Abstract Further investigation of the minor terpenoids in Helianthusniveus subsp. canescens and H. argophyllus afforded two known 12,8-fused sesquiterpenelactones, 3-acetylchamissonin and simsiolide as well as one new germacranolide, argophyllin C. Identification and structure elucidation of these lactones by 1 H NMR and chemical transformations are described.
