title: Two new sesquiterpene lactones from Ixeris sonchifolia.
abstract: The structures of two new sesquiterpene lactones, 11,13beta-dihydroixerin Z (1) and Ixerin Z2 (2) isolated from Ixeris sonchifolia were determined to be 3-hydroxy-1(10),3-guaiadiene-12,6-olide-2-one-3-O-beta-D-glucopyranoside and 1(10),3,11 (13)-guaiatriene-12,6-olide-2-one-3-O-[6'-(4"-hydroxybenzyl lactyl)]-beta-D-glucopyranoside, respectively on the basis of detailed spectral analysis.
