摘要新疆蔷薇属植物果实具有很高的药用和食用价值，营养成分丰富。本研究旨在研究新疆不同地区玫瑰果的元素特征。采用电感耦合等离子体质谱法（ICP-MS）测定新疆玫瑰果中K、Na、Ca、Mg、Al、Fe、Mn、Cu、Zn、Se、Sr、Cr、As、Cd、Pb、Hg的含量。采用化学计量学方法，包括雷达图分析、相关分析、主成分分析（PCA）和聚类分析（CA）对元素分析结果进行评价。结果表明，ICP-MS方法的线性度、检出限（LOD） （0.01 ~ 40.33 μg/L）、定量限（LOQ） （0.05 ~ 134.45 μg/L）、精密度（0.72 ~ 2.23%）、稳定性（0.84 ~ 2.85%）、回收率（91.81 ~ 105.57%）均符合要求。有毒元素Pb （0.00 ~ 0.65 mg/kg）、Cd （0.01 ~ 0.12 mg/kg）、As （0.03 ~ 0.49 mg/kg）、Hg （0.01 ~ 0.11 mg/kg）含量均在规定的安全限量范围内。15批新疆玫瑰果的元素分布相似，但各元素之间存在不同程度的相关性。根据综合PCA得分，一些样本的质量高于其他样本。通过聚类分析，将新疆玫瑰果分为三类。新疆玫瑰果是人体有益元素的潜在来源。
Abstract The fruit of Rosa L. plants in Xinjiang has great medicinal and edible value and are rich in nutrients. This study aimed to investigate the elemental characteristics of rose hips obtained from different Xinjiang regions. Inductively coupled plasma-mass spectrometry (ICP-MS) was used to determine the contents of K, Na, Ca, Mg, Al, Fe, Mn, Cu, Zn, Se, Sr, Cr, As, Cd, Pb, and Hg in Xinjiang rose hips. Chemometric methods, including radar plot analysis, correlation analysis, principal component analysis (PCA), and cluster analysis (CA), were used to evaluate the results of elemental analysis. The results showed that the linearity, limits of detection (LOD) (0.01–40.33 μg/L), limits of quantification (LOQ) (0.05–134.45 μg/L), precision (0.72–2.23%), stability (0.84–2.85%), and recovery (91.81–105.57%) of the ICP-MS method met the requirements. The contents of toxic elements Pb (0.00–0.65 mg/kg), Cd (0.01–0.12 mg/kg), As (0.03–0.49 mg/kg) and Hg (0.01–0.11 mg/kg) were under the prescribed safety limits. The elemental distributions of 15 batches of Xinjiang rose hips were similar, and different degrees of correlation were found among the elements. Some samples were of higher quality than the others based upon comprehensive PCA scores. The Xinjiang rose hips were divided into three categories by cluster analysis. Xinjiang rose hips are a potential source of beneficial elements for the human body.
