| Abstract: | Adopting HNO3-HClO4 (4:1) digestion samples, we determined the contents of trace elements Cu and Mn in leaves and stems of Chinese cabbage by using the flame atomic absorption spectrometry (FAAS) method, to study the food and industrial application value of Chinese cabbage. The results showed that, both Cu and Mn contents had significant difference in leaves and stems of Chinese cabbage, and the contents of Mn were higher than Cu in leaves and stems, in addition, the contents of the two trace elements were higher in leaves than those in stems. |
