• Sesquiterpenoid

Phytochemical investigation of the whole plants of Petasites japonicus and Petasites tricholobus led to the isolation of five new bakkenolide-type sesquiterpenoids, bakkenolide-Ib (1), bakkenolide-IIb (2), bakkenolide-IIIb (3), bakkenolide-IVb (4), and bakkenolide-Vb (5), and a new eremophilane-type norsesquiterpenoid, petasindiol (6). Their structures were elucidated by NMR and HRESIMS analyses. Petasindiol (6) represented the first example of 15-noreremophilane sesquiterpenoid from the genus Petasites.
