目的:测定本溪地产的林下山参、生晒参、红参、池底参中有机氯类农药残留量并进行比较。方法:样品用石油醚提取,以硫酸磺化,采用DB-1701毛细管柱(30m×0.32mm×0.25μm)及电子捕获检测器(63Ni-ECD),外标法计算含量。结果:这种方法可以有效区别不同种类人参中有机氯类农药残留量。结论:林下山参、生晒参、红参、池底参中有机氯类农药残留量存在差异。
OBJECTIVE: To determine the residual amount of organochlorine pesticides in Linxia ginseng, raw ginseng, red ginseng and ginseng ginseng in Benxi real estate and to compare them. Methods: The sample was extracted with petroleum ether and sulfonated with sulfuric acid. The content was calculated by external standard method using DB-1701 capillary column (30m × 0.32mm × 0.25μm) and electron capture detector (63Ni-ECD). Results: This method can effectively distinguish different types of ginseng residues of organochlorine pesticides. Conclusion: There are differences in organochlorine pesticide residues in understory ginseng, raw ginseng, red ginseng and ginseng.
