 Abstract    The stereochemistry of the bisaboloids in chamomile—with the exception of bisabolol-oxide C—has been elucidated. The in-vitro-examination of the mutual convertibüities of some bisaboloids gave evidence for the stereochemical accordance of the common chiral centres of all the bisaboloids. The absolute configurations of the remaining third asym-metric carbon atoms in bisabololoxide A and B have been determined by NMR spectro-metric studies in comparison with their unnatural semisynthetic epimers. All the stereo-genie centres of the bisabololoxides A and B, of (—)-a-bisabolol and of bisabolonoxide A turn out to be S-configurated.
