【 摘 要 】

Artemisia annuaandPyrus pashiaare used to relieve and treat many human diseases due to their low side effects. They are rich source of biologically important elements, which may play an important role in the observed therapeutic uses of these plants. It is important to have a good quality of medicinal plants in order to protect consumers from contamination. Therefore, the aim of the present study was to carry out a comparative evaluation of heavy and essential metals contents inA. annuaandP. pashia. The heavy and essential metals (As, Cd, Zn, Ni, Pb and Hg) contents ranged between1.82±0.54 - 1.86±0.22, 0.30±0.07 - 0.36±0.15, 18.00±3.32- 27.00±2.53, 1.22±0.44 - 3.02±0.55, 1.24±0.54 - 1.84±0.42 and 1.60±0.84 - 1.92±0.35 mg/kg respectively inA. annua, while forP. pashiathese varies from 2.65±1.83-2.81±0.25, 0.02±0.06-0.05±0.25, 13.50±3.13 - 25.20±1.18, 0.21±0.82 - 2.42±0.24, 0.38±0.03 - 1.05±0.08 and 1.48±0.78 -1.82±0.46 mg/kg respectively.The highestCd, Zn, Ni, Pb and Hgcontent was detected inroots ofA. annua, while highest concentration of As was found inleaves ofP. pashia. The contents were well within the permissible limits therefore, it can be used in the cure system.
