Abstract:: The content of Fe,Mn,Zn and Cu in Ginkgo leaves were determined by microwave digestion-flame atomic absorption spectrometry.In this experiment,the content of four microelements including Fe,Mn,Zn and Cu（μg/g） was 3657,243,136,87 respectively in the sample collected from campus of Shaanxi University of Technology; 2831,207,102,94 respectively in Hantai;3950,305,193,180 respectively in Chenggu;1944,250,130,77 respectively in Nanzheng and 1944,270,121,84 respectively in Mianxian;the limit of determination was Fe 0015,Mn 0019,Zn 00062 and Cu 0006 μg/mL;the rate of recovery was 92%～110%.The content of four elements was Fe>Mn>Zn>Cu in the same samples, and the content was higher in Chenggu than others.
