Abstract
Three new triterpenoids, sodwanones A-C (1-3) have been isolated from the sponge Axinella weltneri The structure of compound 1 was unambiguo usly determined by X-ray diffraction studies. All H-1 and C-13-NMR res onances of 1 were assigned by an extensive use of ID and 2D NMR techni ques. The structure of 2 and 3 were determined by comparison of their spectral data and mainly by NMR with those of 1.
