摘　　要：利用电子鼻、电子舌技术对不同等级白术药材进行鉴别研究。应用Loading分析法对电子鼻传感器区分样品的能力进行分析,应用主成分分析(PCA)、线性判别分析法(LDA)分析不同等级白术药材电子鼻信号值,单因素方差分析电子舌获取的甜味值。结果显示电子鼻LDA与PCA分析均可有效区分不同等级白术样品;电子舌能够客观测定不同等级白术药材“味”的变化参数,三个等级白术药材的甜味有差异。Electronic nose and electronic tongue were used to identify Atractylodes macrocephala from different grades.The ability of electronic nose sensor to distinguish samples was analyzed by using the method of loading analysis,the signal value of electronic nose of different grades of Atractylodes macrocephala was analyzed by principal component analysis(PCA),linear discriminant analysis(LDA),and the sweetness value of electronic tongue was analyzed by single factor variance method.The results showed that LDA and PCA analysis could effectively distinguish the samples of different grades of Atractylodes macrocephala,electronic tongue could objectively determine the change parameters of“taste”of different grades of Atractylodes macrocephala,and the sweetness of three grades of Atractylodes macrocephala was different.
