The separation of chamazulene from hydrophilic contaminants present in blue tansy oil provides a visually engaging example of two common techniques: extraction and thin-layer chromatography (TLC). This application uses liquid CO₂ as a lipophilic solvent to pull a brilliant blue hydrocarbon molecule, chamazulene, out of or through a common hydrophilic material, cellulose. Yellow-green, hydrophilic components remain in a cotton ball or at the lower end of a paper strip. In dramatic fashion, the separation of colored components of blue tansy oil is accomplished with an environmentally sustainable solvent, CO₂, and an innocuous support material, cellulose. We believe this is the first reported use of liquid CO₂ in centrifuge tubes to conduct TLC.

离心管中的液态CO ₂：通过萃取和薄层色谱法从蓝艾菊油中分离去甲苯磺灵

从蓝色艾菊油中存在的亲水性污染物中分离出甲磺灵，这是两种常见技术的引人注目的例子：萃取和薄层色谱法（TLC）。此应用程序使用液态CO ₂作为亲脂性溶剂，从一种或多种常见的亲水性材料纤维素中拉出亮蓝色的烃分子Chamazulene。黄绿色的亲水性成分保留在棉球中或纸条的下端。蓝色艾菊油中有色成分的分离以一种环境可持续的溶剂CO ₂和无害的支撑材料纤维素来完成。我们相信这是首次报道在离心管中使用液态CO ₂进行薄层色谱法。
