Separation and analysis of steryl and wax esters from Dicranum elongatum
Abstract Complete separation of the steryl and wax esters in the subarctic moss Dicranum elongatum was achieved on MgO thin‐layer plates without any notable alteration of the acyl and alkyl moieties of the esters. Gas chromatography‐mass spectrometry of the hydrolyzed fraction showed that the sterol...
