Abstract

Two independent literature searches were conducted for extraction and identification of fragrant chemicals found in sandal wood. A total of eleven relevant research articles were selected from over twenty five articles. The combined results of the two studies are reported in this presentation. Different species of sandal wood trees are found mainly in the Pacific Ocean countries and Indian subcontinent. Varying fragrant chemicals are found in these trees from different regions. Traditional extraction methods, including steam distillation and hydro-distillation, were employed to extract essential oils from sandal wood. Two other methods employing microwave assisted distillation and supercritical fluid (SCF) CO2 extraction also yielded satisfactory yields of essential oils. The separation and identification of fragrant components were conducted by employing gas chromatography-mass spectrometry techniques (GC-MS) in all studies. Two dimensional gas chromatography-flame ionization detection techniques (GC-FID) were used in two studies for separation followed by mass spectrometry for identification. Infrared spectroscopy was also employed for identification of functional groups in the fragrant chemicals. Major fragrant components of essential oils of sandal wood are (Z)-a-santalol, (Z)-b-santalol, epi-b-santalol, a-santaldiol, b-santaldiol, (Z)-a-trans-bergamotol, (Z)-nuciferol, The components with highest concentrations in the sandal wood essential oils are (Z)-a-santalol and (Z)-b-santalol, with approximately over 40% and 15% concentrations, respectively. The next major components with lesser concentrations are (Z)-a-trans-bergamotol, epi-b-santalol, and a-santaldiol, with approximately 5%, 3%, and 3% concentrations, respectively. Other components usually have concentrations of less than 1%. Detailed results of concentrations of fragrant components in sandal wood will be presented.
