The mass spectral fragmentations of 2-methylsparteine (1), 2, 17-dimethylsparteine (2), 2-methyl-17-isopropylsparteine (3), 2-methyl-17-oxosparteine (4), 2-oxo-17-methylsparteine (17-methyllupanine) (5) and 2-oxo-17-isopropylsparteine (17-isopropyllupanine) (6) were investigated. Fragmentation pathways, whose identification was assisted by accurate mass measurements and a correlation between the abundances of the M(+.) and selected fragment ions of the investigated compounds, are discussed. The data obtained create the basis for distinguishing the structural isomers and metamers.
对2-甲基鹰爪豆碱（1）、2,17-二甲基鹰爪豆碱（2）、2-甲基-17-异丙基鹰爪豆碱（3）、2-甲基-17-氧代鹰爪豆碱（4）、2-氧代-17-甲基鹰爪豆碱（17-甲基羽扇豆碱）（5）和2-氧代-17-异丙基鹰爪豆碱（17-异丙基羽扇豆碱）（6）的质谱碎裂进行了研究。讨论了碎裂途径，这些途径的确定借助了精确质量测量以及所研究化合物的M(+.)和选定碎片离子丰度之间的相关性。所获得的数据为区分结构异构体和变构体奠定了基础。
