Abstract
Cholic-acid-type 3-keto steroids 1-8, all isolated from Deltocyathus m agnificus (2-8 after CH2N2 treatment), are the first secondary metabol ites obtained from a deep-water scleractinian, Steroids 1-3, 5, and 7 are new, their main structural oddities being loss of C(24) (see 5) or hydroxylation in the side chain (see 3 and 7). Steroids 4, 6, and 8, from the same coral, were previously known from other marine organisms .
