Two new labdane-type diterpene aldehydes, 15-oxolabda-8(17),11(Z), 13(E)-trien-19-oic acid (1) and 15-oxolabda-8(17),11(Z), 13(Z)-trien-19-oic acid (2), and a new nordrimane-type sesquiterpene, 12-oxo-11-nordrim-8-en-14-oic acid (3), along with a known diterpene, 15-nor-14-oxolabda-8(17),12(E)-dien-19-oic acid (4), were isolated from the stem bark of Thuja standishii. The structures of 1-3 were established by spectroscopic methods.
