Chemical investigation of the root bark of Turraeanthus mannii and the stem of T. longipes resulted in the isolation of two new diterpenes, 13-methyl-labda-8(17)-en-15-oic acid (1) and 13-(hydroxymethyl)-14-hydroxy- ent-labda-8(17)-en-15-oic acid (2), along with two known diterpenes, 19-hydroxy- ent-labda-8(17),13-dien-15,16-olide (3) and 19-acetoxy- ent-labda-8(17),13-dien-15,16-olide (4), and the phytosterol, stigmasterol. The structure elucidation of the new compounds has been achieved using spectroscopic techniques.
