.
