Abstract
From the overground parts of Gnaphalium obtusifolium (Compositae) there was isolated a flavanone substituted by a biogenetically unusual C9-unit (= obtusifolin). Mass-, UV-, IR-, PMR-spectra are correlated on the basis of a structure previously established by X-ray analysis CHOPPE et al. 12).
