investigation of 17 Australian Helipterum species afforded 32 new sesquiterpene lactones (four germacranolides, 22 guaianolides and six eudesmanolides), a bisabolene derivative, four ent -beyerene derivatives, cembrol, an isomer of trixagol and four alkylated salicyclic acids. The structures were elucidated by high field NMR techniques. Three South African species gave no characteristic compounds.
