These wood uses as construction, furniture, and art material. The objectives of the study were ability sowang wood extract to termites (<em>Neotermes</em> sp.), white rote fungi (<em>Coriolus Versicolor</em>) and brown rot fungi (<em>Tyromyces palustris</em>). The results showed that the crude acetone and diethyl ether extract concentration 2 %, 4%, and 6% have ability to against termites, white rot and brown rot fungi. The crude acetone and diethyl ether extract at concentration 2 %, 4%, and 6% have potential as natural wood preservatives. However, n-hexane extract of sowang have ability to against termites at contraction 6%.</span></p>
