title: Sterol composition of a cultured marine dinoflagellate, Heterocapsa circularisquama.
abstract: The composition of sterols was determined in a cultured marine dinoflagellate Heterocapsa circularisquama. Ten kinds of the sterol in H. circularisquama were identified by capillary gas chromatography-mass spectrometry. The major sterol was a 4-methyl sterol, 4alpha,23,24-trimethyl-5alpha-cholest-22E-en-3beta-ol (dinosterol) which is the common sterol in many dinoflagellates.
