Chiral GC analysis of (S)(+)‐ and (R)(−)‐carvone with high enantiomeric purity in caraway, dill and spearmint oils

Abstract (S)(+)‐Carvone with high enantiomeric purity was detected in the seed and herb oils of caraway and dill. High enantiometic purity of (R)(‐)‐carvone was detected in the oils of spearmint from various sources. Direct enantiomer separation of carvone from essential oils and synthetic samples was performed using Lipodex E as a chiral y‐ cyclodextrin stationary phase.
