    Eski?ehir Osmangazi Üniversitesi Müh.Mim.Fak.Dergisi C. XVIII, S.2, 2005 Eng.&Arch.Fac. Eski?ehir Osmangazi University, Vol. XVIII, No: 2, 2005 RECOVERY OF FIXED AND VOLATILE OILS FROM LAURUS NOBILIS L.FRUIT AND LEAVES BY SOLVENT EXTRACTION METHOD Macid NURBA? [NOURBAKHSH] 1 , Yeliz BAL 2 ABSTRACT : In this study, fixed oils of Laurus nobilis L. fruit were obtained by solvent extraction (Soxhlet method). Effects of solvent (hexane, petroleum ether, carbondisulfide and benzen) and particle size extraction yield were investigated. Fatty acids composition of the fixed oil was determined by using GC/MS method. Volatile oils isolated by hydrodistillation (Clevenger apparatus) from the dried leaves of Laurus nobilis L.. were analyzed by GC, and main components were identified. KEYWORDS : Laurus nobilis L., Extraction, Hydrodistillation. DEFNE MEYVE VE YAPRAKLARINDAN SAB?T VE UÇUCU YA?LARIN ÇÖZÜCÜ EKSTRAKS?YONU YÖNTEM? ?LE GER? KAZANIMI ÖZET : Bu çal??mada defne meyvesinin sabit ya?? çözücü ekstraksiyonuyla (Soxhelet metodu) elde edildi. Ekstraksiyon verimine çözücünün (hekzan, petrol eteri, carbon sülfür,benzen) ve partikül boyutunun etkisi ara?t?r?ld?. Sabit ya??n ya? asitleri bile?imi ise gaz kromatografisi kütle spektrometresi kullan?larak belirlendi. Uçucu ya?lar kurutulmu? defne yapraklar?ndan su distilasyonuyla (clevenger cihaz?) izole edildi ve ba?l?ca bile?enleri gaz kromatografisi ile analiz edilerek belirlendi. ANAHTAR KEL?MELER : Defne, Ekstraksiyon, Su distilasyonu. 1, 2 Eski?ehir Osmangazi Üniversitesi, Mühendislik Mimarl?k Fakültesi, Kimya Mühendisli?i Bölümü, 26480 Bat? Me?elik,ESK??EH?R
