A new method of MS/MS(ALL) was designed to sequentially record a MS2 spectrum at each unit mass window through gas phase fractionation concept, so as to offer an opportunity for universal MS2 spectral recording with direct infusion(DI). As a proof-of-concept, DI-MS/MS(ALL) was applied for rapid chemome profiling of a famous herbal medicine named Lonicerae Japonicae Flos. After each MS2 spectrum was correlated to its precursor ion, the structural annotation was conducted by applying well-defined mass cracking rules, matching the mass spectral data with literatures and referring to those accessible databases. As a result, a total of 54 components were identified from Lonicerae Japonicae Flos extract, including 21 phenolic acids, 13 flavonoids, 12 iridoids, 4 triterpenoids and 4 other compounds. Therefore, DI-MS/MS(ALL) is a powerful tool for comprehensive, rapid qualitative analysis of chemical profiles of traditional Chinese medicine and other chemical components of complex systems.
设计了一种新的MS/MS(ALL)方法，通过气相分级概念在每个单位质量窗口顺序记录MS2谱，从而为直接进样（DI）进行通用的MS2谱记录提供了机会。作为概念验证，DI-MS/MS(ALL)被应用于著名草药金银花的快速化学物质剖析。在将每个MS2谱与其前体离子相关联后，通过应用明确的质量裂解规则、将质谱数据与文献匹配并参考那些可访问的数据库进行结构注释。结果，从金银花提取物中总共鉴定出54种成分，包括21种酚酸、13种黄酮类、12种环烯醚萜、4种三萜类和4种其他化合物。因此，DI-MS/MS(ALL)是用于中药化学轮廓及复杂体系其他化学成分综合、快速定性分析的强大工具。
