Extraction of compounds was achieved by successive extraction using dichloromethane and methanol. Three sesquiterpene alcohols, guaiol, α-eudesmol and β-eudesmol and two monoterpene acids, (−)-citronellic acid and geranic acid, were found in the C. glaucophylla heartwood extracts based on high performance liquid chromatography (HPLC) and gas chromatography/mass spectrometry (GC/MS) analysis. Antitermitic activity of each fraction obtained from methanol extracts was demonstrated by repellent and no-choice feeding tests. One of the strong termiticidal active compounds identified was columellarin and another sesquiterpene lactone fraction showed repellent activity.
