Popis:	A chemical study on tissue cultures from leaves and flowers of E. camaldulensisDehnh. afforded the new natural product (2α,3β)-2,3,23-trihydroxy-13,28-epoxyurs-11-en-28-one (dryobalanolide) together with the known pentacyclic triterpenoids: betulinic acid, oleanolic acid, ursolic acid, (2α,3β)-2,3,23-trihydroxyolean-12-en-28-oic acid (arjunolic acid), (2α,3β)-2,3,23-trihydroxyurs-12-en-28-oic acid (asiatic acid), (2α)-2-hydroxyursolic acid, (2α)-2-hydroxyoleanolic acid (maslinic acid), as well as β-sitosterol. The extracts and the isolated compounds were evaluated against eleven human pathogenic microorganisms, exhibiting a very interesting antibacterial spectrum of activities.
