Enhancement of nitric oxide production from activated macrophages by a purified form of ginsenoside (Rg1).


We studied the actions of purified ginsenosides Rg1 and Rb1 on nitric oxide production from macrophages and a macrophage cell line RAW264-7. Although neither Rg1 nor Rb1 induced nitric oxide from resting macrophages, Rg1 enhanced the production of nitric oxide from IFN-gamma activated-macrophages or RAW cells. Rg1 also enhanced the production of nitric… (More)
