¹H Nuclear Magnetic Resonance (NMR) spectroscopy coupled with multivariate analysis has been applied in order to investigate metabolomic profiles of more than 200 extravirgin olive oils (EVOOs) collected in a period of over four years (2009-2012) from different geographic areas. In particular, commercially blended EVOO samples originating from different Italian regions (Tuscany, Sicily and Apulia), as well as European (Spain and Portugal) and non-European (Tunisia, Turkey, Chile and Australia) countries. Multivariate statistical analysis (Principal Component Analisys (PCA) and Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA)) applied on the NMR data revealed the existence of marked differences between Italian (in particular from Tuscany, Sicily and Apulia regions) and foreign (in particular Tunisian) EVOO samples. A possible correlation with available climate data has been also investigated. These results aim to develop a powerful NMR-based tool able to protect Italian olive oil productions.

氢核磁共振（¹H NMR）光谱结合多变量分析已被用于研究在四年多时间（2009 - 2012年）内从不同地理区域收集的200多种特级初榨橄榄油（EVOO）的代谢组学特征。具体而言，包括源自意大利不同地区（托斯卡纳、西西里和普利亚）以及欧洲（西班牙和葡萄牙）和非欧洲（突尼斯、土耳其、智利和澳大利亚）国家的商业混合EVOO样品。对NMR数据应用多变量统计分析（主成分分析（PCA）和正交偏最小二乘判别分析（OPLS - DA））揭示了意大利（特别是来自托斯卡纳、西西里和普利亚地区）和外国（特别是突尼斯）EVOO样品之间存在显著差异。还研究了与可用气候数据的可能相关性。这些结果旨在开发一种强大的基于NMR的工具，以保护意大利橄榄油生产。
