Ginsenosides are steroid-like substances; triterpene saponins. Ginseng contains more than 40 different ginsenosides. The main ginsenosides are Rg1, Rg2 and Rg3. It takes a lot of time and money to have ginsenosides analyzed. Most other ginsenosides in ginseng (in all types) are so minimal that it is difficult to identify them in an analysis.
