摘要: 目的:基于超快速气相电子鼻技术建立一种快速鉴别木香与川木香的方法。方法:收集市场上不同来源的木香与川木香样品,基于Heracles Ⅱ超快速气相电子鼻探索建立合适的气味分析方法,结合Kovats保留指数及Arochembase数据库对木香和川木香的气味化合物进行分析研究;针对采集的气味指纹信息,建立主成分分析(PCA)、判别因子分析(DFA)、软独立建模分析(SIMCA)和统计质量控制分析(SQCA)模型,对其气味信息进行数据处理和分析。结果:通过对比气味指纹信息发现木香与川木香存在较大差异,建立的PCA、DFA、SIMCA、SQCA模型均能实现对木香与川木香的快速识别。结论:该方法简单、快速、准确,为快速无损鉴别木香和川木香提供了新技术和新依据。

Abstract: Objective: To establish a rapid identification method for Aucklandia lappa and Vladimiriae souliei by ultra-fast gas-phase electronic nose technology. Methods: Collect samples of Aucklandia lappa and Vladimiriae souliei from different sources, explore and establish suitable odor analysis methods based on Heracles Ⅱ ultra-fast gas-phase electronic nose, and analyze the odor compounds of Aucklandia lappa and Vladimiriae souliei using Kovats retention index and the Arochembase database; establish principal component analysis(PCA), discriminant factor analysis(DFA), soft independent modeling of class analysis(SIMCA) and statistical quality control analysis(SQCA) models for the collected odor fingerprint information, and analyze the odor information. Results: By comparing the odor fingerprint information, it was found that there are significant differences between Aucklandia lappa and Vladimiriae souliei. The established PCA, DFA, SIMCA and SQCA models can all achieve rapid identification of Aucklandia lappa and Vladimiriae souliei. Conclusion: This method is simple, fast, and accurate, providing new technology and basis for the rapid and non-destructive identification of Aucklandia lappa and Vladimiriae souliei.
