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.
质量保证一直是医药芳香族植物生产和利用中的一个重要问题。由于挥发性有机化合物(voc)的存在，大多数药用植物都具有芳香特性，可使用气相色谱和质谱分析。更现代的技术使用电子鼻以及*的数据处理算法。电子鼻(e-nose)是设计用来模拟生物系统中气味的仪器。电子鼻包含多种气体传感器，它们与气味分子相互作用，产生电子信号。然后，传感器响应被发送到一个计算机系统，该系统使用多变量数据分析方法根据样品顶部空间中的挥发性有机化合物来区分数据的差异。本文综述了电子鼻技术在评价药用植物产品质量和安全性方面的应用。同时也说明了这些系统的优点和局限性。
