A rationally designed polymer (RDP) capable of recognizing α-tocopherol and other minor components in sunflower oil has been produced. It is known that sunflower oil is a source of various physiologically active compounds. Unfortunately, they are present in very minor quantities which make their purification from the complex oil matrix problematic. An extraction method presented here was developed with particular attention to the selectivity, efficiency and precision of the extraction process. The methacrylic acid-based RDP in combination with the optimised purification method allowed the extraction of α-tocopherol with 94% recovery. The synthesised polymer was used successfully to extract α-tocopherol together with other essential minor components of sunflower oil without any pre-treatment step. According to GC/MS, the compounds ‘harvested’ from sunflower oil using the developed polymer included palmitic, oleic and linoleic acids, α-tocopherol, campesterol, stigmasterol, and β-sitosterol.

使用合理设计的聚合物从葵花油中固相萃取α-生育酚和其他生理活性成分

已经生产出能够识别向日葵油中的α-生育酚和其他次要成分的合理设计的聚合物（RDP）。已知葵花籽油是多种生理活性化合物的来源。不幸的是，它们以很少的量存在，这使得从复杂的油基质中纯化成为问题。开发了一种此处提出的提取方法，并特别注意了提取过程的选择性，效率和精度。基于甲基丙烯酸的RDP与优化的纯化方法相结合，可提取α-生育酚，回收率为94％。合成的聚合物无需任何预处理步骤即可成功地用于提取α-生育酚和葵花籽油的其他必需微量成分。根据GC / MS，
