The yields of the fractions of n-hexane-soluble, ethyl acetate-soluble and methanol-soluble from the P. densiflora sawdust were obtained 1.36%, 2.21% and 4.03% using organic solvents, respectively (Table 1). The antifungal activity of the n-hexane extracts against L. edodes at concentrations 125, 250, 500, 750 and 1000 ppm were 36.5%, 41.2%, 43.1%, 45.4% and 47.6%, respectively (Table 2). The percent of antifungal activity against L. edodes was the greatest for the n-hexane extracts, ranging from 36.5% to 47.6% at a concentrations of 125 ppm to 1000ppm, with the values for all concentrations significantly different from one another. In this experiment, the antifungal activity by the n-hexane extracts was the highest. This result supposed that the n-hexane extracts have not only many more inhibitory compounds against L. edodes than the ethyl acetate and methanol extracts but also the inhibitory compound may be more easily dissolved by n-hexane than by ethyl acetate or methanol.
