目的 利用电子鼻和电子舌技术对辛味中药、物质组群、单体的嗅觉、味觉(即气、味)进行表征,建立辛味中药的药味物质基础分析的方法。方法 选用代表性的5种辛味中药,以药材、物质组群及单体成分作为待测样品,对样品的嗅觉及味觉进行电子鼻及电子舌检测,采用主成分分析法对数据进行分析。结果 电子鼻主成分分析结果中,各个样品能很好地被区分,识别指数为98,具有明显辛味的成分归为一类;电子舌主成分分析结果中,不同滋味的样品在图中分布位置不同。结论 电子鼻及电子舌能够对中药样品进行区分,结合主成分分析及药物功效,可以对药物物质组群的嗅觉及味觉进行初步的表征。

Objective To characterize the smell and taste of pungent-taste herbs, material group, and simplex components by using the electronic nose and electronic tongue, and establish the method of material basis of pungent-taste herbs. Methods Five pungent-taste herbs, material group, and simplex components were chosen as samples, and measuring by electronic nose and electronic tongue. The data collected with the tongue was evaluated with principal component analysis (PCA). Results In the PCA consequence of electronic nose, different samples were obviously distinguished, and discrimination index was 98. The samples with visibly pungent-taste composition were clustered. In the PCA consequence of electronic tongue, the different taste sample had a different position. Conclusion Electronic nose and electronic tongue are capable of discriminating between samples, which could character the smell and taste of material group with PCA and function.
