The nutrient profiling of green leafy vegetables is largely concentrated on biochemical assays and their elemental composition is often overlooked. At the same time, the investigation of the elemental composition of plants is essential, as they are required in several metabolic processes for the normal growth and development of the human body and their deficiency can lead to several clinical disorders. In this paper, we consider the potential of the synchrotron-radiation-induced energy dispersive X-ray fluorescence spectroscopy technique as a rapid, sensitive, and simultaneous multielemental detection tool to investigate the elemental composition of different elements present in some leafy vegetables: dill, fenugreek, mustard, and chenopodium. The X-ray fluorescence spectrа of the leaves of dill, fenugreek, mustard, and chenopodium were excited by synchrotron X-ray radiation having an energy of 15 keV and recorded in the energy range <20 keV. The recorded spectrum shows the presence of potassium, calcium, manganese, iron, nickel, copper, zinc, arsenic, and selenium with varying concentrations in different leafy vegetables. PyMca software was applied to determine the concentration of the various detected elements. The relative quantitative comparison of the detected elements shows that chenopodium leaves are a rich source of potassium among all the leafy vegetables studied. The leaves of mustard and chenopodium are abundant in calcium, while the leaves of dill and fenugreek have a higher content of trace elements like manganese, iron, copper, nickel, selenium and zinc. Herein, the role of the detected elements in human and plant health is also described.

绿叶蔬菜的营养分析主要集中在生化分析上，而它们的元素组成往往被忽视。同时，对植物元素组成的研究是必不可少的，因为它们在人体正常生长和发育的几个代谢过程中是必需的，它们的缺乏会导致多种临床疾病。在本文中，我们考虑了同步辐射诱导能量色散 X 射线荧光光谱技术作为一种快速、灵敏和同时多元素检测工具的潜力，用于研究一些叶菜类蔬菜中不同元素的元素组成：莳萝、胡芦巴、芥末和藜。莳萝、胡芦巴、芥菜叶的 X 射线荧光光谱，和 chenopodium 被具有 15 keV 能量的同步加速器 X 射线辐射激发并记录在 <20 keV 的能量范围内。记录的光谱显示钾、钙、锰、铁、镍、铜、锌、砷和硒在不同叶类蔬菜中的浓度各不相同。应用 PyMca 软件来确定各种检测元素的浓度。检测元素的相对定量比较表明，藜叶是所有研究的叶类蔬菜中钾的丰富来源。芥菜和藜的叶子富含钙，而莳萝和胡芦巴的叶子锰、铁、铜、镍、硒和锌等微量元素含量较高。在此，还描述了检测到的元素在人类和植物健康中的作用。
