We have been investigating the constituents of the buds of about 120 strains of P. japonicus, which were growing mainly in the central part of Japan, and found many types of chemovars. These chemovars contained eremophylane and its related sesquiterpenoids such as fukinone, fukinanolide (bakkenolide A), fukinolide (bakkenolide B) and isopetasin, which are main principles of the characteristic odor and bitter taste of the bud of P. japonicus Maxim. Of these strains, we found three typical chemovars, and the main components of which were fukinone, fukinolide (bakkenolide B) and isopetasin respectively. This is the first report about the chemovars of P. japonicus Maxim, and this result is very interesting from the view point of the biogenetical and chemotaxonomical studies.
