Abstract: The contents of Mn, Zn and Cu, three essential trace elements for human body, in Laminaria japonica, Auricularia auricula (L.ex Hook.) Underwood, Porphyra, Cucurbita pepo L., Spinacia oleracea L. and Coriandrum sativum were determined by atomic absorption spectrophotometry. Vegetable samples were processed by wet digestion. The results showed that among the six vegetables, Mn had the highest content in A. auricula (26.60 μg/g) and the lowest content in C. pepo (1.22 μg/g); Zn had the highest content in Porphyra (38.07 μg/g) and the lowest content in L. japonica (10.32 μg/g); and Cu had the highest content in Porphyra (10.35 μg/g) and the lowest content in S. oleracea (0.61 μg/g). Each determination was repeated five times. The value of RSD was less than 10%, indicating high accuracy.
