Cupressus macrocarpa Heartwood Oil and its Bioactivity against some Wood Decay Fungi

Abstract:

Cupressus macrocarpa (Monterey cypress) heartwood has natural durability. The heartwood oil was prepared by steam distillation and its anti-fungal activity was tested against four wood decay fungi, i.e. Trametes versicolor, Irpex lacteus, Gloeophyllum trabeum, and Postia placenta with a filter paper disc method. The oil was active against all these fungi at the concentration of 8 mg.mL-1 or greater, but Postia placenta was the most difficult for the oil to inhibit. GC-MS was adopted to analyze the components of the heartwood oil. Two components, 4-terpineol and carvacrol were identified and carvacrol represented 94.428% of the oil. The oil had anti-fungal activity mostly because of carvacrol in the high content
