1. Antifungal activity of water extracts The antifungal activity of the water extracts against L. edodes was proportional to the concentration of the water extracts. The antifungal activity of the water extracts at 1000 ppm was the highest among the tested concentration against L. edodes mycelia. The antifungal activity were significantly different from each concentration of the water extracts. Therefore, it can be concluded that the water extracts of the P. densiflora sawdust have inhibitory compounds to the growth of L. edodes mycelia. 2. Yield and antifungal activity of fractions from water extracts The powdered water extracts was further treated serially using organic solvents in order to separate the water extracts into the fractions of n-hexane-soluble, ethyl acetate-soluble, methanol-soluble and methanol-insoluble. The ethyl acetate-soluble fraction showed much higher antifungal activity than the other fractions. The antifungal activity of the ethyl acetate-soluble fraction against L. edodes at 1000 ppm showed a statistically significant difference in the fractions of n-hexane-soluble, ethyl acetate-soluble, methanol-soluble and methanol-insoluble. And, there was not significantly difference between the antifungal activities of the n-hexane-soluble and methanol-soluble fractions at 1000 ppm. 3. Antivungal activity of fractions of organic solvent extracts The fractions were isolated from each organic solvent by the silica-gel column chromatography and then the fractions were confirmed and divided on the values of Rf by the thin-layer chromatography. The fractions were produced six band of the n-hexane, nine band of the ethyl acetate and eight band of the methanol extracts. The HIII fraction from the n-hexane extracts showed the highest growth inhibition against L. edodes mycelium.
