Olives and olive products are particularly important for the national agroindustrial sector, for the aspects related to the production territory (authenticity), and for the link with the Mediterranean Diet. Several studies indicate that the elemental profile of olive and olive products depends on the production area in which the olive trees were grown, and the elemental content of the olives can be used as a marker of the production area. In order to confirm this hypothesis, the multi-elemental profile of olive drupes and olive leaves of eleven cultivars arising from two different production areas was evaluated through ICP-MS and ICP-AES techniques. In addition, some leaf samples were analysed by LPAS in order to evaluate the applicability of this new analytical technique for determining the geographic origin. The obtained results, combined with chemometric tools, showed the possibility of discriminating samples according to the production area on the basis of the elemental content, as well as by LPAS.
橄榄及橄榄产品对于国家农业产业部门、与生产地域相关的方面（真实性）以及与地中海饮食的联系而言尤为重要。多项研究表明，橄榄及橄榄产品的元素谱取决于橄榄树生长的产区，且橄榄的元素含量可作为产区的标志。为了证实这一假设，通过电感耦合等离子体质谱法（ICP-MS）和电感耦合等离子体原子发射光谱法（ICP-AES）技术评估了来自两个不同产区的11个品种的橄榄核果和橄榄叶的多元素谱。此外，对一些叶片样本进行了激光诱导击穿光谱分析（LPAS），以评估这种新分析技术用于确定地理来源的适用性。所得结果结合化学计量工具表明，根据元素含量以及通过LPAS，有可能依据产区对样本进行区分。
