Distribution of Inorganic Elements in Jeju Green Tea

Contents of inorganic elements in green tea produced in Jeju-do were determined by ICP-MS. Inorganic elements in Jeju green tea were within the range of K 27,362- 30,112 mg/kg, Ca 2,430- 2,919 mg/kg, Mg 1,873- 2,261 mg/kg, Mn 355 .85- 548.68 mg/kg， Fe 156.00- 165.47 mg/kg, Zn 54.69- 95 .94 mg/kg, B 27. 62- 33.64 mg/kg, Cu 9. 15- 13.00 mg/mg, Na 3 15.33- 370.69 mg/g， AI 289.63- 333.60 mg/kg, Si 53.98- 68.39 mg/g， Ni 19.49- 25.55 mg/kg， Cr 1 6.14- 1 7 .49mg/kg， Sr 4.1 8- 6.69 mg/kg, Co 1.49- 2.1 6 mg/kg， V 1.59- 1.94 mg/kg, and Se 0.06- 0.27 mg/kg. The amounts of K, Ca, Mg, Co, Cr, and Na were higher than in china green tea while the amounts of Fe, Zn, B, Na, and Ni were higher than in japan green tea. However, the amounts of Mn, AI, Sr, Se, and AI were lower than in china green tea, with Ca content lower than in japan green tea. In relation to Jeju-do, the contents of Mg, Cr, and Se were highest in the eastern area, the contents of Ca, Mo, Ni, V, Sr, and Na were highest in the western area, and the contents of K, Zn, B, Cu, Co, AI, and Si were highest in the southern area
