Gaharu (agarwood) oils are widely used in the fragrance industry. The quality of the oils very much depends on the appearance and long lasting aroma thus fetches higher prices. The aroma compounds in essential oils are directly influenced by the presence of complex chemical compounds that may be present in the oils. Therefore the extraction of the aroma compounds of high quality gaharu oil (JBD) was performed using a headspace solid phase microextraction (HS-SPME) which is a fast, simple and solvent free technique. Extraction of JBD oil was carried out using 100µm polydimethylsiloxane (PDMS) fiber under three different temperature conditions; 40°C, 60°C and 80°C. Analyses by GC-MS showed 28 chemical compounds (40°C), 26 compounds (60°C) and 20 compounds (80°C) were detected from the oil. Chemical compounds which may be responsible for the aroma of JBD oil is described by the presence of compounds which appear at the temperature 60°C and 80°C with the most percentage is 10-epi-Y-eudesmol, followed by y-eudesmol, ß-agarofuran and ar-curcumene.
