abstract: Two new 19-oxygenated polyhydroxy steroids, 24-methylcholesta-5, 24(28)-diene-3 beta, 7 beta, 19-triol-19-monoacetate (1), 24-methylcholesta-5, 24(28)-diene-3 beta, 7 beta, 19-triol-7 beta, 19-diacetate (3), together with a known steroid, 24-methylcholesta-5, 24(28)-diene-3 beta, 7 beta, 19-triol-7 beta-monoacetate (4), have been isolated from the soft coral Sinularia sp. collected from the South China Sea and characterized through interpretation of spectral data.
