中文摘要：2011-2012年期间，共从突尼斯市场收集了64份高粱样本（37份突尼斯高粱样本和27份埃及高粱样本）。通过高效液相色谱-荧光检测法（HPLC-FLD）分析样品中黄曲霉毒素B1，赭曲霉毒素A和玉米赤霉烯酮的污染。在38个样品中发现黄曲霉毒素B1，浓度范围为0.03-31.7μg kg（-1）。在24个样品中检测到赭曲霉毒素A，浓度范围为1.04至27.8μg kg（-1）。在21个样品中检测到玉米赤霉烯酮，浓度在3.7和64.5μgkg（-1）之间变化。对于所研究的三种霉菌毒素，对原产国之于研究样本中霉菌毒素的发生率和浓度的影响进行方差分析，显示两批样品之间没有显著差异（P> 0.05）。研究的三种霉菌毒素都污染了高粱，并且由于该谷物中真菌生物的多样性，它们也可能共存。
外文摘要：A total of 64 samples of sorghum (37 Tunisian sorghum samples and 27 Egyptian sorghum samples) were collected during 2011-2012 from markets in Tunisia. Samples were analysed for contamination with aflatoxin B1, ochratoxin A and zearalenone by High-Performance Liquid Chromatography Coupled with Fluorescence Detection (HPLC-FLD). Aflatoxin B1 was found in 38 samples in the range 0.03-31.7 mu g kg(-1). Ochratoxin A was detected in 24 samples with concentrations ranging from 1.04 to 27.8 mu g kg(-1). Zearalenone was detected in 21 samples and the concentration varied between 3.7 and 64.5 mu g kg(-1). ANOVA analysis of the influence of the country of origin on the incidence and concentration of mycotoxins in the samples studied showed no significant difference (P>0.05) between the two batches of samples for each of the three mycotoxins studied. The studied mycotoxins contaminate sorghum and may also co-exist because of the diversity of the mycobiota in this cereal.
