Abstract
A new sesquiterpene lactone glucoside, Ixerin Z1 (1), was isolated from the whole plants of Ixeris sonchifolia (Bge.) Hance, along with 15 known compounds. The structure of 1 was elucidated as 1(10),3,11(13)-guaiatriene-12,6-olide-2- one-3-O-[6′-(p-hydroxyphenylaceryl)]-gluco-pyranoside by spectroscopic methods including 2D-NMR techniques.
