隐丹参酮的电子电离和电喷雾电离质谱分析

Analysis of Cryptotanshinone by Electron Spray Ionization Mass Spectrometry and Electron Ionization Mass Spectrometry

采用电喷雾电离质谱(ESI-MS)和电子轰击质谱(EI-MS)两种质谱技术,对隐丹参酮的结构和裂解途径分别进行了研究。采用EI-MS获得m/z296[M]+、281、268、253、235、225等质谱峰,采用ESI-MS获得m/z297[M+H]+、268、254、251等质谱峰,并用Mass Frontier 3.0软件辅助解析了其中的主要特征碎片离子以及裂解途径。

Electron Spray Ionization Mass Spectrometry （ESI-MS） and Electron Ionization Mass Spectrometry （EI-MS） were used to elucidate the structure and fragmentation pathway of Cryptotanshinone（CT）. Ion peak rn/z 296[M]^＋ ,281,268,253,235,225 were detected by EI-MS, andm/z297[M＋H]^＋,268,254,251 were detected by ESI-MS. The fragmentation pathway of CT was explained by the program of Mass Frontier 3.0.
