Pentacyclic triterpene alcohols, together with their acetate, myristate, and palmitate esters, comprise about 40% of the petroleum ether extract of the fruit (seed and pericarp) of two Jurinea species. All the triterpene esters and a porition of the free triterpene alcohols in the J. anatolica extract are derived from the pericarp portion of the fruit. The triterpene alcohol moieties and their approximate percentage of the hydrolyzed extract of J. anatolica fruit are α‐amyrin, 5%; β‐amyrin, 6%; lupeol, 6%; and ψ‐taraxasterol plus taraxasterol, 16%. J. consanguinea fruit extract yields essentially the same amount of the same five triterpene alcohols on hydrolysis. These concentrations of triterpenoid materials are believed to be the largest found in plant tissues.
