摘要
利用中药色谱图分析和数据管理系统和SPSS 19.0统计分析软件进行聚类分析,研究法国、南非、澳大利亚等10个常见葡萄酒产地85份红葡萄酒样品的气相色谱指纹图谱。结果表明:不同国家的红葡萄酒气相色谱指纹图谱存在差异,不同产地生产的红葡萄酒气相色谱峰的相对峰面积和数量不同,各自产地红葡萄酒气相色谱有其特征峰;初步建立了基于气相色谱指纹图谱进行产地溯源的系统聚类分析识别模式和方法,聚类分析表明,10个不同产地红葡萄酒可以很好地聚类和区分;通过对市面上购买的2种红葡萄酒商品进行了产地假冒模式的应用实验,发现该系统聚类分析识别模式可以进行初步的判别,判别效果较好。结果表明该气相色谱指纹图谱法是产地假冒红葡萄酒进行初步甄别的一种有效方法。
In order to discriminate among red wines according to their geographical origins, the GC fingerprint profiles of 85 samples from 10 main producing countries such as France, South Africa and Australia were cluster analyzed by using a chromatographic analysis and data management system for traditional Chinese medicines （TCMs） and statistical analysis software SPSS 19.0. A classification model was established for discriminant analysis of the grographic origin of red wines. The results showed that among red wine samples from different countries, there were differences in GC fingerprints mainly in terms of the relative peak area and the number of peaks, suggesting that each sample from different origins has characteristic GC peaks. The results of cluster analysis showed that 10 geographic origins could be classified effectively. Two commercial red wines were analyzed by using this method. One of them might be from France and the other might be from Italy. The established method proves to be effective at discriminating among red wines according to their geographical origins based on GC fingerprint profiles.
