| Abstract: | The content of eight trace elements in Winter - jujube was determined by flame atomic absorption spectrometry （FAAS）. The recovery ratio of the method was from 96. 7% to 102.8% in the standard addition analysis and the RSD was less than 3.06%. The method was simple and accurate, it provides a scientific basis to the exploitation and utilization of Winter - jujube. |
