摘　　要：目的对新型抗胆碱能M受体阻断剂结构类似物噻环壬酯(TC)进行深入研究。方法采用电子轰击质谱(EI-MS)、电喷雾电离质谱(ESI-MS)2种质谱技术分别对TC的结构和裂解途径进行实验。结果用ESI-MS获得m/z364[M+H]+、m/z156等质谱峰,用EI-MS获得m/z363[M]+、m/z138、m/z181、m/z154、m/z221等质谱峰,并解释了其中的主要特征碎片离子。结论TC的EI-MS质谱和ESI-MS质谱中所出现的主要碎片离子峰都与其结构式中的主要骨架片段符合,所有的重要碎片峰均得到了满意的解释。Objective Thiencynonate（TC） is a novel compound which is similar to anti-cholinergic drug developed by Institute of Pharmacology and Toxicology, used for the prevention and treatment of motion sickness or other disease caused by imbalance of function under movement stimulation and the pesticides poison of organic phosphorus. Methods For further study on it, the mass spectrometry techniques of electron ionization mass spectrometry（EI-MS） and electron spray ionization mass spectrometry（ESI-MS） were used for the elucidations of the structure and fragmentation pathway of TC. Results The results shows the molecular ion peak m/z 364 [ M ＋ H ] ^＋ , m/z156, were detected by ESI-MS; m/z363 [ M]^＋ and m/z138,m/z181 and m/z154, m/z221 were detected by EI-MS. Further more, the fragmentation pathway of TC was also explained. Conclusion The results provided a valuable information for the investigation and development of drugs similar to TC.
