| Abstract: | Metal elements in rose tea were determined with wet digestion V(HNO_3)+V(HClO_4)=5+1 by flame atomic absorption spectrometry.The results showed that the content of metal elements,such as K,Ca,Na,Mg,Fe,Mn,Cu,Zn was rich in rose tea,they was 11.655 9 mg/g,6.564 2 mg/g,23.314 7 μg/g,2.053 3 mg/g,25.871 1 μg/g,20.589 7 μg/g,7.910 7 μg/g,23.249 3 μg/g respectively,and the elemental proportion are beneficial to human,then the value of nutrition and health is very high.The results will provide a certain theory bases for peoples, reasonable choice of rose tea. |
