GC-MS analysis of essential oils of some Juniperus taxa

In this study, naturally occurring species in Kastamonu The efficiency of the essential oils obtained by hydro distillation of the conifers and fruits of species J. oxycedrus L., J. excelsa Bieb., J. communis L. var. nana Syme., J. sabina L. and the chemical substance contents, including their hydrosols, were determined by GC-MS analysis. Leaf and fruit samples were collected from four regions where they grow wild within the borders of Kastamonu. Productivity rates of essential oils in fruit and leaf materials are approximately (f/l), 0,85 / 0,40% in J. oxycedrus, 1,20 / 0,90% in J. excelsa Bieb., 1,95 / 1,50% in J. communis var. nana and 1,93 / 2,30% in J. sabina. It was determined as. According to the results of GC-MS analysis, 4 juniperus spp. The main volatile components above 2% in the fruit (f), fruit hydrosol (f h), leaf (l) and leaf hydrosol (l h) contents of the species were listed.
