Abstract

antifungal activity

China-fir heartwood

extractives

components

wood preservatives

Three extractives from China-fir were obtained by a sequential extraction processes with hexane, ethyl acetate, and methanol. The components of the three extractives were analyzed: (1) The gas chromatography-mass spectrometry (GC-MS) analysis showed that in addition to the presence of cedrol, naphthalenes comprised a relatively large percentage of both the hexane extract (10.39%) and the ethyl acetate extract (9.43%). (2) Total phenolic contents analysis showed that phenols took up 6.66 % of the ethyl acetate extract and 22.8% of the methanol extract. All extracts, even with low concentrations, presented fair antifungal activities against two white-rot fungi, Trametes versicolor and Irpex lacteus and two brown-rot fungi, Postia placenta and Gloeophyllum trabeum. Cedrol and naphthalenes were partly responsible for the bioactivities. The synergistic effect of phenols and antifungal compounds also contributed to the wood decay resistance.
