Thujaplicins (isopropyl cycloheptatrienolones) are series of related chemical substances discovered in the 1930s and isolated from Thuja plicata (western redcedar tree).[1] The three compounds are α-thujaplicin, β-thujaplicin (hinokitiol), and γ-thujaplicin. They are known for potent anti-fungal and anti-bacterial properties.[2] They are also known to be potent antioxidants.[3] They were the first natural tropolones to be made synthetically, by Ralph Raphael and colleagues.[4]
