[Studies on chemical constituents of marine bryozoan Bugula neritina L].
Seven compounds were isolated from the marine bryozoan Bugula neritina L. Their chemical structures were identified by NMR and MS spectroscopies as follows: cholesterol (I), cholest-4-en-3-one (II), cholesteryl myristate (III), 3beta,5alpha,9alpha-trihydrox-y-(22E,24R)-ergosta-,22-dien-6-one (IV), 3beta,5alpha,6beta-trihydroxy-(22E,24R)-ergosta-7,22-dien (V), uracil (VI), thymine (VII). Compounds II-VII were isolated from Bugula neritina L. for the first time.
