The wood constituents of Taiwania cryptomerioides Hayata, indigenous to Taiwan, was found to be rich in sesquiterpene alcohols by K. Kafuku and R. Kato. We reinvestigated the neutral portion of the steam volatile from acetone extract of the wood and were able to isolate eight sesquiterpenes and fifteen sesquiterpene alcohols. These sesquiterpenes were identified as α-cedrene, β-cedrene, γ-cadinene, calamenene, α-cadacorene, cadaleme, α-muurolene, and γ-munrolene. Eleven of the fifteen sesquiterpene alcohols have been identified as α-cadinol, δ-cadinol, T-cadinol, T-muurolol, cedrol, epi-cubenol, cadinan-3-en-9α-ol-2-one, muurolan-3-en-9β-ol-2-one, muurolan-2α-, 9β-diol-3-ene, muurolan-2β, 9β-diol-3-ene, and cadinan-3α, 4α 9α-triol. Two additional saturated sesquiterpene diols, one (XVII) from n-hexane extractive and the other (XVIII) from acetone extractive of the woods were obtainted more recently. The structure of these two diols (XVII, XVIII) as well as the newly revised structure of ζ-cadinol (VII) have been elucidated by conventional chemical and spectroscopic methods.
