    Essential oils from dried aerial parts of Salvia officinalis L. and Salvia fryticosa Mill. Provided from Bosnia-Herzogoviena (Sarajova) and Turkey (Mugla) were analysed using gas chromatography-mass spectrometry (GC-MS). The air dried plant materials were subjected to hydrodisfiliation for 4 h using a Clevenger type apparatus to give yellow oils in 1.76% (S. officinalis) and 1.39% (S. fruticosa), respectively. Thirty-one and fourty constituents were identified in the oils of both plants, representing 96.33 and 98.23% of the total oil. While alpha-pinene (9.65%), camphene (9.46%), eucalyptol (9.18%), thujone-cis (24.59%) and camphre (23.06%) were established as major constituents of S. officinalis L., alpha-pinene (3.62%), camphene (5.26%), camphre (26.76%), borneol (8.91%) and eucalyptol (40.11%) were found as major constituents of S. fruticosa

    The effect of harvest periods on chemical composition of essential oil of mint (Mentha spicata L.) leaves
    (AGRIMEDIA GMBH, 2015) Figueredo, Gullies; Chalchat, Jean Claude; Chalard, Pierre; Al Juhaimi, Fahad Y.; Ghafoor, Kashif; El Babiker, El Fachl; Özcan, Mehmet Musa
    The essential oils of mint leaves (Mentha spicata L.) cultivated in Middle Anatolia were extracted by hydrodistillation, and analysed by GC and GC-MS. The percentage yields of the essential oils of mint harvested in different months (from May to December) were 1.2%, 2.5%, 2.75%,3.0%, 2.0%, 3.7%, 2.6% and 2.0%, respectively. The major constituents varied depend on harvest periods. The main constituents of mint oil were carvone (30.8-62.9%), dihydrocarveol (2.7%-22.4, iso dihydrocarvyle acetate (12-14.4%), limonene (5.2-17.2%) and eucalyptol among the months.
