Headspace solid-phase microextraction--comprehensive two-dimensional gas chromatography of wound induced plant volatile organic compound emissions.

摘要: Plant emissions of volatile organic compounds from mechanically wounded Agrostis stolonifera, Pennisetum clandestinum, Eucalyptus leucoxylon and Trifolium repens have been sampled by headspace-solid phase microextraction (HS-SPME) analysed using comprehensive two-dimensional gas chromatography (GCxGC) for measurement the plant emissions. GCxGC produces a fingerprint in 2D separation space that may be approximately interpreted as boiling point-polarity space, then presented contour plot. This allows identification sample-dependent variations component distributions plot, which will contain information about differences should therefore facilitate recognition different materials displays gross volatiles between each species.
