摘　　要：目的:测定和分析贵州不同产地天麻药材中As、Hg、Pb、Cd、Cu含量和有机氯农药残留量,为其质量控制和临床安全用药提供理论依据。方法:选取贵州省不同地区21批次天麻药材采用石墨炉原子吸收法测定铅、镉的含量,采用火焰原子吸收法测定铜的含量,采用原子荧光光度法测定汞、砷含量,采用气相色谱法测定药材中六六六、滴滴涕等9种有机氯农药残留量。结果:有2批次样品Cu、Cd超标,Pb、As、Hg及有机氯农药残留均未超过国家标准有关规定,另19批次天麻药材所有指标均未超标。结论:黔产天麻重金属及有害元素和农药残留情况较理想,本实验所建立的检测方法准确、灵敏,为黔产天麻药材的质量控制标准提供了理论依据。Objective： To determine and analyze the contents of arsenic（ As）,hydrargyrum（ Hg）,lead（ Pb）,cadmium（ Cd）,copper（ Cu） and nine kinds of organochlorine pesticides in Gastrodia elata from different areas of Guizhou and to provide a theoretical basis for the quality control and clinical medication safety of Gastrodia elata. Methods： The contents of Pb and Cd in 21 batches of Gastrodia elata from different areas of Guizhou were determined by graphite furnace atomic absorption spectrometry. The content of Cu was determined by flame atomic absorption spectrometry and the contents of Hg and As were detected by atomic fluorescence spectrometry. The concentrations of benzene hexachloride residue,DDT residue and other organochlorine pesticide residue were determined by capillary gas chromatography. Results： The contents of Cu,Cd in 2 batches of samples exceeded the standard,while contents of Pb,As,Hg and organochlorine pesticide residue in these 2 batches of samples were below the standard. Besides,in the other 19 batches of samples,all contents of heavy metal and organochlorine pesticide residue were below the standard. Conclusion： The heavy metals and organochlorine pesticide residue of Gastrodia elata from different areas of Guizhou province are relatively under control. The established methods are reliable and sensitive and in turn form a basis for the quality control of Gastrodia elata.
