Abstract:
Objective To establish odor fingerprint determination method of Aurantii Fructus from different growing areas based on bionic olfaction technology, and provide the reference for the quality control of Aurantii Fructus. Methods The bionic olfactory system (electronic nose, PEN3) was used to measure the odor of Aurantii Fructus from different growing areas; The LDA (Linear discriminant analysis) method was used to determine its odor fingerprint, and the simulation for identification was realized based on MATLAB 2013. Results Although these odor fingerprints of Aurantii Fructus from different growing areas were similar, there were significant differences in peaks' value from each other. The established odor fingerprints can achieve the 96% identification accuracy between known and unknown samples. Conclusion The method is simple, accurate and repeatable, which can be used for quality control of Aurantii Fructus from different growing areas.
