title: Structure elucidation and complete NMR spectral assignments of a novel sesquiterpene glycoside from Ixeris sonchifolia.
abstract: A novel sesquiterpene glycoside was isolated from the whole plant of Ixeris sonchifolia. The structure was established as 1(10)E-4Z-3alpha-hydroxy-germacra-1(10),4,11(13)-trien-6, 12-olide-14-O-beta-D-glucopyranoside (1) on the basis of spectroscopic techniques and chemical analysis.
