eng	Spatial Distinguishing of Larch Wood Samples Using Volatile Compounds Fingerprinting	Optimized headspace solid-phase microextraction combined with gas chromatography with flame ionization detector (HS-SPME-GC-FID) method was used to analyse volatile organic compounds (VOC) in multiple samples from Central Europe and Siberia. Different composition and content of VOC was found and used as a volatile compounds fingerprint. To characterized fingerprints the retention indices (RI) were calculated for each compound. Obtained RI was statistically evaluated by multivariate regression with reduction of dimensionality – orthogonal projections to latent structure (OPLS). It was able to distinguish correct origin of all 82 larch wood samples. Hence, analysis of VOC fingerprints using HS-SPME-GC-FID in combination with OPLS presents useful tool for distinguishing between wood of European larch and Siberian larch.
