【摘要】 用高效液相色谱法(HPLC)分析了17种云南产烤烟型烟叶中多酚类物质,并定量测定了7种主要烟草多酚物质,用模式识别方法处理了HPLC测定多酚的谱图轮廓数据,计算了这些烟叶之间的颜色相似性标度参数TK值,并与人工感官结果进行了比较。结果表明,通过用模式识别技术处理多酚的HPLC轮廓数据,可以定量表征不同等级云南烟叶之间的颜色相似性。模式识别方法处理与感官评价结果基本一致,但前者更客观。因此,模式识别技术可以作为客观评价烟叶颜色质量、弥补人工感官方法的工具。更多还原

【Abstract】 Polyphenols in seventeen Yunnan flue-cured tobacco leaves were assayed by high performance liquid chromatography(HPLC).The major seven tobacco polyphenols were quantitatively determined.HPLC polyphenol profiles were processed by pattern recognition(PRM).The values of color similarity criterion TK among these tobacco leaves were calculated and compared with human organoleptic color assessment.It was shown that data from PRM based on HPLC profiles of polyphenols could be used to quantitatively characterize color similarity among Yunnan tobacco leaves of different grades.The results by PRM and by organoleptic assessment were compatible.The former was more objective.更多还原
