Chemical differences between the wood extracts of jack pine (Pinus banksiana), black spruce (Picea mariana) and balsam fir (Abies balsamea) from eastern Canada

Differences in the chemical composition of the wood of balsam fir (Abies balsamea (L.)), jack pine (Pinus banksiana Lamb.) and black spruce (Picea mariana (Mill.)) were determined by GC analysis of their hexane extracts. Certain constituents such as juvabione, (E)-alpha-atlantone and delta-cadinene...

Description
Summary:Differences in the chemical composition of the wood of balsam fir (Abies balsamea (L.)), jack pine (Pinus banksiana Lamb.) and black spruce (Picea mariana (Mill.)) were determined by GC analysis of their hexane extracts. Certain constituents such as juvabione, (E)-alpha-atlantone and delta-cadinene were shown to be present only in the heartwood of balsam fir. Analysis of the sapwood of the three species also revealed the presence of certain constituents such as juvabione, dehydrojuvabione and (E)-alpha-atlantone, all found only in balsam fir and an unidentified compound found only in jack pine. The chromatograms of the hexane extracts of both sapwood and heartwood showed characteristic patterns for each of the three species of conifers.
