To examine the antifungal activity of leaf essential oils & dominant constituents from C. osmophloeum, the essential oils of leaves from three clones (A, B, & C) collected from Haw-Lin experimental forest were extracted & their components analyzed by gas chromatography. Results from the antifungal tests demonstrated that the essential oils of both B & C leaves had strong inhibitory effects. The antifungal indices of these two leaf oils at 100ppm against five strains of white rot fungi & four strains of brown rot fungi were all 100%. Cinnamaldehyde, the major compound in C. osmophloeum leaf essential oils, possessed the strongest antifungal activities compared with the other components. Its antifungal indices against both Coriolus versicolor & Laetiporus sulphureus were 100%. The MIC (minimum inhibitory concentration) of cinnamaldehyde against C. versicolor & L. sulphureus was 50 & 75ppm, respectively. In addition, comparisons of the antifungal indices of cinnamaldehydes congeners proved that cinnamaldehyde exhibited the strongest antifungal activities. |
