摘要
目的：调查研究白术、温郁金、贝母、杭白菊中11种有机磷农药残留量的污染情况。方法：样品用二氯甲烷提取,并经活性炭和助滤剂-545混合物柱色谱净化,用气相色谱配FPD进行测定。结果：3档农药的添加平均回收率在77.5%~112.3%,RSD均小于10%（n=4）。在白术、杭白菊等中药材中检测出痕量有机磷农药的残留。结论：本实验选取白术（根）、温郁金（根茎）、贝母（鳞茎）、杭白菊（花）中药材进行有机磷农药的多残留检测,为评价我国中药材中的有机磷农药污染状况提供科学依据。
Objective： To study eleven organophosphorus insecticides residuals in four kinds of Chinese crude drugs. Method： The organophosphorus insecticides were extracted with dichloromethane and cleaned-up with a mixture of Celite 545-activated carben. The extracts were analyzed by gas chromatography equipped with a flame photometric detector （FPD）. Result： Analysis of fortified Chinese crude drug showed that the average recoveries ranged from 77. 5%-112. 3% at three different levels, the RSDs were below 10% （n = 4）. Trace organophosphorous pesticide residues were found in samples of Rhizoma Atractylodis Macrocephalae and Flos Chrysanthemi. Conclusion： A method was established for determination muhi-residues in Rhizma Atractylodis Macrocephalae, Radix Curcumae, Bulbus Fritillariae Thunbergii and Flos Chrysanthemi. It provides a method for the risk assessment of organophosphorous pesticide in Chinese crude drugs.
