Abstract

Abstract: The sample was digested with HNO₃-HCIO₄ mixed acid, and the contents of Fe, Mg, Ca, Mn, Zn and Cu in mulberry and mulberry leaves in Lintong county of Shaanxi province were determined by flame atomic absorption spectrophotometry. Meanwhile, the precision and standard addition recovery tests were conducted, and the contents of mineral elements in mulberry and mulberry leaves were compared and analyzed. The experimental results show that both mulberry and mulberry leaves contain rich trace elements, and the order of mineral element content in mulberry and mulberry leaves are Ca>Mg>Fe>Mn>Zn>Cu, in order to provide theoretical basis for deep processing, nutrition, medical research and development and utilization of mulberry and mulberry leaves.

Key words: flame atomic absorption spectrometry, mulberry, mulberry leaves, mineral element
