Abstract
(SG) attenuate alcohol or endotoxin-induced acute liver injury in mice. Whole SG contains eight times more ginsenosides than the root and, because it grows quickly ([Formula: see text]30 days) without using pesticides, the whole-plant can be harvested. The extracts were enriched in phenolics and flavonoids and showed high radical scavenging activities. Mice received oral administration of SG or fermented SG (FSG) extracts 1 h before an injection of either ethanol or lipopolysaccharide and D-galactosamine (LPS/GalN). The latency of righting reflex was monitored to examine the effect of extracts on relieving hangover symptoms. The results indicate that FSG significantly reduced the latency of righting reflex, SG and FSG increased the activity and expression of ethanol-metabolizing enzymes, and FSG decreased hepatic necrosis and plasma levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). During the ethanol metabolism, cytochrome P450 2E1 expression was increased, but 4-hydroxynonenal levels were decreased by the extracts due to their anti-oxidant activity. LPS/GalN-induced liver injury was reduced by SG and FSG; plasma ALT and AST levels, hepatic necrosis, and apoptotic and inflammatory markers were all decreased. In conclusion, SG extracts attenuated ethanol-induced hangover and endotoxin-induced acute liver injury, and fermentation enhanced the efficacy with regard to relieving hangover.
