Identification par CPG/SM des principaux acides gras constitutifs de la subérine du liège

The aim of this work was to verify the presence of cork (Quercus Suber) in two samples of linoleum of the beginning of the twentieth century. Using GC/MS after acidic methanolysis and silylation, it was possible to identify most of the components of a modern sample of cork. The dominant is a lipid polymer: the suberin. Its monomeric composition is examined in details.
