Objective Through the determination and evaluation of the heavy metals and harmful elements in the medicinal ma-terials of Xianmao(Curculigo orchioides)from Yunnan,Guizhou and Sichuan provinces,it provides scientific basis for the devel-opment of the quality standards of heavy metals and harmful elements in the medicinal materials of Xianmao(Curculigo or-chioides).Method The samples were pretreated by microwave digestion,and the heavy metals and harmful elements in the sam-ples from various places of origin were detected and analyzed by inductively coupled plasma mass spectrometry(ICP-MS).Re-sults There were certain differences in the contents of heavy metals and harmful elements in samples from different places of ori-gin.Taking the Green Industry Standard for the Import and Export of Medicinal Plants and Preparations(2004)as a reference,the contents of arsenic,lead,mercury and copper met the standard,while the contents of cadmium in seven places of origin were high-er than 0.3 mg/kg.Conclusion The detection method of heavy metals and harmful elements in the medicinal materials of Xian-mao(Curculigo orchioides)established in the experiment has the advantages of being fast,simple and accurate.It can not only be used for the quality evaluation of the medicinal materials of Xianmao(Curculigo orchioides),but also provide a reference for the determination and evaluation of the contents of heavy metals and harmful elements in other kinds of Chinese medicinal materials.
