摘要:

AbstractThe simultaneous stereodifferentiation of all aromarelevant 4(5) alkylsubstituted γ(δ)‐lactones is described, using enantioselective multidimensional gas chromatography (MDG), and the column combination OV 1701/octakis(3‐O‐butyryl‐2,6‐di‐O‐pentyl)‐γ‐cyclodextrin. The method is applicated to the lactone flavour compounds of fruits, indicating the advance to the analytical differentiation between “natural” and “nature‐identical” aromas. Modified cyclodextrins are also proved to be powerful tools in the chirospecific CGC analysis of monoterpenoid constituents of essential oils. Optical purity control is discussed as an indi
