Abstract :
Three new diterpenoids, tricalysiolide H (1) and tricalysiones A (2) and B (3), with novel structural features were isolated from the wood of Tricalysia dubia, together with a known compound, cafestol (4). The structures of 1–3 were elucidated on the basis of 2D NMR spectroscopy and X-ray crystallographic analysis.
