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, 6β, 9α, 19 -tetrol by variety of spectral analysis such as IR, EIMS, 1DNMR, 1H-1H COSY, HMQC, HMBC, NOESY.
