1. With eating healthy are getting more popular, diners look for more diversity in what kind of foods they eat. The safety of tea gradually become to people's attention in this era.
首先参照国内外标准，先对天狮牌减肥茶加乙腈进行萃取，经过匀浆混合，离心收集上清液。再分别通过固相萃取柱Envi-18,Envi-Carb和Sep-2.
Following domestic and foreign testing standards, we first extracted the Tian-Shi brand weight losing tea with acetonitrile, homogenized, and collected supernatant after centrifuge, and did sample preparation using solid phase extraction columns Envi - 18, Envi - Carb and Sep-pak amminopropyl columns, to enrich methyl chlorpyrifos. The collected liquids were concentrated with a water-bath under reduced pressure. By using this method the baseline matrix effect of tea can be minimized. This also reduced the adverse effects from active components in the tea. The concentrated samples were further extracted with n-hexane, then analyzed and validated with a Triple Quadrupole GC/Mass Spectrometry instrument.
