Two new sesquiterpene glucosides from Ixeris plants



Two new sesquiterpene glucosides from Ixeris plants



Advances in plant glycosides, chemistry and biology Proceedings of the international symposium on plant glycosides, Kunming, China, 12-15 August, 1997: 394-398



The whole plants of I. denticulata f. pinnatipartita and I. sonchifolia, respectively, afforded a new guaianolide sesquiterpene lactone glucoside named ixerin X, 8,15-dihydroxy-1(10),3,11(13)-guaiatriene-12,6-olide-15-O- beta -D-glucopyranoside, and ixerin Z, 1(10),3,11(13)-guaiatriene-12,6-olide-2-one-3-O- beta -D-glucopyranoside, whose structure and stereochemistry were determined by spectroscopic methods.
