Extractive-free cork (Cork), suberin, desuberized cork (Cork<jats:sub>sap<\/jats:sub>), and milled-cork lignins (MCL) from Cork and Cork<jats:sub>sap<\/jats:sub>were isolated. Suberin composition was determined by GC-MS\/FID, whereas the polymers structure in Cork, Corksap, and MCL was studied by Py-TMAH and 2D-HSQC-NMR. Suberin contained 94.4% of aliphatics and 3.2% of phenolics, with 90% of \u03c9-hydroxyacids and \u03b1,\u03c9-diacids. FA represented 2.7% of the suberin monomers, overwhelmingly esterified to the cork matrix. Py-TMAH revealed significant FA amounts in all samples, with about 3% and 6% in cork and cork lignins, respectively. Py-TMAH and 2D-HSQC-NMR demonstrated that cork lignin is a G-lignin (&gt;96% G units), with a structure dominated by \u03b2\u2013<jats:italic>O<\/jats:italic>\u20134\u2032 alkyl-aryl ether linkages (80% and 77% of all linkages in MCL and MCL<jats:sub>sap<\/jats:sub>, respectively), followed by phenylcoumarans (18% and 20% in MCL and MCL<jats:sub>sap<\/jats:sub>, respectively), and smaller amounts of resinols (ca. 2%) and dibenzodioxocins (1%). HSQC also revealed that cork lignin is heavily acylated (ca. 50%) exclusively at the side-chain \u03b3-position. Ferulates possibly have an important function in the chemical assembly of cork cell walls with a cross-linking role between suberin, lignin and carbohydrates.<\/jats:p>","DOI":"10.1515\/hf-2015-0014","type":"journal-article","created":{"date-parts":[[2015,5,22]],"date-time":"2015-05-22T11:22:57Z","timestamp":1432293777000},"page":"275-289","source":"Crossref","is-referenced-by-count":52,"title":["Ferulates and lignin structural composition in cork"],"prefix":"10.1515","volume":"70","author":[{"given":"Ant\u00f3nio Velez","family":"Marques","sequence":"first","affiliation":[{"name":"Instituto Superior de Engenharia de Lisboa, Rua Conselheiro Em\u00eddio Navarro 1, 1959-007 Lisboa, Portugal"}]},{"given":"Jorge","family":"Rencoret","sequence":"additional","affiliation":[{"name":"Instituto de Recursos Naturales y Agrobiolog\u00eda de Sevilla, CSIC, P.O.
