New paper published – Volatile Organic Compounds Emitted by Plants Determination using New Gas Chromatography Mass-Spectrometry Methods

Our work group´s “Romanian branch”, led by Lucian Copolovici had published a methods paper, suggesting two novel methods how to capture and measure volatile organic compounds in plants, together with Astrid Kännaste and Ülo Niinemets from our lab.

Abstract

In the nature, plants emit numerous volatile organic compounds. Common plant volatiles include various green leaves volatiles, terpenes, phenylpropanoids and/or benzenoids. In the present paper it will be characterized thermal desorption (TD) and solid phase microextraction methods (SPME) for simultaneous determination of green leaves volatiles (GLVs), various mono- and sesquiterpenes in headspace of plants. The first method is based on preconcentration of VOCs on solid absorbents coupled with the gas chromatograpy mass-spectrometry coupled with thermal desorption system (GCMS-TD). For trapping the volatile organic compounds (VOC) we used a multibead tube filled with solid sorbents (Carbotrap c and Carbopack c). Different types of solid sorbents have been tested and characterised. The second method is based on adsorption of different volatile compounds on the fibres followed by GC-MS analyses. The fibres trapped and released volatile organic compounds with different numbers of carbons atoms. Both methods have been used for volatile organic compounds emitted by plants from Betulaceae family.
