摘　　要：为了对白术药材的气味信号值与内酯类成分含量进行相关性分析,为白术药材品质的快速评价提供依据。利用电子鼻技术对白术药材粉末进行气味检测,高效液相色谱法测定白术药材中白术内酯Ⅰ、Ⅱ、Ⅲ含量,利用统计软件对电子鼻信号值与三种化学成分含量进行相关性分析。结果显示,电子鼻传感器W3S与白术内酯Ⅰ的含量具有显著相关性,传感器W5S与白术内酯Ⅱ的含量显著相关。因此,通过电子鼻W5S与W3S传感器信号值可快速判定白术药材中白术内酯Ⅱ与白术内酯Ⅰ的含量,为白术性状鉴别的标准化与现代化提供依据,电子鼻技术可作为快速鉴别白术品质的新方法加以开发利用。Objective: To analyze the correlation between the odor signal value and lactone content of Atractylodes macrocephala by electronic nose technology, so as to provide the basis for the rapid evaluation of the quality of Atractylodes macrocephala. Methods: The odor of Baizhu powder was detected by electronic nose technology, and the contents of Baizhu lactone Ⅰ, Ⅱ and Ⅲ were determined by HPLC. The correlation between the signal value of electronic nose and the contents of three chemical components was analyzed by statistical software. Results: There was a significant correlation between w3 s and atractylode Ⅰ, w5 s and atractylode Ⅱ. Conclusion: The signal value of w5 s and w3 s sensors can be used to determine the content of atractylode Ⅱ and atractylode Ⅰ in Atractylodes macrocephala, and provide basis for standardization and modernization of Atractylodes macrocephala character identification. The electronic nose technology can be used as a new method to identify the quality of Atractylodes macrocephala.
