Abstract
Ginsenosides Rb.sub.1 and Rg.sub.1 enhance the avaiability of acetylcholine in the cortical and hippocampal regions of the brain and alleviate the symptoms of Alzheimer-type senile dementia. Pure Rb.sub.1 is isolated from a mixture of ginsenosides by a process involving vacuum chromatography on silica gel. Preferably, the mixture of ginsenosides is enriched in Rb.sub.1 by partition between an aqueous system and water ethyl acetatebutanol.
