目的:探讨用电子鼻检测量化中西药物的四气五味的方法与可行性。方法:用电子鼻检测13味清热中药和2种西药(氧化苦参碱、靛玉红),观察各药主成分分析(PCA)和雷达图的相似性和差异性,以此作为检测量化依据。结果:本研究所检测的清热药之间PCA、雷达图有较高的相似性,与它们相近气味相应。结论:电子鼻可以用于检测量化中西药的四气五味。
Objective: To explore the method and feasibility of using electron nose to quantify the four gas and five flavors of Chinese and Western medicines. Methods: Thirteen Chinese herbs and two western medicines (oxymatrine and indirubin) were detected by electronic nose. The similarity and difference between principal component analysis (PCA) and radar chart of each drug were observed and used as the basis for detection . Results: There was a high similarity between the PCA and radar images of the heat-clearing drugs detected in this study, which corresponded with their similar odors. Conclusion: Electronic nose can be used to detect four gas and five flavors of Chinese and Western medicine.
