Geographical discrimination of Cyclocarya paliurus tea for origin traceability based on multielement analysis by ICP-OES and chemometrics multivariate.

ABSTRACT:

Objective

This paper focused on the geographical discrimination of Cyclocarya paliurus tea for origin traceability based on multielement analysis by ICP-OES and chemometrics multivariate.

Methods

In this study, eleven trace element concentrations were determined by ICP-OES and processed by multivariate statistical analysis.

Results

Based on ANOVA, the mean concentrations of 10 elements except Co differed significantly among six origins. Pearson's correlation analysis showed that 11 pairs of elements have a positive significant correlation and 12 pairs have a negative significant correlation. The geographical origins were effectively differentiated using the eleven elements combined with PCA. And the S-LDA model offered a 100% differentiation rate.
