Abstract

Kajian dilakukan untuk mengetahui kandungan aktiviti antioksidan, jumlah fenol dan sifat-sifat antikulat yang terdapat di dalam kayu keras di Malaysia yang dipilih secara rawak. Spesies kayu yang terlibat di dalam kajian ini ialah keranji kuning kecil, durian, gerutu-gerutu, machang-machang, medang kemangi, medang daun lebar, sesendok, meranti pipit, meranti sarang punai, petai-petai, meranti melantai, ara berteh bukit, chengal, kembang semangkok jantung, mempelam, mersawa kuning and mersawa kuning kecil. Setiap sampel diasingkan kepada 3 bahagian iaitu kulit, kayu teras dan kayu gubal. Kaedah yang digunakan untuk mengetahui kandungan antioksidan ialah, dengan menggunakan 1, 1-diphenyl-2-picrylhydrazyl (DPPH), manakala kandungan fenol ditentukan dengan menggunakan kaedah Folin-Ciocalteu. The antioxidant activities, total phenolic compound and antifungal activities were investigated from selected Malaysian hardwood species. The species studied include keranji kuning kecil, durian, gerutu-gerutu, machang-machang, medang kemangi, medang daun lebar, sesendok, meranti pipit, meranti sarang punai, petai-petai, meranti melantai, ara berteh bukit, chengal, kembang semangkok jantung, mempelam, mersawa kuning and mersawa kuning kecil. All samples were divided into 3 parts; bark, heartwood and sapwood.
