采用电喷雾多级质谱方法, 研究了三个从地衣中提取到的缩酚酸醚类化合物在电喷雾电离质谱中的裂解行为, 结果表明它们在电喷雾多级质谱中能得到较多碎片离子, 其裂解途径能体现它们的基本结构特征.

关键词: 缩酚酸醚, 电喷雾电离质谱, 多级质谱, 裂解行为

The mass spectrometric behavior of three depsidones isolated from Lichen was studied by electrospray tandem mass spectrometry, showing that these compounds in ESI-MSn could produce many daughter ions. Their fragmentation pathways reflected their structural character.

Key words: depsidone, ESI-MS, MSn, fragmentation pathway
