New additional triterpenoids from the Mediteranean sponge Raspaciona aculeata

Here we reported the finding of eight additional raspacionins (13-20) from the Mediterranean sponge Raspaciona aculeata. The structure determination was obtained by spectroscopic techniques, mainly by 1D and 2D nuclear magnetic resonance. We performed biological tests as antifeedant and ichthyotoxicity assays; moreover we reported some preliminary cytotoxicity test with MCF-7 tumoral cell line.
