| 摘 要： | 建立了植物提取物中19种邻苯二甲酸酯类化合物(PAEs)的气相色谱-质谱(GC-MS)分析方法。样品经水溶解,正己烷提取,弗罗里硅土小柱净化,采用GC-MS法在选择离子监测模式(SIM)下进行测定。结果表明:方法在0.1～10 mg/kg范围内具有良好的线性关系,相关系数均大于0.999,检测限为0.14～1.2μg/kg,加标回收率为62.1%～118.2%,相对标准偏差为0.61%～13%。方法可满足植物提取物中PAEs的定性和定量测定。

| Abstract: | A gas chromatography-mass spectrometric method was developed for the determination of 19 phthalic acid esters(PAEs) in plant extracts.The samples were dissolved with water,extracted with hexane,cleaned-up by a Florisil column,and determined using GC-MS method in selected ion monitoring mode(SIM).The results showed that a good linear relationship was obtained in the range of 0.1～10 mg/kg,the correlation coefficients were larger than 0.999,the detection limits were 0.14～1.2 μg/kg,the recoveries were 62.3%～118.2%,and the relative standard deviations were 0.61%～13%.The method has the advantages of simple operation,high sensitivity,good reproducibility,and it can meet the requirements of plant extracts in the qualitative and quantitative determination of PAEs. |
