摘　　要：目的调查分析河北省小麦、玉米及其制品中16种常见真菌毒素污染状况。方法收集河北省37份鲜(冻)玉米/玉米粒、74份玉米、玉米面制品以及240份小麦样品。样品经乙腈:水:甲酸(79:20:1, V:V:V)溶液超声离心提取后,通过同位素内标稀释法处理,采用液相色谱-串联质谱法进行检测。结果伏马毒素小麦检出8份,玉米、玉米面制品检出66份,检出范围为ND~3889.9μg/kg;玉米赤霉烯酮检出小麦检出2份,玉米、玉米面制品检出69份,检出范围为ND~323.2μg/kg;脱氧雪腐镰刀菌烯醇小麦检出122份,玉米、玉米面制品检出68份,检出范围为ND~4183.4μg/kg;3-乙酰基-脱氧雪腐镰刀菌烯醇小麦检出5份,玉米、玉米面制品检出18份;15-乙酰基-脱氧雪腐镰刀菌烯醇小麦检出12份,玉米、玉米面制品检出38份;其他毒素均为未检出。鲜(冻)玉米/玉米粒中16种真菌毒素均未检出。结论伏马毒素、玉米赤霉烯酮和脱氧雪腐镰刀菌烯醇为小麦、玉米及其制品的主要污染物,其污染状况应引起关注。Objective To investigate the contamination situation of 16 common mycotoxins in wheat,corn and their products from Hebei province.Methods Totally 37 fresh(frozen)corn/corn kernels,74 corn and corn flour products and 240 wheat samples were collected.The samples were extracted by ultrasonic centrifugation of acetonitrile:water:formic acid(79:20:1,V:V:V)solution,then treated by isotope internal standard dilution method,and detected by liquid chromatography tandem mass spectrometry.Results 8 samples of fumonisins were detected in wheat,66 samples were detected in corn and corn flour products,and the detection range was ND~3889.9μg/kg;2 samples were detected in wheat zearalenone,and 69 samples were detected in corn and corn flour products.The detection range is ND~323.2μg/kg;122 samples of deoxynivalenol wheat were detected,68 samples of corn and corn flour products were detected,and the detection range was ND~4183.4μg/kg;5 samples of 3-acetyl-deoxynivalenolwere detected in wheat,18 samples were detected in corn and corn flour products;12 samples of 15-acetyl-deoxynivalenolwere detected in wheat,38 samples were detected in corn and corn flour products;others Toxins were not detected.Conclusion Fumonisins,zearalenone and deoxynivalenol are the main pollutants of wheat,corn and their products,and their pollution status should be paid attention to.
