Description

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. Hinokitiol has inhibitory effects on Chlamydia trachomatis and may be clinically useful as a topical drug.

The name originates from the fact it was originally isolated in Taiwanese hinoki in 1936. 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.
