摘　　要：对贺兰山东麓产区生产的有机和非有机葡萄酒的元素含量和稳定C、N同位素比值分布特征进行分析,并利用此数据对宁夏贺兰山东麓地区有机与非有机葡萄酒进行甄别。结果表明,有机与非有机葡萄酒在一些金属元素如Na、Mg、K、Al和Cu的含量上具有显著差异,而且有机葡萄酒的乙醇和丙三醇的δ^(13)C值显著低于非有机葡萄酒,但δ^(15)N显著高于非有机葡萄酒。利用C、N稳定同位素和一些金属元素含量,结合主成分分析,可对贺兰山东麓地区有机和非有机葡萄酒进行有效区分,为我国有机葡萄酒掺假检测以及该地区的葡萄酒产业发展提供技术支撑,具有重要的应用前景。In this study,we analyzed elemental contents and stable isotope ratios of carbon(C)and nitrogen(N)in organic and non-organic wines from Helan mountain east region in Ningxia of China and then used the obtained data to distinguish between the two wines.Our results showed that there were significant differences in the contents of several metal elements including Na,Mg,K,Al and Cu between the organic and non-organic wines and that theδ13C ratios of ethyl alcohol and glycerol in the organic wine were much lower than those in the non-organic one,but the N stable isotope ratios were significantly higher than those in the non-organic one.Thus,C and N stable isotopes and the contents of selected metal elements could be used to effectively distinguish between organic and non-organic wines by principal component analysis.This method has a great potential to be applied for organic wine authentication and therefore can provide a technical support for the development of the wine industry in this region.
