We have studied the effect of prior oral administration of an alcoholi
c extract of Picrorhiza kurroa, a traditional medicinal plant, on D-ga
lactosamine-induced hepatitis in rats with respect to mitochondrial fu
nction. Mitochondrial protein and the activities of TCA cycle enzymes,
respiratory marker enzymes, lipid peroxide and antiperoxidative enzym
es were determined in liver. Prior administration of Picrorhiza kurroa
extract significantly prevented the D-galactosamine-induced alteratio
ns in the level of protein and activities of TCA cycle enzymes and res
piratory marker enzymes in liver mitochondria. The extract also exerte
d an antioxidant effect against D-galactosamine hepatitis by blocking
the induction of lipid peroxidation and by increasing the activities o
f antiperoxidative enzymes to near normal. This preliminary study sugg
ests that Picrorhiza kurroa is hepatoprotective in rats. (C) 1998 Lipp
