ginsenoside

Ginsenosides are a class of steroid-like compounds, triterpene saponins, found exclusively in Panax. Ginsenosides have been the target of research, as they are viewed as the active compounds behind the claims of ginseng's efficacy. Since ginsenosides appear to affect multiple pathways, its effects are complex and difficult to isolate.

Ginsenosides

Ginsenosides are identified by column chromatography. Ginsenoside content can vary widely depending on species, location of growth, and growing time before harvest.

Rb1

Appears to be most abundant in Panax quinquefolius. Rb1 seems to affect the reproductive system in animal tests. Recent study shows that Rb1 affects rat embryo development http://www.eshre.com/ecm/main.asp?lan=99&typ=308. Another study shows that Rb1 may increase testosterone production in male rats indirectly through the stimulation of the luteinizing hormone.
