Muurola-4,10(14)-dien-3-one (1), 10-O-acetyl-15-oxo-alpha-cadinol (2), 15-hydroxy-alpha-cadinol (3), 4alpha-hydroxy-5beta -ethoxy-epi-cubenol (4), and 4alpha-hydroxy-5beta -acetoxy-epi-cubenol (5), five new bicyclic sesquiterpenes, have been isolated from the heartwood of Chamaecyparis obtusa var. formosana along with the known compounds epi-cubenol, T-cadinol, T-muurolol, delta-cadinol, and alpha-cadinol. The structures of the new constituents were elucidated through chemical and spectral studies.
