Complex analytical approach to characterization of the influence of carbon dioxide concentration on carbohydrate composition in Norway spruce needles
(2007) In Journal of Chromatography A 1148(2). p.189-199- Abstract
- Water-soluble non-structural carbohydrates (NSC) in the needles of Norway spruce Picea abies [L.] Karst have been studied by using a combination of several separation techniques, having various detectors, with mass spectrometry. The intent was to find a suitable methodology that enables the characterization and determination of NSC, covering a wide range of molar masses, and being suitable to assess how NCS are influenced by both external conditions, e.g. different carbon dioxide (CO2) concentrations, light intensity, and by internal conditions such as the needle age. The techniques were liquid-liquid extraction, high performance liquid chromatography (HPLC), size exclusion chromatography (SEC), asymmetrical flow field-flow fractionation... (More)
- Water-soluble non-structural carbohydrates (NSC) in the needles of Norway spruce Picea abies [L.] Karst have been studied by using a combination of several separation techniques, having various detectors, with mass spectrometry. The intent was to find a suitable methodology that enables the characterization and determination of NSC, covering a wide range of molar masses, and being suitable to assess how NCS are influenced by both external conditions, e.g. different carbon dioxide (CO2) concentrations, light intensity, and by internal conditions such as the needle age. The techniques were liquid-liquid extraction, high performance liquid chromatography (HPLC), size exclusion chromatography (SEC), asymmetrical flow field-flow fractionation (AsFIFFF), electrospray ionization mass spectrometry (ESI-MS), and matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). NSC were extracted by a methanol/chloroform/water mixture into the water-rich phase. Application of AsFIFFF and SEC, using refractive index (RI) and multi-angle light scattering (MALS) detectors to the water-rich extracts resulted in three or four main fractions covering molar masses from 10(3) to 10(6) g/mol. Individual fractions collected from SEC were directly subjected to both MALDI and ESI-MS analysis in order to identify NSC. MALDI mass spectra confirmed the presence of hexose oligomers in individual fractions while ESI-MS was used for evaluation of low mass NSC. HPLC-RI was used for quantification of NSC and predominant carbohydrates were found to be fructose, glucose, and sucrose. The changes in their content during seasonal course were studied in detail. HPLC coupled to ESI-MS enabled the identification of low concentration NSC like raffinose that occurred in the needles of autumn samplings. An influence of the increased CO2 concentration on sucrose and glucose accumulation was observed and it was found that the light intensity as well as the needle age has significant influence on the sucrose content.
