α-Terpineol is a monoterpene alcohol. It is one of the components responsible for the antifungal activity in Melaleuca alternifolia (tea tree) essential oil.[1] The reaction rate constant of α-terpineol with the OH radical and ozone was found to be (1.9±0.5)×10-10cm3 molecule-1s-1 and (3.0±0.2)×10-16cm3 molecule-1s-1, respectively. α-Terpineol is a monoterpene alcohol.
