目的了解贵州中药材GAP基地药材中有机氯农药残留状况。方法在贵州11个主要GAP药材基地采集中药材样品155个,采用气相色谱法检测9种有机氯农药含量。结果155个样品中有39个样品检出农药,检出率25.16%。其中六六六(BHC)、滴滴涕(DDT)、五氯硝基苯(PCNB)的检出率分别为15.48%、2.28%和5.81%。25种药材农药总残留量大小为:根系类>全草类>树皮类>茎叶类>花果类。参照《药用植物及制剂进出口绿色行业标准》,有11个样品超标,超标率为7.09%,超标的为根系类药材。结论贵州中药材GAP基地大部分药材中有机氯农药残留量低于《药用植物及制剂进出口绿色行业标准》。
Objective To understand the status of organochlorine pesticide residues in medicinal materials of GAP base in Guizhou traditional Chinese medicine. Methods A total of 155 samples of Chinese medicinal materials were collected from 11 major GAP medicinal bases in Guizhou Province. The contents of 9 organochlorine pesticides were determined by gas chromatography. Results Among 155 samples, 39 samples were detected pesticides, the detection rate was 25.16%. The detection rates of BHC, DDT and PCNB were 15.48%, 2.28% and 5.81% respectively. The total residues of pesticides in 25 medicinal plants were: root system> whole plant> bark> stems and leaves> flower and fruit. With reference to “green industry standards for the import and export of medicinal plants and preparations”, 11 samples exceeded the standard, exceeding the standard rate of 7.09%, exceeding the standard for root medicines. Conclusion The residues of organochlorine pesticides in most medicinal materials of GAP base of traditional Chinese medicine in Guizhou are lower than the “Green Industry Standard for Import and Export of Medicinal Plants and Preparations”.
