EVALUATION OF EXTRACTIVE FROM MAHOGANY (Swietenia macrophylla) SEEDS AGAINST WOOD DECAYING FUNGI

Many plant derivatives substances have fungitoxic, pecticidal and insecticidal ability. Mahogany (Swietenia macrophylla) seeds are very popular in this respect for a decade of time. In this study to investigate the fungi toxic activities of mahogany (S. macrophylla) seeds against wood decay fungi. Organic solvents were used to remove extractives from mahogany seeds sample. The solvents were used ethyl alcohol and methyl alcohol. The solvents were removed by roto-evaporation. The toxicity of various extracts concentration was used in laboratory condition and natural condition to prove the effectiveness against fungal growth in the test sample. Three different concentration solvents were applied both in laboratory condition and natural condition. Both results revealed that highest concentration of ethanol extract (30%) is most effective against fungus growth. From this study, it was summarized that mahogany seed extract is potential source of eco-friendly wood preservatives.
