eng Essential Oil Composition of Garcinia nigrolineata Planch. ex T. Anderson (Clusiaceae)
Salleh, Wan Mohd Nuzul Hakimi Wan; Khamis, Shamsul
The present study aims to examine the chemical composition of the essential oils of the leaves of Garcinia nigrolineata. The essential oil was extracted by hydrodistillation and characterized by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). In total, 37 chemical components were identified in the essential oil which made up 98.3 % of the total oil composition. The essential oil is composed mainly of β-caryophyllene (25.2 %), α-humulene (12.8 %), valencene (6.2 %), α-cadinol (5.8 %), and germacrene...

eng Free and Glycosidically Bound Volatiles of <i>Mentha citrata</i> Ehrh.
Mastelić, Josip; Miloš, Mladen; Kuštrak, Danica
Croatica Chemica Acta Vol. 73, No. 3, 2000
Free and glycosidically bound volatiles of surficial parts of <i>Mentha citrata</i> were investigated. Free volatile compounds were isolated from dried plant material by two methods: hydrodistillation and extraction with pentane used as control. Free volatile compounds as well as the aglycones obtained after enzymatic hydrolysis of gly-cosides were analyzed by gas chromatography-mass spectrometry (GC-MS). A significant difference in qualitative and quantitative composition of volatile compounds of the essential oil and pentane extract was found...

hrv Utjecaj tehnike ekstrakcije na sastav hlapljivih sastojaka oleoresina iz drva Pinus brutia Ten.
eng Effect of Extraction Technique on Composition of Volatile Constituents of Oleoresin from Pinus Brutia Ten.
Yasar, Samim; Beram, Abdullah; Guler, Gurcan
Drvna industrija Vol. 69, No. 3, 2018
Za ovu su studiju hlapljivi sastojci oleoresina iz drva Pinus brutia Ten. izdvojeni mikroekstrakcijom čvrste faze (SPME) i hidrodestilacijom. Radi određivanja hlapljivih sastojaka terpentinskog ulja (dobivenoga hidrodestilacijom) i ekstrakta oleoresina (dobivenoga SPME-om), provedena je plinska kromatografija i masena spektrometrija (GC/MS). Jedanaest hlapljivih spojeva sadržavalo je terpentinsko ulje dobiveno hidrodestilacijom, dok je ekstrakt dobiven SPME-om sadržavao 32 hlapljiva spoja. Tri karakteristična hlapljiva sastojka u terpentinskom...

eng Volatile Organic Compounds of Marine Sponge Petrosia ficiformis from the Adriatic Sea
Radman, Sanja; Maras, Elena; Jerković, Igor
Croatica Chemica Acta Vol. 94, No. 4, 2021
Volatile organic compounds (VOCs) of Petrosia ficiformis were investigated for the first time. The VOCs from fresh and air-dried sponge were obtained by hydrodistillation and headspace-solid phase microextraction and they were analysed by coupled gas chromatography-mass spectrometry. Aliphatic compounds with octan-3-one (up to 24.02 %), oct-1-en-3-ol (up to 8.65 %) and heptadecane (up to 39.37 %) were the most abundant in the fresh sponge along with benzaldehyde (up to 18.59 %) and diisobutyl phthalate (up to 8.44 %). Higher percentage of N,N...

hrv BioProspecting Jadranskog mora: Pregled dosadašnjih istraživanja isparljivih organskih spojeva
eng BioProspecting of the Adriatic Sea: A Review of Recent Studies of Volatile Organic Compounds
Kranjac, Marina; Zekić, Marina; Radonić, Ani; Marijanović, Zvonimir; Jokić, Stela; Jerković, Igor
Kemija u industriji Vol. 69, No. 9-10 (special issue), 2020
Istraživanja predstavljena u ovom preglednom radu doprinose poznavanju isparljivih organskih spojeva iz morskih organizama, posebno iz makroalgi Jadranskog mora. Za izolaciju isparljivih spojeva iz svježih i/ili na zraku osušenih uzoraka primijenjene su komplementarne metode: mikroekstrakcija vršnih para na čvrstoj fazi (HS-SPME) i/ili hidrodestilacija (HD). Dobiveni izolati analizirani su vezanim sustavom plinske kromatografije-spektrometrije masa (GC-MS). U vršnim parama i isparljivim uljima makroalgi <i>Halopteris filicina</i>, <i>Flabellia...
