The structure of the previously unknown synaptogenin B, the main product of the acid hydrolysis of the triterpene oligosides synaptosides S-2 and S-3 from the holothurianSynapta maculata has been established. To prove the structure, diketones were obtained from synaptogenin B and the known stichopogenin, and their identity was shown on the basis of1H NMR and mass spectra. Synaptogenin B is a 3β-hydroxyholost-9(11)-en-23-one. It has been shown that holost-9(11)-en-3β-o1 is formed as minor component in the acid hydrolysis of the synaptosides.
