Separation of terpinen-4-ol enantiomers performed by a chiral GC columnand a chiral lanthanide shift reagent Eu(hfc)3, showed that the enantiomeric composition of an isolated compound from sweet marjoram oil was 73% (5)(- -) 27% R) —). The (4f )(—)-enantiomer was found in the oil of Eucalyptus dives Terpinen-4-ol was also found in several bark beetle species and is the main component in the aggregation pheromone of Polygraphuspoligraphus ...
