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.

• 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。
