Abstract
An analytical method for the determination of Patulin in tomatoes, pears, apples, cucumbers and plums is described. The determination limit of the method is 40 mug Patulin/kg. With additions between 100-500 mug Patulin/kg the recovery rates lie between 86--95%. After a pre-purification of the crude extract by column chromatography and liquid-liquid extraction the Patulin is determined thin-layer chromatographically by reflectance measurement at 273 nm.
摘要
本文描述了一种测定番茄、梨、苹果、黄瓜和李子中展青霉素的分析方法。该方法的测定限为40微克展青霉素/千克。添加量在100 - 500微克展青霉素/千克之间时，回收率在86% - 95%之间。粗提物经柱色谱和液液萃取预纯化后，通过在273nm处的反射率测量用薄层色谱法测定展青霉素。
