Two new sterol have been isolated from the South China Sea marine organism.Compound 1 was isolated from the sponge Polymastia sobustia and compound 2 was obtained from the soft coral Sinularia inexplicata. Their structures were established as 3β-hydroxy-stigmast-5en-7-one and 24 - methylene cholestan -3β, 66, 9α,19 -tetrol by variety of spectral analysis such as IR, EIMS, 1DNMR, 1H-1H COSY HMQC, HMBC, NOESY.
Two new sterols have been isolated from the South China Sea marine organism. Compound 1 was isolated from the sponge Polymastia sobustia and compound 2 was obtained from the soft coral Sinularia inexplicata. Their structures were established as 3β-hydroxy-stigmast-5en-7- one and 24-methylene cholestan -3β, 66, 9α, 19 -trol by variety of spectral analysis such as IR, EIMS, 1DNMR, 1H-1H COZY HMQC, HMBC, NOESY.
