Abstract:The present investigation has shown that Ginseng rcot saponins(ig , 50mg/kg×7d) facilitate the learn-ing and memory of normal male Wistar rats ,while the effect of Ginseng stemleaf saponinstig , 50mg/kg×7d ) on anti-electroconvulsive shock-induced impairment of memory consolidation in rats is more intensive than that of rootsaponins. Both Ginseng root and stem-leaf saponins can signifcantly raise the levels of biogenic monoamines in normalrat’s brain.
