Effect of Port Orford cedar cone extracts on mould and decay fungi

Abstract

Steam distilled essential oil extracts from Port Orford cedar (Chamaecyparis lawsoniana) cones were evaluated for their ability to inhibit the growth of Aspergillus niger and a Trichoderma spp. as well as for their ability to inhibit fungal degradation of wood by Gloeophyllum trabeum, Postia placenta or Trametes versicolor. The extract limited growth by A. niger at the highest dilution level tested (5%) but failed to limit fungal degradation. The results suggest that cone extracts from this species have limited potential for producing bioactive compounds.
