Abstract

Flower waters, also known as aromatic waters, hydrosols, or herbal distillates, are typically considered to be by-products of essential oil. However, because of their bioactive content, flower waters currently exhibit various applications in the food industry as flavoring agents and food sanitizers. In this study, inductively coupled plasma–atomic emission spectrometry (ICP-AES) was employed for the assessment of the elemental composition (i.e., Ag, Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb, and Zn) of several flower waters. The reported method was optimized and validated in terms of linearity, limits of detections (LODs), limits of quantifications (LOQs), accuracy, and precision. The relative recoveries of the proposed method were between 80.0% and 120.0%, while the relative standard deviation values were less than 9.8%. The LODs and LOQs of the ICP-AES method ranged between 0.8 μg L⁻¹(Cr) - 73.5 μg L⁻¹ (Al), and between 2.5 μg L⁻¹ (Cr) - 245.0 μg L⁻¹ (Al), respectively . The validated ICP-AES method was successfully employed for the analysis of a variety of flower water samples.

摘要

花水，也称为芳香水、纯露或草药馏出物，通常被认为是精油的副产品。然而，由于它们的生物活性成分，花水目前在食品工业中作为调味剂和食品消毒剂具有各种应用。在这项研究中，电感耦合等离子体原子发射光谱法 (ICP-AES) 用于评估元素组成（即 Ag、Al、B、Ba、Ca、Cd、Co、Cr、Cu、Fe、Mg、几种花水中的 Mn、Ni、Pb 和 Zn)。报告的方法在线性、检测限 (LOD)、定量限 (LOQ)、准确度和精密度方面进行了优化和验证。该方法的相对回收率在 80.0% 和 120.0% 之间，而相对标准偏差值小于 9.8%。^-1 (Cr) - 73.5 μg L ^-1 (Al) 和 2.5 μg L ^-1 (Cr) - 245.0 μg L ^-1 (Al) 之间。经验证的 ICP-AES 方法成功用于分析各种花卉水样。
