[Objective]The aim was to determine residues of organochlorine pesticides in geo-authentic crude drugs Ophiopogon japonicus from Sichuan Province, and judge the quality of 0. Japonicus, so as to provide experimental data for the establishment of quality standard. [Method] With 0. Japonicus from Santai County of Sichuan Province as material, the contents of BHC, DDT and PCNB were determined by gas chromatog-raphy. [ Result ] The contents of residues of organochlorine pesticides in O. Japonicus from Santai County were all under the standards. [Conclusion] It was proved the superiority of 0. Japonicus as Sichuan Province geo-authentic crude drug from residues of organochlorine pesticides, which was accordance with CAP standard and food standard.%[目的]测定四川道地药材—“川麦冬”中残留有机氯农药的含量,以评判川麦冬作为四川道地药材的质量情况,为川麦冬药材质量标准的制定提供了试验数据,也为三台县所产麦冬作为四川道地药材的用药质量提供了依据.[方法]以四川三台县所产川麦冬为材料,采用气相色谱法测定其总六六六(BHC)、总滴滴涕(DDT)和五氯硝基苯(PCNB)的含量.[结果]三台县所产川麦冬中残留有机氧农药含量均低于限量标准.[结论]从有机氯农药残留含量方面印证了川麦冬作为四川道地药材的优越性,符合国家中药材GAP标准和食品标准.
