Abstract:
This study was aimed to distinguish Leonurus japonicus samples produced from different regions and growth environments in Sichuan by electronic nose. The sensor response value of odors of Leonurus japonicus sam-ples were obtained through electronic nose. Principal component analysis (PCA) and discriminant factor analysis (DFA) were used to combine the optimum feature parameters. The results showed that the PCA distinguish index was 82, and the DFA comprehensive classification rate was 97.96% among samples from different regions. The PCA distin-guish index was 84, and the DFA comprehensive classification rate was 100% among samples from different growth environments. The distinguishment and differentiation were effective. It was concluded that electronic nose can be ap-plied to identify the origin and growth environment of Leonurus japonicus from Sichuan to provided reference for odor differentiation.
