Hinokitiol (β-thujaplicin) is a natural monoterpenoid found in the wood of trees in the family Cupressaceae. It is a tropolone derivative and one of the thujaplicins.[2] Hinokitiol has inhibitory effects on Chlamydia trachomatis and may be clinically useful as a topical drug.[3][4]

The name originates from the fact it was originally isolated in Taiwanese hinoki in 1936.[5] It is actually almost absent in Japanese hinoki while it is contained in high concentration (about 0.04% of heartwood mass) in Juniperus cedrus, Hiba cedar wood (Thujopsis dolabrata) and Western red cedar (Thuja plicata). It can be readily extracted from the cedarwood with solvent and ultrasonication.[6]
