The sterol composition of Spheciospongia vesparia from the Caribbean Sea is reported. Three groups of sterols, Δ 5 , Δ 0 , Δ 5,7 , were found. The isolated 5α,8α‐epidioxy sterols appeared to be predominantly, if not exclusively, artifacts. The auto‐oxidation of native Δ 5,7 ‐sterols to 5α,8α‐epidioxy sterols has been investigated. A transformation of dietary Δ 5 ‐sterols to Δ 5,7 ‐sterols has been demonstrated in Spheciospongia vesparia . © 1998 SCI
