Seventy‐six samples of saffron were analysed through inductively coupled plasma‐mass spectrometry (ICP‐MS) and stable isotope ratio analysis. The dataset was formed by 67 samples harvested in different areas of Italy, Morocco and Iran, and nine samples purchased in the Italian market. For the first time, 42 elements and five stable isotopes (δ¹³C, δ¹⁵N, δ³⁴S, δ²H and δ¹⁸O) were considered to carry out the discrimination of the samples on the basis of their geographical origin. Combined ICP‐MS and isotopic composition data turned out to be a useful tool for the geographical discrimination of saffron among predefined cultivation sites.

稳定的同位素比分析与电感耦合等离子体质谱联用，可对意大利和国外藏红花进行地理区分。

通过电感耦合等离子体质谱法（ICP-MS）和稳定同位素比分析对76种藏红花样品进行了分析。该数据集由在意大利，摩洛哥和伊朗不同地区收获的67个样本以及在意大利市场上购买的9个样本组成。首次，42个元件和五个稳定同位素（δ ¹³ C，δ ¹⁵ N，δ ³⁴ S，δ ² H和δ ¹⁸ O）被认为是进行样品的与其地理来源的基础上鉴别。结合使用ICP-MS和同位素组成数据证明是在预定的种植地点之间对藏红花进行地理区分的有用工具。
