Targeted metabolic profiling of the revived ancient ‘Corbella’ olive cultivar during early maturation Olmo-Cunillera, Alexandra Pérez, Maria Lopez-Yerena, Anallely Abuhabib, Mohamed M. Ninot, Antònia Romero-Aroca, Agustí Vallverdú-Queralt, Anna Lamuela-Raventós, Rosa Maria Producció Vegetal Fructicultura 633 663/664 ‘Corbella’ is an ancient olive cultivar whose cultivation has recently been revived and hence little is known about its composition. This is the first work studying the metabolic profile of ‘Corbella’ olives during early maturation. Olives with a ripening index (RI) < 1 yielded considerably less oil content (<40%) but had more concentration of phenolic compounds (148.41–219.70 mg/kg), carotenoids (9.61–14.94 mg/kg) and squalene (521.41–624.40 mg/kg). Contrarily, the levels of α-tocopherol were higher at the RI of 1.08 and 1.96 (64.57 and 57.75 mg/kg, respectively). The most abundant phenolic compound was oleuropein aglycone (>50% of the phenolic composition), suggesting a high hydrolytic activity of β-glucosidase in the fruit. The antioxidant capacity was barely affected, while oleic/linoleic ratio reached its highest at RI of 1.96. Therefore, olives with an RI below 2 could be good candidates to produce high-quality olive oils with good level of stability.
