The contents of trace elements Ca, Mg, Fe, Mn, Cu and Zn in tea leaves of Mengshan which plucked in different seasons were determined by flame atomic absorption spectrometry (FAAS). The concentration and dissolved rates of six trace elements in their influsiong were calculated. The correlations of trace elements were analyzed using SPSS18.0 analysis software. The result showed that there were abundant trace elements in tea leaves of Mengshan, the contents order is Ca>Mg>Fe>Mn>Zn>Cu. There were positive correlation between Fe and Mn, Ca and Zn. On the contrary, Ca has a negative correlation with Zn. The seasonal dynamics of these elements had obvious regularity in tea leaves. The dissolved rates of various elements were correlated to the form of elements in tea, however, there is no significant relationship between dissolved rates and the plucking seasons.
