目的获得玄参药材及饮片有机氯农药残留概貌,建立玄参有机氯农药残留的限量标准。方法采用快速气相色谱法检测全国范围内10个代表产地的玄参药材及7个产地(30批次)玄参饮片中21种有机氯农药残留量,考察99%置信区间,制定玄参有机氯农药残留的限量标准。结果玄参样品中21种有机氯农药残留量为0.000 1~0.077 7 μg/g,其中六六六、七氯、硫丹占农药残留总量的93%~96%,拟定了玄参中有机氯农药残留国家限量标准。结论玄参中有机氯农药残留主要为六六六、七氯、硫丹,制定的玄参有机氯农药残留限量标准为总有机氯≤0.700 μg/g。

Objective To obtain profile of residues of organochlorine pesticides in medicinal materials and decoction pieces of Scrophulariae Radix; To establish the limit standard for the residue of organochlorine pesticides. Methods Rapid gas chromatography was used to determine the residues of 21 organochlorine pesticides in medicinal materials of Scrophulariae Radix from ten producing areas of China and 30 batches of Scrophulariae Radix Decoction Pieces from seven producing areas. The 99% confidence interval was investigated, and the limit standard for...
