Virgin olive oil phenolic profile and variability in progenies from olive crosses

Abstract: Olive breeding can indeed provide genotypes that produce oils with improved phenolic profiles as compared to traditional cultivars. In addition, the data showed that selection as a function of tyrosol content could be achieved in only one crop year. Finally, p-coumaric acid was the unique component able to discriminate between both crop years under study.

“…This cleavage might occur during the decarboxylation of oleuropein aglycon, after deglucosylation, since our previous work showed no significant increases of 3,4-DHPEA acetate in in vitro deglucosylation of oleuropein or demethoxyoleuropein by pure olive β-glucosidase [13]. On the other hand, the content of the two flavonoids identified (apigenin and luteolin) was highly correlated ( r  = 0.828), as previously reported for other breeding progenies [25], [26].…”

“…Previous reports on segregation of the content of phenolic compounds on olive oil had shown only small amount of individuals with higher values than the parents [25], [26]. Actually, data from this progeny showed to have on average a higher content of phenolic compounds than the mentioned works and other breeding selections [8], [27].…”

“…It should be noted that the progeny and progenitors were all grown in the same orchard, under the same edaphoclimatic conditions, and that the oils were extracted in exactly the same way, with no a priori criterion to select the genotypes tested on each of the three sampling years. Indeed, similar results were found when analyzing the phenolic profiles of these progeny oils [27], although it has been possible to detect the differentiation of distinct groups when a reduced number of genotypes from an olive cross were compared over consecutive years [40].…”

“…The first part of the chromatogram (see box A), is characterized by the presence of a series of simple phenols, i.e., hydroxytyrosol (peak 1), tyrosol (2), vanillic acid (3), vanillin (4). These compounds were widely described in literature [6,25,26]. The second part of the chromatogram contains numerous peaks corresponding to phenols with higher molecular weight, i.e., 3,4-DHPEA-AC (5), 3,4-DHPEA-EDA (6), p -HPEA-EDA (7), oleuropein (8), lignans (9), and 3,4-DHPEA–EA (10).…”
