Pseudoginsenoside F11

Pseudoginsenoside F11 is a chemical natural product found in American ginseng (Panax quinquefolius) but not in Asian ginseng (Panax ginseng), although it has similar properties to the Asian ginseng compound ginsenoside Rf.[1] The molecule is a triterpenoid saponin member of the dammarane family and contains a four-ring rigid skeleton.[1] Compounds in the ginsenoside family are found almost exclusively in plants of the genus Panax. A wide variety of difficult-to-characterize in vitro effects have been reported for the compounds in isolation.[2][3] Pseudoginsenoside F11 and its derivatives are sometimes referred to as having an ocotillol-type skeleton structure.[1][4]

Studies in mice have identified antagonistic effects on the actions of other well-characterized drugs, such as scopolamine,[5] morphine,[6][7] and methamphetamine.[8]
