Trace elemental analysis, besides its ability to determine stable isotopes ratios, represents a possible complementary tool useful to differentiate wines based on their regional origins. Wines and their provenance soils from two major wine producing areas in Southeast Romania ('Valea Calugareasca' and 'Murfatlar'), and also wine from the region of Moldova (Eastern Romania) were analyzed by inductively coupled plasma mass spectrometry (ICP-MS), and statistical data of elemental composition was used to differentiate these wines according to grape type and geographical origin. Moreover, this study gathers relevant elemental trace composition of wines produced in most important Romanian vineyards, thus offering a useful wine differentiation tool by their production district. The results show that the differentiation of Romanian wines according to their provenance is based on the following main elements: Ni, Ag, Cr, Sr, Zn, and Cu for Valea Calugareasca, Rb, Zn, and Mn for Murfatlar, and Pb, Co, and V for Moldova.
微量元素分析除了能够测定稳定同位素比值外,还可能是一种有用的补充工具,可根据葡萄酒的产地来区分其种类。本研究采用电感耦合等离子体质谱法(ICP-MS)对罗马尼亚东南部两个主要葡萄酒产区(“Valea Calugareasca”和“Murfatlar”)的葡萄酒及其产地土壤,以及摩尔多瓦(罗马尼亚东部)的葡萄酒进行了分析,并利用元素组成的统计数据根据葡萄品种和产地对这些葡萄酒进行了区分。此外,该研究还收集了罗马尼亚最重要的葡萄酒产区的相关微量元素组成,为按产区对葡萄酒进行区分提供了一种有用的工具。结果表明,根据产地对罗马尼亚葡萄酒进行区分的主要依据是以下元素:Valea Calugareasca 产区的 Ni、Ag、Cr、Sr、Zn 和 Cu,Murfatlar 产区的 Rb、Zn 和 Mn,以及摩尔多瓦产区的 Pb、Co 和 V。
