Abstract
AbstractSeveral monoterpenes, i.e., (+)-α-pinene, (−)-camphene, sabinene, (−)-β-pinene, myrcene, R-(+)-limonene, (−)-bornylacetate, (−)-trans-caryophyllene and a-humulene were identified and determined by gas chromatography-mass spectrometry (GC-MS) in needles of Pinaceae (Picea abies, P. omorika, P. pungens, P. Breweriana, Pinus nigra, P. mungo turra, P. black, P. sylvestris, Abies pinsapo, A. holophylla, A. Bronmuelleris, A. alba, Larix Kaempferi L. decidua) and tree-leaves of Juglandaceae (Juglans regia, J. nigra, J. sieboldiana var. Cordiformis) families. Supercritical fluid extraction (SFE) was found to be very useful for their isolation at optimised conditions (needles/leaves: pressure 20/30 MPa, temperature 80/130°C, time of extraction 60/60 min, modifier chloroform/chloroform). Their seasonal distribution, evaluation of differences in concentrations and relative amounts in different trees and their varieties grown in different localities were evaluated.
