title: Allelopathic sesquiterpenoids from rhizomes of Petasites japonicus ssp. giganteus Kitam.
abstract: Four sesquiterpenoids were isolated from Petasites japonicus (Siebold and Zucc.) Maxim. ssp. giganteus (F. Schmidt ex Trautv.) Kitam. (Compositae, Japanese name: Akitabuki) as allelochemicals. Their structures were elucidated on the basis of spectroscopic methods and their allelopathic effects were assessed.
