  2. 1. Biotransformations of Turpentine Constituents : Oxygenation and Esterification

    Author : Marica Lindmark-Henriksson; KTH; []
    Keywords : Picea abies; Pinaceae; Essential oils composition; Terpene alcohol; Hemiacetal; Hemiacetal ester; TMP-turpentine; Monoterpene; alpha-pinene; beta-pinene; Limonene; Verbenol; Pinocarveol; Borneol; Myrtenol; Suspension cell culture; Biotransformation; ;

    Abstract : This thesis describes methods to obtain value–addedcompounds from TMP-turpentine obtained from the spruce, Piceaabies. The methodology focuses on biotransformations using twoapproaches: an oxygenation approach (i.e. oxygenation ofterpene hydrocarbons by cell cultures) and an esterificationapproach (i. READ MORE

  4. 2. Internal rotation in molecules : a nuclear magnetic resonance relaxation study

    Author : Anders Ericsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In order to study the internal rotation of methyl-type groups in molecules, the carbon-13 nuclear magnetic resonance (NMR) spin-lattice relaxation times (T1) and nuclear Overhauser enhancement factors (n) are measured for some terpenes (borneol, camphor, isopinocampheol and α-pinene), for octafluorotoluene and for 1-methylnaphtalene. In addition, deuterium NMR T1 data are presented for 1-methylnaphtalene-d10. READ MORE

    Abstract : The species of Amomum Roxb. (Zingiberaceae) in Cambodia, Laos and Vietnam are revised. Thirty-five species and two varieties are recognised, all names are typified, and detailed descriptions and a key are provided. Nine new species are described and one species is validated. READ MORE

  6. 4. Odours attracting Medetera (Diptera) predators to spruce bark beetles in a multitrophic system

    Author : Maria Sousa; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Tree-killing bark beetles cause great economic and ecological damage worldwide. Several long-legged fly species of the genus Medetera are natural enemies of tree-killing bark beetles and are of interest as potential biological control agents. READ MORE
