Isolation and Identification of Cyclooctasulfur From the Octocoral Sinularia humilis(van Ofwegen, 2008)

Chemical examination of the octocoral Sinularia humilis, collected in the waters of Taiwan, led to the isolation of S8(1). Its structure was determined by a single-crystal x-ray diffraction analysis and this is the first time that S8has been reported from a marine invertebrate.
