thujaplicin n. /-ˈplʌɪsɪn/ [ < Latin plic-ātus, past participle of plicāre to fold] any of three isomers of isopropyltropolone, C₃H₇·C₇H₅O₂, that have fungicidal properties and occur in the conifer Thuja plicata.

1948 Erdtman & Gripenberg in Nature 8 May 719/2 The compound, m.p. 82°, is termed γ-thujaplicin because the isopropyl group occupies the γ-position in the cycloheptatrieneolone.

1964 New Scientist 4 June 613/1 The tropolones beta thujaplicin and gamma thujaplicin were highly toxic to the four test basidiomycetes.

1978 Further Perspectives Org. Chem. 29 He did visualize the formation of simpler natural tropolones—the thujaplicins—by ring expansion in some unknown way from a benzene ring and an attached carbon.
