Chemical Taxonomy

Description

belongs to the class of organic compounds known as triterpene saponins. These are glycosylated derivatives of triterpene sapogenins. The sapogenin moiety backbone is usually based on the oleanane, ursane, taraxastane, bauerane, lanostane, lupeol, lupane, dammarane, cycloartane, friedelane, hopane, 9b,19-cyclo-lanostane, cycloartane, or cycloartanol skeleton.
