Summary:Two new 19-oxygenated polyhydroxy steroids, 24-methylene cholest-5-en-1α,3β,19-triol (1) and 24-methylene cholest-5-en-3β,7β,9α,19-tetrol (2), and three known steroids, ergost-5,24(28)-dien-3β,19-diol (litosterol), cholest-5-en-3β,7β,19-triol, and ergost-5,24 (28)-dien-3β,7β,19-triol, have been isolated from the soft coral Nephthea chabroli and characterized through interpretation of spectral data.
