title: Oxygenated bisabolane fucosides from Carthamus lanatus L.
abstract: The aerial parts of Carthamus lanatus (Asteraceae) afforded four new oxygenated bisabolane fucosides, 10-hydroperoxy-bisabola-2,11-diene 7-O-beta-D-fucopyranoside, 11-hydro-peroxy-bisabola-2,9-diene 7-O-beta-D-fucopyranoside, 10-hydroxy-bisabola-2,11-diene 7-O-beta-D-fucopyranoside and 11-hydroxy-bisabola-2,9-diene 7-O-beta-D-fucopyranoside together with the known compounds a-bisabolol beta-D-fucopyranoside, asperuloside, sitosterol 3-O-beta-D-glucoside and stigmasterol 3-O-beta-D-glucoside. Asperuloside appears to be the second representative of the iridoid monoterpene group found in the plant family Asteraceae, which until recently was considered to lack iridoids. The main constituent a-bisabolol fucoside exhibited noticeable antibacterial and cytotoxic activities.
