Sesquiterpene lactones and other constituents from Hymenoxys richardsonii and H. subintegra.
Two Hymenoxys species afforded, in addition to known compounds, three new pseudoguaianoloides, a new sesquiterpene glucoside and a new butyrolactone. This is the first report of an eudesmane from the genus Hymenoxys. The structures were elucidated by high-field NMR and chemical transformations.
