A commericial sample of the oyster, Crassostrea virginica , obtained from Maryland waters of the Chesapeake Bay, contained 31 desmethylesterols and at least eight 4‐monomethylsterols. The combined gas liquid chromatography‐mass spectra of the minor components showed the presence of 6 unusual sterols, 24‐ethylcholest‐22‐en‐3β ol, 4α‐methyl‐24‐ethylcholestan‐3β‐ol, occelasterol, (24E)‐24‐propylidene‐cholest‐5‐en‐3β‐ol, (24ZO‐24‐propylidene‐cholest‐5‐en‐3β‐ol, and 24‐methylene‐cholestanol. The C‐24 configuration of 24‐ethylcholest‐5‐enol, 24‐methyl‐cholesta‐5,22‐dienol, and 24‐ethylcholesta‐5,22 dienol were elucidated by 220 MHz nuclear magnetic resonance spectrometry.
