norbisabolane-type sesquiterpenoid, ashitabaol B and two bisabolane-type sesquiterpenoids, ashitabaols C and D, were isolated together with known sesquiterpenoids, ashitabaol A and (+)-bisabolangelone, from the seeds of Angelica keiskei (Miq.) Koidz. The structures including absolute configuration were determined on the basis of their spectroscopy, X-ray crystallography, and chemical conversions.
