Abstract:

The enantiomeric differentiation of borneol isolated from laboratory-produced and commercial essential oils was determined using a fused-silica Cyclodex-B capillary column. High enantiomeric purities of (-)-borneol were detected in the oils of Coridothymus capitatus, Artemisia herba alba, Origanum vulgare, Ocimum canum and feverfew. High enantiomeric purities of (+)-borneol were detected in lavandin essence and in lavandin oil. The different enantiomeric distributions of (+)-borneol in lavender and in lavandin may aid in distinguishing between the two oils or essences. The wide variation of borneol enantiomers among rosemary oil cultivars indicates genetic variability in the genus Rosmarinus. There is no characteristic distribution of the enantiomers of borneol and its biosynthetic oxidation product, camphor, in Salvia officinalis oils.The enantiomeric differentiation of borneol isolated from laboratory-produced and commercial essential oils was determined using a fused-silica Cyclodex-B capillary column.
