不同产地浮小麦HPLC指纹图谱研究

    HPLC fingerprint of Fructus Tritici Levis from different producing areas

    • 摘要: 通过建立浮小麦指纹图谱,研究不同产地浮小麦质量差异,为药食两用浮小麦的质量控制和开发利用提供理论依据。采用高效液相色谱分析,建立浮小麦HPLC指纹图谱。利用“中药色谱指纹图谱相似度评价系统(2012版)”对不同产地浮小麦进行相似度评价,使用SPSS软件进行聚类分析(CA)和主成分分析(PCA)。结果表明:通过相似度评价,建立了浮小麦指纹图谱,共标记出16个共有峰,12批样品相似度为0.936~0.996。聚类分析将安徽、河北、河南、山东和山西地区浮小麦聚为一类;广西、四川地区浮小麦聚为一类;黑龙江地区浮小麦聚为一类。主成分分析能把不同产地浮小麦分开,与聚类分析结果基本一致。该方法具有较高的准确度、稳定性和可靠性,可用于浮小麦质量控制。

       

      Abstract: By establishing Fructus Tritici Levis fingerprints, the differences in the quality of Fructus Tritici Levis from different producing areas were studied, which provided a basis for the quality control and development of edible and medicinal Fructus Tritici Levis. HPLC analysis was performed to establish HPLC fingerprints of Fructus Tritici Levis. The similarities of Fructus Tritici Levis samples were evaluated by the software "Similarity Evaluation System for Chromatographic Fingerprint of TCMs (2012 version)". Cluster analysis (CA) and principal component analysis (PCA) were performed using SPSS software. The results showed that through the similarity evaluation, the fingerprint of Fructus Tritici Levis was established and 16 common peaks were marked, and the similarity of 12 batches of samples was 0.936-0.996. Cluster analysis results showed that Fructus Tritici Levis from Anhui, Hebei, Henan, Shandong, and Shanxi into were classified into one category. Those from Guangxi and Sichuan were clustered into one category, and those from the Heilongjiang region were clustered into one category. Principal component analysis could separate Fructus Tritici Levis from different producing areas, which is basically consistent with the cluster analysis results. The method has high accuracy, stability, and reliability,which can be used for the quality control of Fructus Tritici Levis.
