10 th <str<strong>on</strong>g>Symposium</str<strong>on</strong>g> <strong>on</strong> <strong>the</strong> <strong>Flora</strong> <strong>of</strong> Sou<strong>the</strong>astern <strong>Serbia</strong> <strong>and</strong> Neighbouring regi<strong>on</strong>s,Vlasina 17 to 20 June 2010plant development, this work indicates that chemical polymorphism <strong>of</strong> endemic S.menthifolia does not manifest in <strong>the</strong> regi<strong>on</strong> <strong>of</strong> Croatian Mediterranean area.Volatile C<strong>on</strong>stituents <strong>of</strong> Satureja cuneifolia Ten. fromBiokovo MountainAnela Kulenović, Sanja Ćavar, Danijela Vidic, Marija Edita Šolić, MilkaMaksimovićDepartment <strong>of</strong> Chemistry, Faculty <strong>of</strong> Science, University <strong>of</strong> Sarajevoanelak1986@live.comSatureja cuneifolia Ten. is well known aromatic plant growing wild inMediterranean area. Volatile pr<strong>of</strong>ile <strong>of</strong> odorous parts <strong>of</strong> S. cuneifolia, collected from<strong>the</strong> natural habitat at Biokovo Mountain, was analyzed by capillary GC-MSanalysis. The identificati<strong>on</strong> <strong>of</strong> <strong>the</strong> volatiles was accomplished by computer librarysearch, retenti<strong>on</strong> indices RI, <strong>and</strong> <strong>the</strong> visual comparis<strong>on</strong> <strong>of</strong> mass spectra with thosefound in <strong>the</strong> literature <strong>and</strong> in <strong>the</strong> laboratory own database. This work presents <strong>the</strong>comparis<strong>on</strong> <strong>on</strong> volatile chemical compositi<strong>on</strong> <strong>of</strong> S. cuneifolia obtained byhydrodistillati<strong>on</strong> <strong>and</strong> headspace technique. Exactly seventy comp<strong>on</strong>ents wereidentified in both samples, representing 82.4% <strong>and</strong> 97.7% in total, for hydrodistilledoil <strong>and</strong> headspace, respectively. The most abundant compounds in essential oil werecarvacrol (16.8%), <strong>and</strong> oxygenated sesquiterpenes spathulenol (12.7%),caryophyllene oxide (9.0%), amorpha-4,9-dien-2-ol (6.4%), <strong>and</strong> alpha-cadinol(4.5%). In c<strong>on</strong>trast to essential oil compositi<strong>on</strong>, <strong>the</strong> main c<strong>on</strong>stituents <strong>of</strong> headspacesample were p-cymene (22.6%), linalool (20.1%), lim<strong>on</strong>ene (9.3%), <strong>and</strong> carvacrolmethyl e<strong>the</strong>r (5.2%) that all were not find in hydrodistilled oil. Presented resultssignificantly differ from data published earlier. Essential oil <strong>of</strong> <strong>the</strong> same speciesfrom Croatia showed variati<strong>on</strong>s in quantitative <strong>and</strong> qualitative chemicalcompositi<strong>on</strong>, depending <strong>on</strong> <strong>the</strong> locality <strong>and</strong> envir<strong>on</strong>mental c<strong>on</strong>diti<strong>on</strong>s. However,essential oil <strong>of</strong> S. cuneifolia from Turkey had similarity in qualitative, but not inquantitative chemical compositi<strong>on</strong> with our results. These findings are in agreementwith <strong>the</strong> fact <strong>of</strong> complex chemical polymorphism <strong>of</strong> Satureja genus.90
