Abstract

Kajian potensi ekstraktif daripada daun, buah, kayu, kulit, bunga and biji Pong Pong (Cerbera odollam) sebagai pengawet kayu dalam menentang kulat dan anai anai telah dijalankan. Penilaian sifat anti kulat ekstraktif pada tahap awal yang diekstrak dengan heksana, etil asetat, etanol dan metanol telah dikaji melalui kaedah anti kulat kertas turas. Kandungan bahan kimia terkandung dalam ekstrak yang aktif semasa anti kulat telah dianalisis melalui komatografi gas spektrometer jisim. Kadar kematian anai anai terhadap ekstraktif yang diekstrak dengan metanol telah dinilaikan. Kesan ekstraktif terhadap kayu padu getah termasuk pereputan disebabkan oleh kulat pereputan, anai anai dan kajian tanam dalam tanah telah dikaji. Kesan ekstraktif terhadap papan serpai termasuk pereputan disebabkan oleh kulat, pengembangan ketebalan, kekuatan ikatan dalaman dan pembebasan formadehid papan serpai, pereputan disebabkan oleh anai anai dan kajian tanam dalam tanah telah dikaji. This research investigated the potential of extracts from leaf, fruit, wood, bark, flower and seed of Pong Pong (Cerbera odollam) as wood preservatives against fungal and termite. Preliminary evaluation of antifungal properties of n-hexane, ethyl acetate, ethanol and methanol extracts was evaluated via paper disc antifungal assay. Chemical compounds of antifungal active extracts were analysed via gas chromatography mass spectrometer. Termite mortality of methanol extracts was evaluated. The effect of extracts to solid Rubberwood including fungal decay, termite decay, and soil burial were evaluated.
