用电喷雾傅立叶变换离子回旋共振质谱仪分别研究了以α-环糊精、β-环糊精和γ-环糊精作为手性拆分剂对手性托品烷的手性区分效应,实验结果表明β-环糊精具备较α-环糊精和γ-环糊精更强的手性区分能力,β-环糊精和托品烷的二聚体复合物离子的强度随激发能量的变化和托品烷对映体含量值呈现出一定的线性关系.

Electrospray Fourier transform ion cyclotron resonance mass spectrometry was used to investigate chiral molecular recognition of tropine using α-cyclodextrin, β-cyclodextrin and γ-cyclodextrin, as chiral selectors. Chiral recognition ability of three cyclodextrins was revealed by the mass spectra based on the protonated complexes of tropine with cyclodextrins. Protonated tropine ion was formed when the dimeric complex of tropine with cyclodextrin underwent collision-induced dissociation (CID). Chiral recognition of cyclodextrin was assessed by changing activation attenuation/activation pulse length.

Key words: cyclodextrin, complex, electrospray, Fourier transform ion cyclotron resonance mass spectrometry
