Abstract

Five new uncommon polyoxygenated steroids, namely suberoretisteroids A–E (1–5), were isolated from the gorgonian Suberogorgia reticulata, never studied so far. The structures and relative configurations of these new compounds were elucidated on the basis of extensive spectral analysis. This work led to the structural revision of some steroids previously found in the Indian gorgonian Gorgonella umbraculum.
