“Elemi Oil is responsible for the fresh-lemony, peppery odor of crude elemi and of elemi resinoid. The main constituent of the oil is Phellandrene, a very unstable terpene, widely distributed in the plant kingdom. Small amounts of high-boiling, oxygenated components lend character and interesting dry-out notes to this oil which is found in amounts of 25 to 28% in elemi.”
