The present paper gives a survey of the chemical, physical and biological properties of the mycotoxin sterigmatocystin. It must be regarded as toxic to warm-blooded animals and as cancerogenic. It is likely to occur in foods; therefore, its analytical detection is necessary. With reference to known confirmatory reactions, a method is described for the semi-quantitative determination of sterigmatocystin in fruit and vegetables. This method permits to detect 20 microgram/kg of food by means of thin-layer chromatography, after column-chromatographic purification on silica gel. The identity is confirmed by derivatization to the semi-acetal by treatment with trifluoro-acetic anhydride. The method is suited especially for the routine control of foods.
本文综述了霉菌毒素杂色曲霉素的化学、物理和生物学特性。它必须被视为对温血动物有毒且具有致癌性。它很可能存在于食品中；因此，对其进行分析检测很有必要。参照已知的确证反应，本文描述了一种用于半定量测定水果和蔬菜中杂色曲霉素的方法。该方法通过硅胶柱色谱纯化后，借助薄层色谱法可检测出每千克食品中20微克的杂色曲霉素。通过用三氟乙酸酐处理使其衍生化为半缩醛来确证其同一性。该方法特别适用于食品的常规检测。
