摘　　要：目的:了解有机氯农药残留及5种重金属(铜、砷、镉、汞、铅)在三七植物体中的残留特征。方法:于2013年4月选择云南省嵩明县白邑镇、寻甸县六哨乡3年生三七进行样品采集,采集三七植株60株及其根际土壤样品1 kg。对其各个部位及栽培土壤样品进行有机氯农药残留及5种重金属的检测。采用2010年版《中国药典》(一部)的农药残留量测定法测定有机氯农药残留,采用铅、镉、汞、砷、铜法测定5种重金属。结果:嵩明县白邑镇三七各部位均检出五氯硝基苯,其含量为根皮>须根≥剪口>筋条>茎叶;而寻甸县六哨乡三七仅根皮及须根中检出五氯硝基苯,其含量为根皮>须根。三七样品各部位均未检出汞,其他重金属含量均以须根中最高;土壤中砷、铅含量较高,而样品中砷、铅含量远低于土壤。结论:三七不同部位的农药、重金属的含量是不同的,须根部位农药、重金属含量相对较高。三七样品含有有机氯农药残留,主要为五氯硝基苯;三七对镉的蓄积能力较强。OBJECTIVE：To know the residual characteristics of organochlorine pesticides and 5 kinds of heavy metals（Cu,As,Cd,Hg and Pb） in Panax notoginseng. METHODS：P. notoginseng samples with 3 years were collected from Baiyi Town,Songming County and Liushao Township,Xundian County of Yunnan Province in Apr. 2013. 60 strains of P. notoginseng and 1 kg rhizosphere soil samples were also collected. The organochlorine pesticide residues and 5 kinds of heavy metals on its various parts and soil samples were detected. Pesticide residues determination method in Chinese Pharmacopoeia（2010 edition,volumeⅠ）was conducted to determine the organochlorine pesticides and 5 kinds of heavy metals（Cu,As,Cd,Hg and Pb）. RESULTS：There was pentachloronitrobenzene in different parts of P. notoginseng from Baiyi Town,Songming County,and the contents were root bark〉fibrous≥notches〉ribs〉leaves;there were pentachloronitrobenzene only in the root bark and fibrous of P. notoginseng from Liushao Township,Xundian County,and the contents were root barkfibrous. No Hg was detected in any part of P. notoginseng samples,and the other heavy metals were highest in root bark;As and Pb were relatively high in soil,the contents of As and Pb in samples were far lower than in soil. CONCLUSIONS：The contents of pesticide residues and heavy metals in different parts of P.notoginseng are different,and those in root bark are relatively high. P. notoginseng sample contains organochlorine pesticides,which is mainly pentachloronitrobenzene;P. notoginseng sample has relatively strong accumulation of Cd.
