title: A new C26 sterol peroxide from the opisthobranch mollusk Adalaria sp. and the sea pen Virgularia sp.
abstract: 5,8 alpha-Epidioxy-(22E)-24-nor-5 alpha-cholesta-6,22-dien-3 beta-ol (8 approximately) has been isolated from the sea pen Virgularia sp. and has been observed as a component of a mixture isolated from the opisthobranch mollusk Adalaria sp. The structure of 8 approximately was deduced from spectroscopic data. A further six sterol peroxides isolated from Adalaria and six from Virgularia were tentatively identified on the basis of spectroscopic analysis of mixtures.
