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。 A GC-MS method was developed for the determination of 19 phthalate esters (PAEs) in plant extracts. Samples were dissolved in water, extracted with n-hexane and purified with Florisil. The samples were determined by GC-MS under selective ion monitoring mode (SIM). The results showed that the method had good linearity in the range of 0.1-10 mg / kg, the correlation coefficient was greater than 0.999, the detection limit was 0.14-1.2 μg / kg, the recoveries were in the range of 62.1% -118.2%, the relative standard deviations were 0.61% ~ 13%. Methods to meet the qualitative and quantitative determination of PAEs in plant extracts.
