Various fractions of the alcoholic extract of the roots of Salacia mac
rosperma were evaluated for their antidiabetic activity in alloxan-dia
betic rats by estimating various biochemical parameters in blood, viz.
glucose, proteins, lipids, cholesterol, and free fatty acids, after o
ral administration for 8 days. From the data obtained, it is concluded
that the methanolic fraction followed by the residual fraction of the
alcoholic extract exhibited significant antidiabetic activity. These
biofractions were able to correct the metabolic abberations in diabeti
c rats. This activity may be due to their insulin-like properties.
