To explore the effect of the content of soil heavy metal elements on the fruit of L.Bararum,10 kinds of heavy metal elements in soil and fruits of Lycium barbarum L.from six main producing areas in China were measured and compared by the method of ICP-MS.The results showed that the contents of heavy metal elements in soil showed significant difference among six areas;The contents of Cd,Cr,As,Li,Ni,Co,Sr and Y were higher in Xinjiang,the contents of Pb and La were higher in Ningxia,and the contents of Pb and La were higher in Hebei.The contents of Pb,As,Ni in fruit of L.Bararumin six areas were not significant difference,and significant difference among other heavy metal elements.The contents of Cd and Sr infrait were higher in Ningxia,the contents of Cr infrait were higher in Inner Mongolia and Qinghai,the contents of Li infrait were higher in Gansu,and the contents of La,Co and Y infrait were higher in Hebei and Qinghai.The concentration of Cd in fruit was significantly positive correlated with Pb,La,and Li in soil;Sr in fruit was significantly positive correlated with Li and La in soil;the content of Co in fruit was positive correlated with Y and La in fruit.The soils of all producing areas were suitable for the cultivation of L.Bararumand the contents of heavy metal elements in fruits did not exceed the national standards of Chinese traditional medicine.
