Characterization of the Volatile Compounds of the Hardwood Portion of Betula papyrifera Marshall From Quebec, Canada.

ABSTRACT: Betula papyrifera Marshall (paper birch) hardwood is an abundant yet underutilized resource for Quebec's forestry industry. We investigated the volatile compounds of the hardwood extracted using hydrodistillation (HD) and headspace solid-phase microextraction (HS-SPME) and analyzed them by gas chromatography-mass spectrometry (GC-MS) and GC-flame ionization detection. HD produced an essential oil with a low average yield (0.010% ± 0.001%), from which we identified 51 compounds, dominated by linoleic acid and its oxidation products. HS-SPME provided a complementary profile, with 50 compounds identified, including aromatics and sesquiterpenes absent from the essential oil. The findings suggest that direct valorization of B. papyrifera hardwood for its volatile secondary metabolites is limite
