Furanoeremophilanes in Senecio filaginoides and S. pinnatus.

Aerial parts of SENECIO FILAGINOIDES yielded two new furanoeremophilane type sesquiterpenoids: 6α-acetyloxy-10βH-furanoeremophil-1-one, 1 and 6α-tiglinoyloxy-10βH-furanoerernophil-1-one, 2. Their structures have been elucidated by spectroscopic data. From roots and aerial parts of S. PINNATUS 1α-hydroxy-6βangeloyloxy-10αH-furanoeremophil-9-one, 3 has been isolated.
