Abstract: In this research the cracking situation of a series of C-glycosyflavonnes compounds was analyzed by the ESIMS-MS chromgraphy technology. The results showed that the ion peaks of [M-H-60]–, [M-H-90]– and [M-H-120]– were found in C-glycosyflavonnes with hexose and the ion peaks of [M-H-60]– and [M-H-90]– were obtained in the choromgraphy of ESIMS-MS on C-glycosyflavonnes with pentose. Conclusively, C-glycosyflavones had their own craking law by C-glycosyflavonnes chromagraphy method which is helpful in finding some new and trace C-glycosyflavonnes compounds.
