DETERMINATION OF EIGHT METAL ELEMENTS IN THREE KINDS CHRYSANTHEMUM TEA BY FAAS

Eight metal elements in three kinds chrysanthemum tea were determined with wet digestion(HNO3:HClO4=5:1) by flame atomic absorption spectrometry.The results showed that there were rich contents of metal elements in three kinds chrysanthemum tea,the value of exploiture and utilization is every high,however,the contents had significant difference among individuals.The content of metal elements,such as K,Na,Ca,Mg,Fe,Cu,Zn,were higher in wild chrysanthemum,they were 22.207 9 mg/g,169.981 0 μg/g,17.118 5 mg/g,3.341 4 mg/g,149.465 0 μg/g,16.110 4 μg/g,39.647 9 μg/g respectively;while higher content of Mn was 160.702 8 μg/g in Huangshan chrysanthemum tea,and lower content of eight metal element in white chrysanthemum tea.The results will provide certain theory bases for peoples' reasonable choice of chrysanthemum tea.
