| 中文摘要 | fragmentation pathways of nine flavone compounds have been studied by using electrospray ionization multi-stage tandem mass spectrometry (esi-msn). analyzing the product ion spectra of flavonoids and aglycones, we observed some diagnostic neutral losses, such as *ch3, h2o, residue of glucose and gluconic acid, which are very useful for the identification of the functional groups in the structures. furthermore, specific retro diels-alder (rda) fragments for flavones with different hydroxyl substitution have also been discussed. the information is helpful for the rapid identification of the location site of hydroxyl substitution on flavones. fragmentation pathways of c-glycosidic flavonoid have also been discussed using esi-msn, demonstrating ions [m-h-60](-), [m-h-90](-), [m-h-120](-) are characteristic ions of c-glycosidic flavonoid. according to the fragmentation mechanism of mass spectrometry and hplc-ms data, the structures of seven flavones in scutellaria baicalensis georgi have been identified on-line without time-consuming isolation. the hplc-esi-msn method for analyzing constituents in the scutellaria baicalensis georgi has been established. |
