摘要: Abstract The 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 trixagol alkylated salicyclic acids. structures were elucidated by high field NMR techniques. Three South African gave no characteristic compounds.
