有机质谱学在厚朴酚与和厚朴酚结构确定中的应用
Applications of Organic Mass Spectrometry in Structure Elucidation of Magnolol and Honokiol
【摘要】 采用超临界CO2提取方法对厚朴药材的化学物质进行提取,用毛细管气相色谱-质谱联用技术(GC/MS)对提取物进行分析。在厚朴酚与和厚朴酚的质谱中,其分子离子峰M.+(m/z266)均为基峰,主要碎片峰m/z237、184、165、91、77都相一致,而碎片峰m/z247是区别厚朴酚与和厚朴酚化学结构的典型质谱特征。
【Abstract】 Chemical substances of Magnolia(officinalis) were extracted by supercritical CO2 method.The extract was analyzed by capillary gas chromatography combined with mass spectrometric detection(GC/MS).In the mass spectra of both magnolol and honokiol,the both molecular ion peaks at m/z 266(M·+) are the basic peaks.The main fragment peaks at m/z 237,184,165,91,77 are the same.But the fragment peak at m/z 247 is the typical characteristic of the mass spectra to differentiate the chemical structures between magnolol and honokiol.
