摘要(Abstract):

[Objective] To measure the content of iron, calcium, manganese, chromium, nickel and copper in Allium macrostemon. [Method] An investigation about the effects of wet digestion and dry ashing method on the determination results were performed on raw material A.macrostemon, sampled from Xishan Mountain in Mudanjiang City. Atomic absorption spectrometry (AAS) was adopted to determine the content of iron (Fe), calcium (Ca), manganese (Mn), chromium (Cr), nickel (Ni) and copper (Cu) in A. macrostemon. Precision test and recovery test were made. [Result] A. macrostemon contained many kinds of nutrient elements that were essential to human body, among which the content of calcium was the highest at 1.2407mg/g, of iron was the middle, of manganese and chromium was the lowest. Besides, nickel and copper could not be detected. [Conclusion] This method has the advantages of time-saving, labor-saving, high sensitivity, fast speed of analysis, and high accuracy, so that it is fit for the analysis of constant and trace elements in A.macrostemon.
