摘      要：Objective:Authentication is vital to the reduction of the misuse of Panax species due to their extensive array of uses and similarities between ***,the current authentication approach is time-consuming,laborious,and *** aim of this study is to discriminate the botanical origins of five species in Panax genus by a rapid and simple ***:Here,an electronic tongue(E-tongue)was applied to discriminate the botanical origins of five species of Panax,i.e.,Panax quinquefolius,Panax japonicus,*** ***,Panax zingiberensis,and Panax notoginseng(representative high-,middle-,and low-latitude plants),and the four geographical origins of *** and *** *** *** preprocessing methods,including principal component analysis(PCA),hierarchical cluster analysis(HCA),and linear discriminant analysis(LDA),were ***:Three models can discriminate five species of Panax genus and four plants of *** and *** *** from different geographical *** was superior to PCA and HCA in terms of satisfactory ***:The findings confirmed the potential of the E-tongue for performing rapid,simple,and cost-effective discrimination via LDA.
