[Objective] Flame atomic absorption spectrometry was used to determine the levels of elements content in Asparagus officinalis L.,which could provide references for the rational utilization and development of A.officinalis L.[Method] A.officinalis L.samples were digested using nitric acid and hydrogen peroxide as solvents in high-pressure closed-vessel.LaCl3 and CsCl were used as releasing agent to eliminate the chemical interference to calcium,magnesium and potassium determination.[Result] The rate of recovery varied from 91.2% to 112.3%,and the relatively standard deviation was from 1.43% to 2.17%.The copper,iron,zinc and calcium contents of A.officinalis L.cans were higher than those before processing,but their potassium and magnesium content were lower than those before processing.The copper,iron,zinc,calcium,magnesium and potassium contents of green A.officinalis L.were higher than those contained in white Asparagus offcinalis and utilization.

[Result] The rate of recovery varied from 91.2% to 112.3% , and the relatively standard deviation was from 1.43% to 2.17%. The copper, iron, zinc and calcium contents of A. officinalis L.cans were higher than those before processing, but their potassium and magnesium content were lower than those before processing. The copper, iron, zinc, calcium, magnesium and potassium contents of green A. officinalis L. were higher than those contained in white Asparagus offcinalis and utilization.
