目的:建立1种南方山葡萄酒产品的质量评价和真伪鉴别方法。方法:利用高效液相色谱分析南方山葡萄酒的单体酚类物质,建立单体酚类物质指纹图谱。采用夹角余弦法计算相关系数,对指纹图谱进行系统聚类分析。结果:“刺葡萄酒”和“桂葡1号葡萄酒”单体酚的HPLC指纹图谱相似性较差,同一品种不同年份的葡萄酒单体酚的HPLC指纹图谱具有一定的相似性。葡萄酒单体酚指纹图谱可用于区分不同品种、年份的南方山葡萄酒,是南方山葡萄酒鉴别的1种可行方法。
Objective: To establish a quality evaluation and authenticity identification method of Nanfangshan wine products. Methods: Monomeric phenols of southern mountain wine were analyzed by high performance liquid chromatography (HPLC), and the fingerprint of monomeric phenols was established. The cosine method was used to calculate the correlation coefficient, and the fingerprint was analyzed by cluster analysis. Results: The HPLC fingerprints of “Prickly Wine” and “Guigui No.1 Wine” were poor in similarity. The HPLC fingerprints of the different phenols in the same variety had certain similarities. Phenol fingerprinting of wine monomer can be used to distinguish different varieties and years of southern mountain wine, southern mountain wine identification is a feasible method.
