Marine sterols. VI(1). Sterols of the scallop, Patinopecten yessoensis.
The sterols of the scallop, Patinopecten yessoensis Jay, was found to contain over 20 components. The major components were delta5-sterols, and lesser amount of ring-saturated sterols were also present. Biogenetically unusual C26 sterols (24-norcholesta-5,22-dien-3beta-ol and 24-norcholest-22-en-3beta-ol) and 24(28)-cis-24-propylidenecholest-5-en-3beta-ol (29-methylisofucosterol), 22-trans-27-nor-(24S)-24-methylcholesta-5,22-dien-3beta-ol (occelasterol), and a new sterol, 22-trans-27-nor-(24S)-24-methylcholest-22-en-3beta-ol (patinosterol), were isolated and their structures were confirmed. Occurrence of 22-trans-(24S)-24-methylcholesta-5,22-dien-3beta-ol (24-epibrassicasterol) was confirmed. 22-cis-Cholesta-5,22-dien-3beta-ol was not found.
