| Abstract: | Longan were ashed by drying-methed and the residues were dissolved by HNO_3.Ten trace elements including copper, zinc, iron, manganese, cobalt, mickel, calcium, magnesium, cadmium and lead in the solution were determined by flame atomic absorption sepectrophotometry. The results obtained show that longan contains higher amount of Ca, Mg, Fe and Zn than other elements. |
