Cytotoxicity of Captafol in Mammalian Cells

The cytotoxicity of captafol, a phthalimide-derived fungicide, was evaluated in IB-RS-2 cells. Captafol at 0. 12-1 .0μg/ml blocks the cell multiplication. This effect is concentrationdependent, only partially rcversible and the degree of inhibition increases with time. The synthesis of DNA and RNA is inhibited in parallel by increasing concentrations of the chemical

气相色谱法测定蔬菜中克菌丹、灭菌丹、敌菌丹残留量的研究

建立蔬菜中克菌丹、灭菌丹和敌菌丹三种农药同时测定的气相色谱检测方法。样品用丙酮提取,经正己烷液液萃取,弗罗里硅土和石墨化碳黑混合柱净化,以具有电子捕获检测器(ECD)的气相色谱(GC)仪测定。方法在0.01、0.05、0.1mg/kg三个添加水平时的三种农药的平均回收率为克菌丹71.6%～100.2%、灭菌丹78.6%～104.6%、敌菌丹70.2%～86.9%、相对标准偏差为克菌丹8.5%～12.9%、灭菌丹5.1%～11.2%、敌菌丹8.7%～13.6%、方法定量限为克菌丹0.005mg/kg、灭菌丹0.003mg/kg、敌菌丹0.01mg/kg。

气相色谱法测定马铃薯、番茄中克菌丹、灭菌丹、敌菌丹残留量的研究

建立了马铃薯和番茄中克菌丹、灭菌丹和敌菌丹三种农药同时测定的气相色谱检测方法。样品用丙酮提取，经正己烷液液萃取，弗罗里硅土柱净化，以具有电子捕获检测器（ECD）的气相色谱（Gc）仪测定。方法在0．01、0．05、0．25mg／kg三个添加水平时的三种农药的平均回收率在71．9％-116．36％之间，变异系数为3．74％-15．86％；方法定量限为克菌丹0．005mg／kg、灭菌丹0．003 mg／kg、敌菌丹0．01mg／kg。
