A total of 92 samples from three countries

ie.the United States

Canada and PR.China were determined by inductively coupled plasma mass spectrometry(ICP-MS) and inductively coupled plasma(ICP)-optical emission spectroscopy(OES).A regional discrimination model was set up using the mineral element content combined with chemometrics of Principal component analysis(PCA) and Partial least squares discriminant analysis(PLS-DA).Results showed that the PCA and PLS-DA multivariate statistical models could be used to distinguish the cherry samples from these three countries.Cherries from the United States

Canada and China appeared a certain clustering effect

but Canadian cherries exhibited a certain intersection with American cherries.The PLS-DA origin traceability model for cherry samples showed that 20 elements such as Pr

Be and Zn were the main significant elemental variables.According to the distribution of these 20 elements

the traceability identification model for cherries could be constructed.The identification rates of the PLS-DA origin traceability model for the three source cherry samples was 50% from the US

83.3% from Canada and 83.3% from China.
