The Efficacy of Methanolic Extract of Eucalyptus tereticornis Sm. Leaves against Wood Decaying Fungi

The present study was carried out to investigate the efficacy of Eucalyptus tereticornis leaves extract against wood decaying white rot (Trametes versicolor) and brown rot (Oligoporus placentus) fungi. Methanolic extract at 0.5, 1.0 and 1.5% concentration levels were tested against Trametes versicolor and Oligoporus placentus by potato dextrose agar bioassay. Results revealed that the methanolic extract of Eucalyptus tereticornis leaves at 1.5% concentration exhibited complete inhibition of Trametes versicolor. However, 17.21% growth of Oligoporus placentus was recorded in treated petri plates at 1.5% concentration of extract. Qualitative analysis of the methanolic extracts revealed presence of appreciable amount of terpenoids, phenols, flavonoids, alkaloids, carbohydrates and tannins.
