α-Santalol
α-Santalol is an organic compound that is classified as a sesquiterpene. It comprises about 55% of the oil of sandalwood, another less abundant component being β-santalol. As of 2002, about 60 tons of sandalwood oil are produced annually by steam distillation of the heartwood of Santalum album. It is a valued component for perfumes.[1]
