دراسة فعالية مستخلصات أوراق و ثمار نبات Tribulus terrestris L. في تثبيط إنزيم α غلوكوزيداز

الملخص EN

Tribulus terrestris L.

leaves and fruits were extracted by means of ultrasonication using solvents of increasing polarity: hexane, acetone, ethanol, and water.

The in vitro anti-diabetic activity of different concentrations of these extracts was evaluated by studying their inhibition activity against α-glucosidase enzyme, in addition to study the inhibition mode for the most effective extract.

All extracts showed varying inhibition activity against α-glucosidase, The higher inhibition activity was observed in the non-polar or low polar extracts (hexane and acetone).

The hexane extract of fruits had the highest inhibition activity IC50=27.28μg/ml, and the inhibition mode was noncompetitive.
