title: Enantiomeric and non-enantiomeric monoterpenes of Juniperus communis L. and Juniperus oxycedrus needles and berries determined by HS-SPME and enantioselective GC/MS.
abstract: For the first time, enantiomeric and non-enantiomeric distribution of monoterpenes in the headspace of Juniperus communis L. and Juniperus oxycedrus needles and berries has been determined using HS-SPME combined with enantioselective GC/MS. The essential oils from needles and berries of both Juniperus species obtained by hydrodistillation were also performed. HS-SPME has shown good potential to reproduce the same results as the commonly used hydrodistillation extraction technique. While needles and berries of J. communis showed high contents of sabinene, α-pinene and β-myrcene with 19-30%, 12-24% and 9-20%, respectively, J. oxycedrus was strongly dominated by α-pinene with 85-92% in both needles and berries. Large variations in chiral distribution of monoterpenes within the same plant species and between the two junipers were observed. Interestingly, similar enantiomeric preferences of monoterpenes were obtained between needles and berries of the two junipers.
