title: [Study fo sterols from brown seaweeds of the genus Cytoseira. Identification by gas-liquid chromatography coupled with mass spectrometry (author's transl)].
abstract: All the samples of brown seaweeds (Cystoseria) that we have studied present the same deltas sterols fucosterol, 22 trans-dehydrocholesterol, brassicasterol, 24-methylene cholesterol as well as cystosterol, a new C27 sterol. This sterol has been submitted to gas-liquid chromatographic-mass spectrometric analysis.
