Abstract : Antifungal activities of 6 methanol extract obtain from bark, sapwood and heartwood of Syzygium chlorantha and Hopea spp. were evaluated against the white rot fungi Pycnoporus sanguineus using a medium in which homogenised hyphae were dispersed. It is observed that Hopea spp. has antifungal activity against Pycnoporus sanguineus compared to Syzygium chlorantha. Hopea spp. bark showed the highest antifungal activity against Pycnoporus sanguineus with reaction showed very clear inhibition zone. Meanwhile, Hopea spp. sapwood showed partially clear inhibition zone. On the other hand, there are no antifungal activities occurring at heartwood of Hopea and all parts of Syzygium chlorantha. The positive control glycyrrhizic acid dipotassium salt (GADS) showed clear inhibition zone from 50 µg to 1000 µg. The results of the sapwood and bark of Hopea spp. suggest that these extract have great potential as a source of fungi stats.
