Abstract

Six new cadinane‐type sesquiterpenes, (1__β__,4__β__,5__α__,10__α__)‐1,4‐epoxymuurolan‐5‐ol (1), (4__α__,10__β__)‐4,10‐dihydroxycadin‐1(6)‐en‐5‐one (2), (2__β__,3__α__,4__β__,6__β__)‐2,3‐dihydroxycadin‐1(10)‐en‐5‐one (3), (2__β__,3__α__)‐α‐corocalene‐2,3‐diol (4), (7__S__)‐α‐calacoren‐14‐ol (5), and (8__β__,9__β__,10__β__)‐8,9‐epoxycalamenene‐3,10‐diol (6) together with one known compound, (8__β__,9__β__,10__β__)‐8,9‐epoxycalamenen‐10‐ol (7), were isolated from the roots of Taiwania cryptomerioides. The structures of the new constituents were essentially elucidated by spectral evidence.
