متن کاملStereoisomers of Saponins in Panax notoginseng (Sanqi): A Review
Panax notoginseng (Sanqi), a traditional Chinese medical drug which has been applied to medical use for over four centuries, contains high content of dammarane-type tetracyclic triterpenoid saponins. A number of stereoisomeric dammarane-type saponins exist in this precious herb, and some are particularly regarded as "biomarkers" in processed notoginseng. Contemporary researches have indicated t...
