Methyl dihydrojasmonate and its stereoisomers: sensory properties and enantioselective analysis.

Abstract

Enantiomeric methyl dihydrojasmonates (MDHJs) were separated by chiral gas chromatography (GC) and high performance liquid chromatography. Organoleptical evaluation clearly revealed that all four stereoisomers are odor-active and differ in their olfactory properties. Using enantio-multidimensional capillary GC–mass spectrometry with heptakis(2,3-di-O-methyl-6-O-tertbutyldimethylsilyl)-β-cyclodextrin as the chiral stationary phase, the direct enantioselective analysis of all four stereoisomers of MDHJ in numerous natural products was achieved for the first time.
