Essential oils (EOs) were extrcated from some non-timber forest products (NTFPs) namely: Canarium luzonicum (Blume) A. Gray resin and Canarium ovatum Engl. resin commonly called Manila elemi, Cinnamomum mercadoi S. Vidal leaves and Eucalyptus camaldulensis Dehnh. leaves using the FPRDI developed bench-scale extractor. They were characterized by FTIR spectroscopy and GC-MS analysis. In addition, their antimicrobial activities were also determined. Based from GC-MS analysis, the major components of C. luzonicum (Blume) A. Gray resin essential oil (CLREO) were DLimonene (49.71%), myristic acid (19.67%) and palmitic acid methyl ester (16.99%). On the other hand, major components of C. ovatum Engl. resin essential oil (COREO) were limonene (43.41%) and alpha-phellandrene (32.42%). Both limonene and alpha phellandrene compounds were present in both resins but alpha phellandrene is more abundant in COREO. The GC-MS chromatogram C. mercadoi S. Vidal leaf EO showed 12 components which were mostly monoterpenes and sesquiterpenes compounds. The most abundant component of the leaf oil was methyleugenol (42.61%), a phenylpropanoid, followed by betha-Linalool (38.23%), a monoterpenoid. Results also showed that volatile oils of cinnamon leaves, Manila elemi resin and Eucalyptus leaves have good antimicrobial activities against various gram-positive and gram-negative bacteria including pathogens.
