General description
α-Terpinene (1-isopropyl-4-methyl-1,3-cyclohexadiene, TER) is a monoterpene found in various plant volatile oils. It is commonly employed as flavoring additive in foods and beverages, as fragrance in cosmetics, and as scent in household products.[1] Embryofoetotoxic potential of TER in the rat has been reported. It is also useful in the preparation of folk medicine potions.[2] It is one of the major component of the essential oil of Melaleuca alternifolia.[3] It reacts with singlet oxygen to form the endoperoxide, ascaridole along with p-cymene and hydroperoxides.[4]
