4-Desmethylsgerols in the seeds of Solanaceae

Thirteen 4-desmethylsterols: cholesterol, 24-methylcholesterol, 24-ethylcholesterol, stigmasterol, 24-methylcholesta-5,24-dienol, 24-ethylcholesta-5,24-dienol, 28-isofucosterol, 24-methylenecholesterol, cholestanol, 24-methylcholestanol, 24-ethylcholestanol, cholest-7-enol and 24-ethylcholest-22-enol, were identified in the seeds of solanaceous plants. The distribution of these 4-demethylsterols in the seeds of eleven plants among seven genera of the Solanaceae family was determined.
