Descripción
Four outstanding Cynara cardunculus L. plants were selected from two field experiments located in Sesimbra (Portugal) and Alcalá de Henares (Spain), and used for vegetative propagation, producing four clones. In this work, two plants from each clone were collected. The plant stalks were separated as depithed stalks (DPS) and pith (P) samples, for lignin characterization by Py-GC/MS(FID). The lignin derivative compounds with more expression were: 4-vinylsyringol (with values from 1.8% to 5.7%), 4-propenylsyringol (1.7% to 2.5%), syringol (0.63% to 1.9%), 4-methylguaiacol (0.56% to 1.7%), 4-vinylguaiacol (0.21% to 1.1%). The total lignin represented in average 23.9% in DPS, slightly higher than in the P samples (21.8%). The syringyl-units were predominating in both DPS and P, with average values of respectively, 12.6% and 13.9%. The DPS samples presented more guaiacyl-units (11.1%), while in P samples only 7.9% was attained. The p-hydroxyphenyl units represented less than 2.0% in both. Overall, Cynara was characterized by an SG type of lignin, where in average the S/G ratio was 1.3 and 2.1, respectively for DPS and P
