Lipophilic Extractives in Heartwood of European Larch (Larix decidua Mill.)

The heartwood of two European larch trees was examined for the content of lipophilic extractives. Hexane was used as a solvent for extractions, while gas chromatography with flame ionisation detection and gas chromatography coupled to mass spectrometry were applied for analyses. Different lipophilic...
