Sesquiterpene alcohols from Chamaecyparis obtusa leaf oil

Abstract Three new sesquiterpene alcohols were found in the hexane extract of Chamaecyparis obtusa leaf oil and the structures were elucidated as 10-epi-cubebol, β-hinokienol and α-hinokienol. The absolute configuration of the last two alcohols was established by synthesis from (−)menthone.
