To study eleven organophosphorus insecticides residuals in four kinds of Chinese crude drugs.
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).
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.
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.
研究四种中药材中11种有机磷杀虫剂残留量。
用二氯甲烷提取有机磷杀虫剂，并用硅藻土545 - 活性炭混合物进行净化。提取物采用配有火焰光度检测器（FPD）的气相色谱仪进行分析。
对加标中药材的分析表明，在三个不同水平下平均回收率为77.5% - 112.3%，相对标准偏差低于10%（n = 4）。在白术和菊花样品中发现了痕量有机磷农药残留。
建立了白术、郁金、浙贝母和菊花中多残留量的测定方法。为中药材中有机磷农药的风险评估提供了一种方法。
