Cadinane-type sesquiterpenes from the roots of Taiwania cryptomerioides HAYATA

Abstract

Five new cadinane-type sesquiterpenes, 15-acetoxy-T-muurolol (1), isokhusinodiol (2), cadin-10(14)-ene-4β,5α-diol (3), cadinane-4β,5α,10β-triol (4), and muurolane-4β,5α, 10β-triol (5), together with five known compounds, T-cadinol (6), T-muurolol (7), α-cadinol (8), δ-cadinol (9), and khusinodiol (10), were isolated from the roots of Taiwania cryptomerioides. The structure of the new constituents were elucidated through chemical and spectral studies. © 2003 Pharmaceutical Society of Japan.
