广西部分钩藤药材重金属和有机氯农药残留量

Analysis of heavy metals and organochlorine pesticide residues in ramulus uncaria cum uncis in Guangxi

目的:通过对广西部分钩藤药材重金属和有机氯农药残留量分析,对其安全性进行评价。方法:采用原子吸收分光光度法和气相色谱法分别测定9种钩藤药材17批样品的铅、镉、砷、汞、铜和六六六、滴滴涕、五氯硝基苯含量。结果:14批样品的5种重金属元素含量全部合格,3批样品的镉超标,全部样品的有机氯农药残留量合格。结论:全部样品有机氯类农药残留量和大部分样品重金属含量均在安全范围内,但有部分样品存在镉超标的安全隐患。

Objective：To investigate the heavy metals and organochlorine pesticide residues in Ramulus Uncaria Cum Uncis in Guangxi,and to evaluate their safety.Methods： The heavy metals（Pb,Cd,As,Hg,Cu） and organochlorine pesticide residues（BHC,PCNB,DDT）in 17 samples of 9 variaties of Ramulus Uncaria Cum Uncis in Guangxi were determined by AAS and GC,respectively.Results： Five heavy metals in 14 samples were all qualified;but Cd contents in 3 samples exceeded the standard limit;and organochlorine pesticide residues in all samples were all qualified.Conclusion： The organochlorine pesticide residues in all samples and heavy metals in most samples were in the safety range,but Cd in some samples was in the risk of exceeding the standards.
