Abstract

A method for the multielemental determination of metals and nonmetals in goji berries (Lycium barbarum L.) by axially and radially viewed inductively coupled plasma-optical emission spectrometry (ICP-OES) is presented. The accuracy of the entire proposed method was confirmed by three certified reference material analyses, and the certified values showed a good agreement at a 95% confidence limit (Student's Rest).
