Abstract

Using to determine and analysis the trace element content in jujubes in order to develop the medicinal and edible value of different jujube.Microwave digestion-atomic absorption spectrometry.The content of six kinds of trace element in jujube are bellow Fe: 21.01 mg/kg-31.09 mg/kg,Ca: 607.40 mg/kg-787.80 mg/kg,Cu: 1.97 mg/kg-3.58 mg/kg,Zn: 6.46 mg/kg-14.91mg/kg,Mn: 2.64 mg/kg-3.67mg/kg,Mg: 358.60 mg/kg-431.40 mg/kg.The trace element is plentiful in jujube,specially Ca,Mg,Fe.
