A new steroid was isolated from the ethyl acetate extract fraction of marine sponge Cinachyrella australiensis collected from the South China Sea. Its structure was determined by IR, 1H NMR, 13C NMR, MS, DQCOSY, NOESY, TOCSY, HMQC and HMBC as (3E)-cholest-4-en-3,6-dione-3-oxime (1). Bioassay showed that compound 1 was cytotoxic against Hep G2. The spectral data were reported in details in this paper.
