Abstract
A preliminary study to evaluate naturally durable wood species in an above ground field trial using Gas Chromatography-Mass Spectrometry (GC-MS) detected differences in fatty acid extractives between species and within the same species over time. Fatty acids were extracted with chloroform: methanol mixture then methylated with sodium methoxide and fractionated using solid phase extraction columns. Fatty acids were identified, quantified with known standards, and compared between wood species. Future analysis of exposed specimens will determine longevity of extractives and correlate changes to the initial extractive content.
