The aim of the research was to examine the antifungal activity and the most effective concentration of teak bark (Tectona grandis Linn F) extract in inhibiting wood decay fungi Schizophyllum commune Fries. Teak bark was derived from BKPH Ledok, Sambong district, Blora Regency, West Java. The Teak bark made into particle with size pass of 40 mesh and retained 60 mesh. Then one kilogram of teak bark particle was maceration with 10 liter of aquadest. The extract then mixes with potatoes dextrose agar (PDA) with several concentration i.e. 0%, 0.25%, 0.5%, 0.75% and 1% and pour into petri dish. One isolate of Schizophyllum commune was put in the center of PDA in each petri dish then incubated for nine days. The bioactive compound of extract teak bark was evaluation used phytochemical screening. Result of the research showed that teak bark extract at concentration 0.25% and 0.5% has antifungal activity values was 27.98% and 40.38% and categorized as medium inhibition growth of S. commune. Meanwhile at concentration 0.75% and 1% the AFA values was 59.94% and 65.51% categorized as strong inhibition growth of S. commune. The bioactive compounds from phytochemical screening test were alkaloid, flavonoid, terpenoid, fenolik, antrakuinon, and saponin. The extract of teak bark with concentration 0.75% and 1% are the most effective concentrations in inhibiting the growth of wood decay fungi S. commune Fries.Keywords : antifungal, phytochemical screening test, Schizophyllum commune, Tectona grandis

Abstract Cadinane-type sesquiterpenes have a wide spectrum of biological activity, but their use as wood preservatives and the structure-activity relationships of their derivatives have not yet been reported. A total of 13 compounds were synthesized from T-cadinol, T-muurolol, and α-cadinol and their chemical structures were confirmed by IR, MS, and 1H and 13C NMR. The antifungal properties of 16 compounds against three wood-decay fungi were evaluated in vitro. α-Cadinol showed strong antifungal activity against Lenzites betulina, Trametes versicolor, and Laetiporus sulphureus (total mean IC50 0.10 mM). Among the derivatives synthesized, 3β-ethoxy-T-muurolol (0.24 mM), 4ξH-cadinan-10β-ol (0.25 mM), 4ξH-muurolan-10β-ol (0.29 mM), and 4ξH-cadinan-10α-ol (0.25 mM) showed good antifungal activity against all fungi tested. Correlation was observed between the antifungal activity of the compounds tested and log P. Furthermore, the presence of an unsaturated double bond and oxygen-containing functional groups in the compounds plays a key role in their antifungal activity. The stereo configuration of cadinane-type sesquiterpenes also influences their antifungal activity. Understanding how the structure of natural compounds relates to their antifungal function is important and may facilitate their application as novel wood preservatives.

Abstract The chemical composition of the essential oil of Chamaecyparis formosensis wood has been examined. GC-MS data and retention indices for reference samples were used to identify 32 constituents. α-Eudesmol (18.06%), β-guaiene (8.0%), (–)-β-cadinene (7.89%), γ-costal (7.03%), α-muurolol (6.49%), 4α-hydroxy-4β-methyldihydrocostol (5.52%), σ-selinene (4.78%), santolina triene (4.60%), eremophilene (4.32%), humulene (4.11%), myrtenol (4.11%), and τ-cadinene (3.25%) were the most abundant components. Tests with the typical wood decay fungi, Laetiporus sulphureus and Trametes versicolor, proved the antifungal activity of the oil, as the growth of L. sulphureus and T. versicolor was inhibited at concentrations of 50 and 100 μg ml−1, respectively. The following characteristic volatile compounds were isolated and purified from ethyl acetate fractions: epi-cubenol, chamaecynone, myrtenol, cis-myrtanol, 12-hydroxyisointermedenol and 4α-hydroxy-4β-methyldi-hydrocostol. Chamaecynone possessed the strongest antifungal activity, with an antifungal index of 88.2% and 67.3% for L. sulphureus and T. versicolor at a dose of 50 μg ml−1, respectively.

Abstract Microorganism-based biological protections are alternatives to chemical treatments. Worldwide, Fusarium species are important plant pathogens, and their mycotoxins are antimicrobial. In this study, 18 Fusarium strains isolated in Korea have been investigated. Nine Fusarium species, including two unknown species, were identified based on their genotypic characteristics. Among the identified species, Fusarium armeniacum and Fusarium commune were observed for the first time in Korea. The antifungal activity of Fusarium crude extracts was assessed by growth inhibition against two wood-decay fungi and three sapstain fungi. Most Fusarium strain extracts revealed strong antifungal activity against wood-decay fungi. Strains of the unknown Fusarium sp. 2, which was found in wood samples, showed strong antifungal activity against all wood-decay and sapstain fungi tested in this study.

Influences of eight saturated aliphatic acids (C5–C10, C12, and C16) on basidiospores of four isolates of wood-decay fungi (Poria tenuis and Trametes hispida, white rot fungi, and two isolates of the brown rot fungus Gloeophyllum trabeum) were observed in vitro. Spore responses after 24 h on malt extract agar containing 10, 102 or 103 ppm of each acid included normal germination, delay of germ tube emergence, vacuolation and degeneration of spore cytoplasm, and prevention of germ tube development without spore destruction. Acids of chain length C5–C10 prevented spore germination and killed spores of all fungi at concentrations of 20–50 ppm in media, whereas other acids tested were less active. Spore germination assay of decay fungi may prove useful as a screening tool to compare potency of wood preservatives.
