Investigation of lipophilic exudates from the aerial parts of Balsamorhiza sagittata and B. macrophylla afforded three new highly oxygenated guaianolides (1—3), in addition to known guaianolides, germacranolide and eudesmane acids. Their chemical structures were elucidated by spectroscopic methods and the data for the compounds are reported in Tables 1 and 2 and in Experimental.
