We have examined the immunosuppressive effects of representative ginsenosides (Rb1, Rb2, Re and Rg1) from Panax ginseng C. A. Meyer on CD4+ and CD8+ lymphocyte proliferation. Ginsenosides differentially modulated lymphocyte proliferation induced by concanavalin A (Con A), lipopolysaccharide (LPS), phytohemaglutinin

Planta medica, 72(13), 1250-1253 (2006-09-19)
We investigated the apoptotic effects of the protopanaxadiol ginsenosides, Rb (1) and Rb (2), and their intestinal bacterial metabolite, 20-O-beta-D-glucopyranosyl-20(S)-protopanaxadiol (M1), and of the protopanaxatriol ginsenoside, Rg (1), and its intestinal bacterial metabolite, 20(S)-protopanaxatriol, in activated rat hepatic stellate cells

Acta pharmacologica Sinica, 24(2), 102-108 (2003-01-28)
The effect of ginsenoside Rb2 purified from Panax ginseng on fibrinolytic activity of bovine aortic endothelial cells (BAEC) was investigated. Cellular plasminogen activator (PA) level of the lysates was measured by the chromogenic substrate S-2403. Fibrin underlay technique was carried
