Secondary metabolites from the aerial parts of Centaurea pannonica
Further investigation of Centaurea pannonica (Heuffel) Simonkai [collected in Šumadija region-Serbia, on September 2008], afforded the new sesquiterpene lactone (1), compound 2, previously described, as well as eleven known guaianolides, namely, babylin A, babylin B, chlorohyssopifolin C, repin, repdiolide, epoxy-repdiolide, chlororepdiolide, cebellin J, janerin, 19-deoxyjanerin, rhaposerine, three known lignans arctigenin, matairesinol, arctiin, three known flavonoids, apigenin, hispidulin, diosmetin and one known phenyl propanoid glucoside, syringine. The presence of guaianolides is characteristic feature of Centaurea taxa belonging to the section Jacea, where is classified C. pannonica [2, 3].
