Copper in glycyrrhiza was determinated by Graphite Furnace Atomic Absorption Spectrometry（GFAAS）.Several conditions of GFAAS were selected.The results showed that the linear range of calibration curve was 20-100 ng.mL-1,the average recovery rate with standard addition mode was 99%,and the relative-standard deviations for the determination were no more than 1.66%.The method is simple,reliable and could be used for determination of practical samples.
