ABSTRACT
Objective:To evaluate the antidiabetic effect of galactomannans extracted from Adenanthera pavonina's L. seeds (GAP) in streptozotocin (STZ) induced diabetic mice.Methods:The preliminary galactomannan yield from Adenanthera pavonina L. plant and extraction products composition were evaluated. Various chemical characterization methods like thin layer chromatography, Fourier transform infrared spectroscopy,Results:The isolated and extracted galactomannan from Adenanthera pavonina was confirmed by various chemical characterization methods. GAP exhibited a 1.46:1 mannose: galactose ratio, and high molar weight. Both GAP enriched food decreased glycaemia, total cholesterol and triacylglycerol. GAP didn't interfere on food intakes or body weight, although it increased water intake. Furthermore, the relative liver weight indicated toxic galactomannan effects on the histopathological changes of the pancreas in STZ induced diabetes.Conclusions:It is concluded that GAP is a natural product that contains potent galactomannan and is useful in preventing and treating diabetes.
