    Essential oil composition of the turpentine tree (Pistacia terebinthus L.) fruits growing wild in Turkey
    (ELSEVIER SCI LTD, 2009) Özcan, Mehmet Musa; Tzakou, Olga; Couladis, Maria
    Constituents of essential oils from fruit samples of the turpentine tree (Pistacia terebinthus L) collected from fifteen different localities of Turkey on August 2001 were identified by GC-MS. Twenty-eight compounds representing 92.3-100.0% of turpentine fruit oils were identified. The oil yields varied between 0.06% and 0.16%. The highest yield of oil was obtained from fruits of Antalya origin (Akbas-Serik) (0.16%). alpha-Pinene (51.3%), limonene (39.0%), p-cymen-8-ol (40.0%) and caryophyllene oxide (51.0%) were found as major components for different localities in Turkey. The predominant constituents in most samples were alpha-pinene (9.5-51.3%), limonene (tr-39.0%) and caryophyllene oxide (tr-51.5). Except for one collection (Manavgat-Antalya), which contained spathulenol (20.7%) and p-cymen-8-ol (40.0%), all the other samples yielded oils rich in a-pinene and limonene. P-Caryophyllene oxide is the most abundant compound in Hisaronu (izmir), Alanya (Antalya) and Yayladag (Hatay) oils. Results confirm the effect of locality on the oil content and composition.

    Essential Oil Composition of Turkish Herbal Tea (Salvia Aucheri Bentham Var (Canescens Boiss. & Heldr.)
    (John Wiley & Sons Ltd, 2003) Özcan, Mussa; Tzakou, Olga; Couladis, Maria
    The essential oil of the aerial parts of Salvia aucheri var. canescens, collected from two different locations (Gulnar, sample A; and Silifke, sample B) growing endemic in Turkey, were analysed by GC-MS. The oil yields of dried plants (v/dw) obtained by hydrodistillation were 1.4% and 1.7%, respectively. Forty-two compounds were identified, representing 98.6% and 99.5% of the oils from the two locations. The main constituents of the oils were: 1,8-cineole (32.3%, 28.6%), camphor (18.9%, 22.8%), borneol (8.2%, 8.9%), alpha-pinene (6.3%, 9.0%) and beta-pinene (5.3%, 6.2%), respectively. The oils consisted of monoterpenic hydrocarbons (21.3%, 27.4%), oxygenated monoterpenes (66.4%, 64.9%), sesquiterpene hydrocarbons (6.3%, 3.1%) and oxygenated sesquiterpenes (4.1%, 4.1%), respectively. 1,8-Cineole and camphor were the major components of S. aucheri. var. canescens.
