Two diterpenes were isolated from the aerial parts of Gochnatia polymorpha var. polymorpha. Their structures were established as ent-3 beta, 19-diacetoxy-12 beta,15 alpha-dihydroxy-kaur-16-ene and ent-17,19-diacetoxy-3 beta,16 beta-dihydroxykaurane, respectively. In addition, the aerial parts afforded cycloart-25-ene-3 beta,22 alpha-diol and the flavoids genkwanin and desmethoxycentaureidin while the roots furnished taraxerol and the eudesmanolide santamarin.
