Origin Identification of Panax notoginseng Based on Fusion Technology of Electronic Nose and Tongue
Objective To develop a rapid identification method for Panax notoginseng(P.notoginseng)from different origins based on electronic nose and tongue technology.Methods Electronic nose and electronic tongue were used to evaluate the odor and taste characteristics of 11 batches of P.notoginseng samples from different origins.Based on the single sensory information and the fused sensory information,principal component analysis(PCA),partial least squares discriminant analysis(PLS-DA)and orthogonal partial least squares discriminant analysis(OPLS-DA)were used to establish the discriminant model of P.notoginseng in different producing regions.Results The discrimination model demonstrates that multi-sensors data fusion presented obvious superiority to the independent electronic nose and tongue signals,and based on the fusion of sensory information,the rapid identification of P.notoginseng from traditional and emerging producing areas could be realized.Conclusion The technology of electronic nose and tongue can be used for the identification ofP.notoginseng from different origins,and the effect of the model after intelligent sensory data fusion is better than that of using electronic nose or tongue alone,which provides reference for the identification of the origin of Chinese medicinal materials.
