Objective: Determine trace elements in root r stem and fruit of Fructus Rosae Laeriga-tae.Methods: We handle samples with acerbic (HNO3-H2O2) micware-digestion, and thendetermine trace elements of its different parts by atomic absorption spectrometry, and use SPSSstatistical method to deal with data of result.Results: In fruit got by ourselvea r fruit on sell r stem r root, content of Cu is respective 5.195±0.111, 3.313±0.401,1.713±0.156, 1.857±0.191, content of Cu is respective Zn 422.584q-15.389, 339.541±6.055, 204.541 ±5.377, 432.209±4.874;content of Ca is respective 2538.708+50.793, 3137.625±81.331, 2596.875±68.337, 1554.541+42.743; content of Mg is respective1186.958±86.479, 2452.087±51.908,429.041±19.740, 663.750±23.867; content of Mn is respective 134.929± 12.522, 148.688±1.833, 18.604±0.2855, 14.304±0.884; content of Cr is respective 3.097±0.167, 2.401±0.148,1.672±0.079, 3.561±0.079; content of Ni is respective 1.878±0.073, 2.142±0.061, 0.896±0.068, 0.488±0.025; content of Fe is respective 1396.666±18.833,950.250±14.414, 60.900±0.651, 70.221±1.328; content of Co is re-spective 0.304±-0.038, 0.525±0.032, 0..758±0.068, 0.662±0.057, Ca, Fe, Cu, Cr, Ni, Mn, Mg, Co all are differential in comparison between fruit and root ,stem.So are Ca, Cr, Ni, Mg, Zn between root and stem.
