The effect of abrus precatorius methanol leaves extract in inhibiting glucose absorption in in vitro study
Abrus precatorius leaves have been used traditionally for treatment of Type II diabetes in Malaysia. In this study, the potential of the 80% methanolic extract of Abrus precatorius leaves has been studied for its a-glucosidase inhibitory activity and its glucose diffusion effect. The extract of this...
