新型降血胆固醇的物质MonacolinK的质谱研究

Study on Mass Spectrometry of A New Hypocholesterolemic Agent Monacolin K

本文报告了新型降血胆固醇的物质 Monacolin K的 EI谱和 FAB谱 ,并根据高分辨质谱 ( HRMS)数据讨论了主要特征碎片离子的裂解途径。 m/z 2 2 4碎片离子可能来自 3氢原子的重排的结果。

In this paper EI and FAB mass spectra of a new hypocholes terolemic agent monacolin K were measured.Their Mass Spectra fragmentations of characteristic fragmentions were discussed on the basis of high resolution Mass spectra data.m/z 224 fragmention probably results from a rearrangement of three hydrogens.
