Characterization Four Kinds of Alkaloids in Strychnos nux-vomica by HPLC-ESI-MS-MS
Objective:To analyze and identify the alkaloids in Strychnos nux-vomica.Method: HPLC-ESI-MS-MS was adopted to induce the characteristic fragmentation pathways of four kinds of alkaloid reference standards
which was applied to identify the alkaloids in S.nux-vomica.Result: The diversities of their structures lead to different ESI-MS-MS fragmentation.According to the fragmentation pathways
retention times
mass charge ratio and MS-MS data
eighteen alkaloids including 8 strychnine type
2 pseudo type
5 N→O type and 3 N-Me type were identified from the extract of S.nux-vomica.Conclusion: This study is helpful for the quality analysis and control of the extract of S.nux-vomica.
