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。

Abstract: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 carbon. 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 multi-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.
