aforementioned compound classes. Enantioresolution was achieved by simply adding native β‐cyclodextrin, acetyl‐β‐cyclodextrin, 2‐hydroxypropyl‐β‐cyclodextrin, or carboxymethyl‐β‐cyclodextrin as chiral selector additives to the background electrolyte. Fifty‐one chiral NPS served as analytes mainly purchased from online vendors via the Internet. Using 10 mM of the aforementioned β‐cyclodextrins in a 10 mM

is little knowledge in terms of clinical studies about possibly different effects of the two enantiomers of novel amphetamine derivatives. For this reason, there is a big demand for enantioseparation method development of this new substance class.Regarding gaschromatography, cyclodextrins proved to be effective for enantioseparation of NPS. In our attempt, an Astec® Chiraldex™ G‐PN column containing
在不同的物质类别中,新型精神活性物质 (NPS) 包括具有兴奋和共情作用的手性安非他明。关于新型苯丙胺衍生物的两种对映体可能具有不同作用的临床研究知之甚少。因此,对这一新物质类别的对映体分离方法的开发有很大的需求。在气相色谱方面,环糊精被证明对于NPS的对映体分离是有效的。在我们的尝试中,含有 2,6-二-O-戊基-3-丙酰基-γ-环糊精的 Astec® Chiraldex™ G-PN 色谱柱和含有庚基-(2,6-二-O-戊基) 的 Lipodex™ D 色谱柱‐O-乙酰)-β-环糊精作为手性选择剂,在岛津 GCMS-QP2010 SE 系统中用作固定相。由于特殊的涂层,最高温度限制为 200 °C 等温或 220 °C 程序模式。为了确保检测,使用三氟乙酸酐 (TFAA) 来增加样品挥发性。 1结果,对 35 种安非他明作为其 TFAA 衍生物进行了测试。采用从 140 °C 到 200
