| Abstract: | Green tea, a traditional healthy drink, has various necessary nutrients. A study was carried out on the contents of mineral elements such as Ni, Ba, Fe, Mn, Cr, Mg, Ca, Cu and Al in two grades of three green tea varieties by ICP-AES. The difference in contents of mineral elements between green teas was studied. The results indicated that there are different contents of mineral elements among varieties and grades of green tea. A basis for consumption, varieties identification and grades judgment was provided by the study. |
