The material released was extracted with aqueous dioxane and DMF, Gel permeation chromatography of the extracts resulted in high and low molecular weight fractions. 3H and 13C NMR spectroscopic examination revealed that these fractions consisted mainly of saturated and unsaturated aliphatic compounds, alcohols, acids and esters. Aromatic substances could early be detected in very small amounts. Signals correspinding to guaiacyl, syringyl, and dilignol units were not found indicating that lignin is not prevent in the examined cork extracts.</style></abstract></record></records></xml>
