Abstract:
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 component analysis (PCA) and discriminant analysis (DA) – to handle oil content and fatty acid composition data of these samples, showed that is possible to cluster the samples in two groups according to their origins. Beja oil samples are characterized by higher oleic (C18:1), palmitoleic (C16:1) and palmitic acid (C16:0) contents, while oil samples from Sesimbra are richer in linoleic (C18:2), linolenic (C18:3) and C20:1 acids. However, only myristic and oleic acids showed to have discriminant power among samples from different origins. The different edapho-climatic conditions of the regions affected the variability of fatty acid composition of cardoon seed oil.
