A quick analytical method for determining 18 phthalic acid esters (PAEs) in edible oil was developed by liquid chromatography - tandem mass spectrometry (LC-MS/MS).The PAEs were extracted with acetonitrile and purified by Liquid-liquid extraction with N-hexane,followed by LC-MS/MS.With the optimized condition,the limits of quantification (LOQ) of the 18 PEAs analytes were 0.05-0.5 mg/kg.The overall recovery varies from 53.4% to 107.9%,and the relative standard deviations (RSD) were between 7.2% and 24.6%.

有机锡化合物和蛋白的结合通常也是有机锡化合物与蛋白半胱氨酸和组氨酸的结合.实验证明,有机锡化合物不仅能与细胞膜上的蛋白反应,也可以与细胞内蛋白反应[1,2].这些反应是根据有机锡和氨基酸的配位反应进行的.有机锡化合物与生物分子的相互作用,是其毒性产生的主要原因.
橘,或称橘子,是芸香科柑桔属植物橘C.reticulata 的成熟果实,通过研究发现柑橘属植物中含有丰富的黄酮类化合物,其中橙皮苷是该植物中重要的活性成分,具有抗氧化、抗肿瘤、抗炎、扩张血管、降低血脂等多种功效.目前橙皮苷的检测主要针对枳实,陈皮等样品,并没有橘子果肉中含量测定的研究报道.本实验选取橘子的果肉为研究对象,通过对提取方法优化,采用HPLC 测定了橘子果肉中橙皮苷的含量,从而为橘子功效
