| Abstract: | From the aerial part of Centaurea canariensis three sesquiterpene lactones were isolated: cynaropicrin, deacylcynaropicrin and aguerin A. The same species, grown from seed, yielded cynaropicrin, deacylcynaropicrin and aguerin B. The guaianolides aguerin A and B are reported for the first time. Aguerin B was subsequently found to be present in Centaureana linifolia, C. canariensis (var subspinnata) and C. sventenii. |
