In most countries the historical-cultural heritage also refers to the foods traditionally consumed. Southern Italy maintains a strong tradition of dishes based on wild plants, considered an important dietary foundation. Despite this, the nutritional properties and nutraceutical value of some of these plants are little known and, therefore, need to be investigated. Sixteen spontaneous species, traditionally used as food plants, were collected from their natural habitat in four different areas of Campania Region, and their phenolic content and nutritional value were determined according to European model of food labelling. The species analysed resulted quite homogeneous regarding the nutritional value, as demonstrated by cluster analyses. Energy values were always low. Minerals content (especially calcium and potassium) and phenols differed among the species, the sodium-potassium ratio was almost always <0.49, and phenolic content was very high for Rubus ulmifolius. Many of the wild edible plants under study may be considered a good source to dietary intakes of minerals. The species examined showed contents of nutrition values and total phenols useful for preparing mixed soups or salads in order to gain a balanced nourishment. The wild species under study can become a source of new quality horticultural products due to their nutritional and nutraceutical components.

在意大利南部（坎帕尼亚地区）收集的自发食用植物作为功能食品的机会

在大多数国家，历史文化遗产也指传统消费的食物。意大利南部保持着以野生植物为基础的强大菜肴传统，被认为是重要的饮食基础。尽管如此，其中一些植物的营养特性和营养价值鲜为人知，因此需要进行调查。从坎帕尼亚地区四个不同地区的自然栖息地收集了 16 种传统上用作食用植物的自发物种，并根据欧洲食品标签模型确定了它们的酚类含量和营养价值。正如聚类分析所证明的那样，所分析的物种在营养价值方面非常一致。能量值总是很低。不同物种的矿物质含量（尤其是钙和钾）和酚类存在差异，钠钾比几乎总是<0.49，而榆树的酚类含量非常高。许多正在研究的野生食用植物可能被认为是膳食矿物质摄入量的良好来源。检查的物种显示出营养价值和总酚含量，可用于制备混合汤或沙拉以获得均衡的营养。由于其营养成分和营养成分，所研究的野生物种可以成为新的优质园艺产品的来源。检查的物种显示出营养价值和总酚含量，可用于制备混合汤或沙拉以获得均衡的营养。由于其营养成分和营养成分，所研究的野生物种可以成为新的优质园艺产品的来源。检查的物种显示出营养价值和总酚含量，可用于制备混合汤或沙拉以获得均衡的营养。由于其营养成分和营养成分，所研究的野生物种可以成为新的优质园艺产品的来源。
