Garcinia (Clusiaceae) species are traditionally used as flavoring agents in curries and to cure several human health complications. This study investigated 31 macro, micro, and trace elements in microwave-assisted digested samples of Garcinia cambogia fruit and its anti-obesity commercial products by inductively coupled plasma-optical emission spectroscopy (ICP-OES) and inductively coupled plasma-mass spectrometric (ICP-MS) techniques. The methods were also validated using the coefficient of determination (R ), limits of detection and quantification (LOD, LOQ), precision (CV%), analysis of certified reference materials, spiking recovery experiments, and participation in an accredited laboratory proficiency test organized by Food Analysis Performance Assessment Scheme (FAPAS).
Quality assurance confirmed that the methods were efficient and in accordance with criteria set by the Association of Official Analytical Chemists (AOAC). In the elemental analysis, the analyzed macro, micro, and trace essential elements were present in appreciable concentrations, which could meet the human nutritional requirements. Traces of toxic elements were within safe limits.
From the results of the current study, the fruit and its commercial products could be considered potential sources of mineral elements without posing any threats to consumers. © 2018 Society of Chemical Industry.
藤黄科（Clusiaceae）的一些物种被传统用作咖喱调味料，并用于治疗多种人类健康并发症。本研究采用微波辅助消解样品，利用电感耦合等离子体发射光谱（ICP-OES）和电感耦合等离子体质谱（ICP-MS）技术对藤黄果果实及其商业减肥产品中的 31 种宏量、微量和痕量元素进行了分析。该方法还通过测定系数（R）、检出限和定量限（LOD、LOQ）、精密度（CV%）、分析认证参考物质、加标回收实验以及参与由食品分析性能评估计划（FAPAS）组织的认可实验室能力验证来进行验证。
质量保证证实该方法有效且符合官方分析化学家协会（AOAC）设定的标准。在元素分析中，所分析的宏量、微量和痕量必需元素以可观的浓度存在，可满足人体营养需求。痕量有毒元素也在安全范围内。
根据目前的研究结果，该果实及其商业产品可被视为矿物质元素的潜在来源，对消费者没有任何威胁。 © 2018 化学工业协会。
