| Common Name | beta-Thujaplicin |
|---|
| Description | Beta-Thujaplicin, also known as hinokitiol or β-thujaplicin, belongs to the class of organic compounds known as tropolones. Tropolones are compounds containing tropone ring with a hydroxyl group at ring position 2. A monoterpenoid that is cyclohepta-2,4,6-trien-1-one substituted by a hydroxy group at position 2 and an isopropyl group at position 4. Beta-Thujaplicin is an extremely weak basic (essentially neutral) compound (based on its pKa). Beta-Thujaplicin is a phenolic and woody tasting compound. Outside of the human body, beta-Thujaplicin has been detected, but not quantified in, fruits. beta-Thujaplicin is found in Calocedrus formosana, Chamaecyparis obtusa, Cupressus abramisiana, Cupressus abramsiana, Cupressus lusitanica , Cupressus sargentii, Cupressus tricuspidata, Cupressus macrocarpa, Juniperus communis , Juniperus conferta, Juniperus taiwaniana, Thuja occidentalis, Thuja plicata and Thujopsis dolabrata. beta-Thujaplicin was first documented in 1948 (PMID: 18118412). This could make beta-thujaplicin a potential biomarker for the consumption of these foods (PMID: 10973816) (PMID: 15917561) (PMID: 17927050) (PMID: 18379073) (PMID: 23312825) (PMID: 12554707). |
