| Abstract: | Aqueous extract of the wood ofPterocarpus marsupium, commonly known as ‘bijasar’, is used in Indian Ayurveda system of medicine for treatment of diabetes. The active anti-diabetic
principle in its aqueous extract has been found to be (-)epicatechin, a flavonoid. The present work was undertaken to study
the effect of (-)epicatechin on erythrocyte membrane Ca++-ATPase from type 2 diabetic patients. The activity of erythrocyte Ca++-ATPase was significantly lower in type 2 diabetics.In vitro insulin treatment of erythrocyte ghosts, resulted in the increase of Ca++-ATPase activity in diabetic patients. Treatment with (-)epicatechin (1mM) resulted in an increase in the activity of erythrocyte
Ca++-ATPase in both normal individuals and type 2 diabetic patients. The insulin like effect of (-)epicatechin on erythrocyte
membrane Ca++-ATPase in type 2 diabetics is an interesting finding. Further work is needed to elucidate the mechanism of action of (-)epicatechin
on modulation of erythrocyte membrane bound enzymes. |
