Investigation of the wood of Cunninghamia konishii resulted in the isolation and characterization of one new abietane diterpenoid, (6α,7β)-7,8-epoxy-6-hydroxyabieta-9(11),13-dien-12-one (1), and two new labdane diterpenoids, (12R)-12-hydroxylabda-8(17),13(16),14-trien-19-oic acid (2) and (12R)-12-hydroxylabda-8(17),13(16),14-trien-18-oic acid (3). The structures of these new compounds were elucidated by analysis of their spectroscopic data.
