This study was performed to determine the active constituents of the root of Panax ginseng C. A. Mayer in the amelioration of ethanol-induced impediment of brain growth in the neonatal stage. To establish an animal model of the brain growth impediment caused by ethanol, ethanol (6 g/kg s.c.) was administered to rat pups on postnatal day 6, which corresponded to the third trimester of pregnancy for humans. Brain weight, especially cerebellar weight, was significantly reduced in the ethanol-exposed pups. In contrast, neither separation from dams nor pentobarbital treatment affected brain weight. A saponin fraction of ginseng extract prevented this ethanol-induced reduction of brain weight. Some ginseng saponins including ginsenosides Rg1, Rb2, Rd, Rf and Re effected stimulated a potent recovery of cerebellum growth in this animal model.
