摘　　要：目的:利用电子鼻方法准确、快速鉴别不同产地的豨莶草。方法:通过正交试验对不同产地豨莶草的称样量、孵化时间、粉碎粒度、孵化温度等因素进行筛选,确定不同产地豨莶草电子鼻检测的最佳条件;再通过主成分分析(PCA)多元统计学方法对特征数据进行分析。结果:建立了不同产地豨莶草的电子鼻检测方法及PCA识别模式。结论:该方法准确、快速,可为中药材的快速鉴别及气味的科学化、标准化研究提供新的思路。OBJECTIVE： To distinguish Herba Siegesbeckiae from different producing areas accurately and rapidly by electron- ic nose technology. METHODS ： The optimum conditions of electronic nose for Herba Siegesbeckiae from different producing areas was determined by orthogonal test, using sample size, incubation time, fineness of pulverization, incubation temperature as fac- tors. The characteristic data were analyzed by PCA multivariate statistical method. RESULTS ： The detection methods of electronic nose and PCA identification mode were established for the identification of Herba Siegesbeckiae from different producing areas. CONCLUSIONS： The method is accurate and rapid, and can provide new ideas for the rapid identification, scientific and standard odor study.
