Theelements concentrations in different parts of buckwheat and the commercialproducts of it were analysed by experimental and chemometric approaches. Theresults indicated that the essential and toxic elements concentrations weresignificantly different in various parts of the buckwheat, with the seedsrevealing the lowest concentrations. The elemental patterns were notsignificantly different between Fagopyrum tataricum (L.) Gaertn and F.esculentum Moench. Abundant essential elements were found in the commercialbuckwheat tea. The detection of heavy metals manifested the potential toxicityof buckwheat.
