    Satureja. parnassica Heldr.et Sart. subsp. sipylea P.H. Davis is a subspecies endemic to Turkey. The anatomical, morphological, ecological and chemical features of S. parnassica subsp. sipylea have been investigated. Plant samples were collected from different regions in Turkey. The morphological features of various organs of the plant such as leaf and flower are described in detail. In anatomical studies, transverse sections of the plant stem and leaf have been examined and supported by illustration and photographs. Ecological studies provide information about the physical and chemical structure of soil types in Spil Mountain and Marmara Island. The chemical composition of the essential oil of aerial parts of the plant was examined

    Essential oils obtained by microdistillation from seven endemic Centaurea species [C. hierapolitana Boiss., C. cadmea Boiss., C. calolepis Boiss., C. cariensis Boiss. subsp. maculiceps (O. Schwarz) Wagenitz, C. cariensis Boiss. subsp. microlepis (Boiss.) Wagenitz, C. ensiformis P.H. Davis and C. reuterana Boiss. var. reuterana] and three widespread (C. cyanus L., C. depressa Bieb. and C. urvillei DC. subsp. urvillei) Centaurea L. (Asteraceae) taxa from Turkey were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS) techniques. A total of 158 different compounds were identified. Significant and quantitative differences were observed among the species. Hexadecanoic acid (19.5–33.4%) was the main constituent of C. hierapolitana, C. cadmea, C. calolepis, C. reuterana var. reuterana, C. depressa and C. urvillei subsp. urvillei oils, while carvacrol (13.0–28.4%) was the major compound in, C. cariensis subsp. microlepis, C. cariensis subsp. maculiceps, C. ensiformis and C. cyanus oils. © 2008, Taylor & Francis Group, LLC.

    Abstract: The essential oil obtained by hydrodistillation from Ranunculus marginatus var. trachycarpus (Ranunculaceae) from Turkey was analyzed by GC and GC-MS. Thirty-six compounds were characterized in the oil of R. marginatus var. marginatus. Main compounds were ?-terpinyl acetate (18.9 %), phytol (11.1 %), hexadecanoic acid (10.0 %) and ß-sesquiphellandrene (8.7 %). © 2014, Har Krishan Bhalla & Sons

    The essential oils of the leaves and seed of Dryobalanops aromatica Gaertn. obtained by hydrodistillation resulted in 0.07% and 1.89% yield, respectively. These oils were then examined by GC-MS. Eighty-three components (plus an unknown) were identified from the leaf oil, representing 92% of the oil. Oxygenated monocyclic monoterpenes (terpinen-4-ol 15%, α-terpineol 16%), bicyclic monoterpene (α-pinene 7%) and oxygenated bicyclic sesquiterpene (globulol 8%) were the major constituents. In the case of the seed oil, 31 components were identified, representing 100% of the oil, while acyclic monoterpene (myrcene 5%), monocyclic monoterpene (limonene 6%), bicyclic monoterpenes (α-pinene 41%, α-thujene and b-pinene 13% each, sabinene 6%), and bicyclic sesquiterpene (bicyclogermacrene 6%) made up the major components. The remaining constituents of each oil (54% and 10%, respectively) were found to be minor (≤4% each). The chemical compositions of both oils differed quantitatively but showed important qualitative similarities and differences. The results of this study serve as the first report of complete chemical profiles of both oils

    PubMedID: 15030215The effects of maturation (green, pink, and ripe) on phenolic composition of strawberry cultivars Camarosa, Dorit, Chandler, and Osmanli and their hybrids were investigated using a high-pressure liquid chromatography (HPLC) method, p-Hydroxybenzoic acid, p-coumaric acid, ellagic acid, cyanidin-3-glucoside, pelargonidin-3-glucoside, kaempferol, quercetin, and myricetin were individually quantified for each stage. The highest amounts of anthocyanins were obtained from ripe fruits whereas ellagic acid was found as the main phenolic in the green fruits. Phenolic concentrations were found statistically different in green and ripe fruits. One hybrid was found to have higher phenolic contents than the other genotypes. The p-hydroxybenzoic and p-coumaric acid levels changed during maturation, but no differences in contents of flavonoids in green and ripe fruit were detected
