Phytochemical Characterization of Olea europaea L. Cultivars of Cilento National Park (South Italy) through NMR-Based Metabolomics

A metabolomics-based study identified five olive cultivars—Racioppella, Guglia, Pizzulella, Oliva amara, and Racioppa—as particularly rich in health-promoting phenolic compounds within the Cilento National Park. The research used NMR spectroscopy to analyze 19 autochthonous cultivars, revealing significant variability in their phytochemical profiles. This suggests potential for metabolic fingerprinting as a tool for cultivar differentiation, though further studies are needed to assess environmental influences on these chemical traits.
