Sulfonated guaianolides from Saussurea lappa.
Two new guaiane-type sesquiterpene lactones with an unusual sulfonic acid group, sulfocostunolide A (1) and sulfocostunolide B (2), were isolated from the roots of Saussurea lappa. Their structures were elucidated on the basis of extensive spectroscopic analysis.
