Abstract: A method for geographical origin discrimination of Panax notoginseng was established to provide technical support for the protection of geographical indication products and for tracing the geographical origin of agricultural products. Sixty samples of spring Panax notoginseng were collected, inductively coupled plasma mass spectrometry was used to determine the contents of 44 mineral elements in the main root of spring Panax notoginseng, and analysis of variance, principal component analysis and discriminant analysis were carried out to develop and validate the discriminant model. The results showed that, the contents of 13 mineral elements in samples were different among four producing areas. The content and composition of mineral elements in the root of spring Panax notoginseng had their own geographical fingerprint characteristics in different sections. Through the stepwise discriminant analysis, K, Ca, Mg, Mn, Mo, Co and Sc were selected for the discriminant model from different elements. The overall correct discrimination rates for original spring Panax notoginseng samples from different geographical origins in back substitution and cross validation tests were 80.0% and 71.7%, respectively. The mineral elements fingerprint analysis combined with chemometrics could be used to distinguish the geographical origin of Panax notoginseng from different producing areas.

Key words: spring Panax notoginseng (Burk.) F.H.Chen, mineral elements, fingerprint spectrum, chemometrics, discriminations of the geographical origin
