    has caused severe damage to more than 100 tree species in Taiwan. The aims of this study were to investigate the antifungal activities of Taiwania heartwood extracts against P. noxius and to identify the antifungal compounds. Antifungal activities were examined using the agar dilution method (a direct contact assay) and the inverted lid method (a vapor contact assay). Active compounds were purified using liquid-liquid partition, open-column chromatography and HPLChplcSubject Category: Techniques, Methodologies and Equipment

    . Among four soluble fractions (n-hexane, ethyl acetate, n-butanolbutanolSubject Category: Chemicals and Chemical Groups

    and water soluble fractions), results showed that n-hexane soluble fraction (HSF) can significantly inhibit the growth of P. noxius via the agar dilution method. Moreover, active compounds present in HSF were obtained using antifungal assay-guided fractionation. Results showed that ferruginol, T-cadinol, α-cadinol and T-muurolol were found to exhibit excellent antifungal activities against P. noxius, and their IC50 values were 16.9, 25.8, 33.8 and 50.6 µg/mL, respectively.
