L. has been studied for its potential nutraceutical properties. Quantitative and qualitative analyses were conducted on samples of Madural, Verdeal, and Cobrançosa elementary leaves and leave sprouts () collected in the region of Valpaços, Portugal. Mineral analysis determined the measurements of the levels of several macro- and micro-elements based on ICP-MS techniques. The inorganic analysis in this work allowed us to propose olive leaf extract (OLE) from different cultivars as a viable and affordable source of mineral substrates to address disorders related to essential elements such as Na, K, Mg, Ca, Mn, Fe, and Cu deficiencies. Given the importance of the research on novel therapies, finding a suitable substrate for extracting quality amounts of mineral is a priority. The physiological influence of enzymes dependent on minerals with regard to neuroinflammatory and neurobehavioral, metabolic, cardiovascular, osteodegenerative, anti-aging, pulmonary, and immunological defense disorders might dictate the importance of further research for designing supplementation based on the nutraceutical potential of OLE of these cultivars predominant in the northern region of Portugal.
人们已经对L. 的潜在营养保健特性进行了研究。对在葡萄牙瓦尔帕索斯地区采集的马杜拉尔、韦尔代尔和科布兰索萨初生叶及叶芽样本进行了定量和定性分析。矿物分析基于电感耦合等离子体质谱技术测定了几种常量和微量元素的含量。这项工作中的无机分析使我们能够提出，来自不同品种的橄榄叶提取物（OLE）是一种可行且经济实惠的矿物底物来源，可用于解决与钠、钾、镁、钙、锰、铁和铜等必需元素缺乏相关的疾病。鉴于新型疗法研究的重要性，找到一种合适的底物来提取高质量的矿物质是当务之急。依赖矿物质的酶对神经炎症和神经行为、代谢、心血管、骨退行性、抗衰老、肺部和免疫防御疾病的生理影响，可能决定了基于葡萄牙北部地区这些主要品种OLE的营养保健潜力来设计补充剂的进一步研究的重要性。
