Panax Ginsenosides are purified from Panax ginseng root by ethanol extraction, macroporous-resin chromatography and crystallisation.
This yields white to light-yellow powder with standardised ginsenoside content (50–98% total, or single-compound purity). Available as total ginsenosides, protopanaxadiols (Rb1, Rb2, Rc, Rd), protopanaxatriols (Rg1, Re, Rf) or rare ginsenosides (Rg3, Rh2, CK) for premium nutraceutical applications.
