Description

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.[87] Embryofoetotoxic potential of TER in the rat has been reported. It is also useful in the preparation of folk medicine potions.[88] It is one of the major component of the essential oil of Melaleuca alternifolia.[89] It reacts with singlet oxygen to form the endoperoxide, ascaridole along with p-cymene and hydroperoxides.[15]

Application

α-Terpinene (1-Isopropyl-4-methyl-1,3-cyclohexadiene, p-Mentha-1,3-diene) has been used in a study to evaluate the antifungal properties of Melaleuca alternifolia essential oil (tea tree oil, TTO). It was identified as one of the principal component of the essential oil of M. alternifolia.[89]
