Chemometric Characterization of Cardoon Oil from Large-Scale Productions in Portugal

H. Pereira, J. Gominho & S. Ferreira-Dias
Large scale cultivation of cardoon (Cynara cardunculus L.) for biomass production, in a total of 84 ha, was installed in two different regions in southern Portugal (Beja and Sesimbra). The seeds collected in different plants (17 composite samples) presented an oil content varying from 21.4% to 26.1 % (dry basis) and the chemical analysis showed that cardoon oil is rich in linoleic (61.5%), oleic (22.8%) and palmitic (11.1%) acids. The use of chemometric techniques -principal...
