Quality assurance has always been an important issue in the production and utilization of medicinaland aromatic plants. Most medicinal plants have aromatic characteristics due to the presence of VolatileOrganic Compounds (VOCs) that can be analyzed using gas chromatography and mass spectroscopy. Moremodern techniques use sensors along with signal processing and advanced data processing algorithms.Electronic noses (e-noses), are instruments designed to mimic the sense of smell found in biologicalsystems. E-noses contain numerous types of gas sensors that interact with odor molecules to produceelectronic signals. Then, the sensor responses are sent to a computer system that uses m*riate dataanalysis methods to distinguish differences in the data based on the VOCs in the sample headspace. Thispaper provides a review of the applications of e-nose technologies for assessing the quality and safety ofcommercially-available medicinal plant products. Advantages and limitations of these systems are alsocovered.
質量保證一直是醫藥芳香族植物生產和利用中的一個重要問題。由于揮發性有機化合物(VOC)的存在，大多數藥用植物都具有芳香特性，可使用氣相色譜和質譜分析。更現代的技術使用電子鼻以及*的數據處理算法。電子鼻(e-nose)是設計用來模擬生物系統中氣味的儀器。電子鼻包含多種氣體傳感器，它們與氣味分子相互作用，產生電子信號。然后，傳感器響應被發送到一個計算機系統，該系統使用多變量數據分析方法根據樣品頂部空間中的揮發性有機化合物來區分數據的差異。本文綜述了電子鼻技術在評價藥用植物產品質量和安全性方面的應用。同時也說明了這些系統的優點和局限性。
