摘　　要：探讨了3种不同提取甘蔗中3-硝基丙酸的方式,并通过对提取时间及甲酯化时间进行优化研究,建立了甘蔗中3-硝基丙酸的气相色谱-质谱联用检测方法,该方法在20μg/L~500μg/L浓度范围内有良好的线性关系,检出限为2μg/kg,定量限为8μg/kg;正常食用含有微量的3-硝基丙酸的甘蔗不会对人体产生毒害。Three different methods for extracting 3-NPA from sugarcane were explored.Meanwhile a gas chromatography-mass spectrometry detection method for 3-NPA in sugarcane was established by optimizing the extraction time and methylation time.The method showed a good linear relationship in the concentration range of 20μg/L~500μg/L,with a detection limit of 2μg/kg and a quantification limit of 8μg/kg.Normal consumption of sugarcane containing trace amounts of 3-NPA will not cause toxicity to the human body.
