From the methanolic extract of the aerial parts of Petasites japonicus, six new eremophilane-type sesquiterpenoids, petasitesterpenes I-VI were isolated together with eight known compounds including S-japonin and eremophilenolide. The chemical structures of the isolated new compounds were elucidated
