The antidepressant effects of ginsenoside Rb3 and Rg3, Rh2, C-K, and PPD were compared.
C-K showed similar activities to Rb3, whereas Rg3 had better effects than Rb3.
Rg3, C-K and Rb3 increased the NA levels in the brain regions of mice.
Rg3 reversed stress-induced increase in the levels of serum ACTH and corticosterone.
