Abstract

The contents of K, Ca, Mg, Cu, Fe, Zn and Mn in rose flower tea were determined by flame atomic absorption spectrometry (FAAS) in this study. And the extracting characteristics of these trace elements in different soaking time and times were analyzed. A logarithmic relation between infusing amount of trace elements and soaking time was observed while a negative exponential relation between infusing amount and soaking times was found. And the infusing amount of the trace elements in rose flower tea complied with the following order: K >; Mg >; Ca >; Fe >; Zn >; Cu >; Mn. The Optimum conditions for soaking were obtained with soaking time 10-20 min and soaking for 1-2 times.
