| 中文摘要 | the effect of metal (li+, na+, k+, ag+) cationization on collision-induced dissociation of ginsenosides was investigated by electrospray ionization mass spectrometry combined with multi-stage mass spectrometry (esi-msn). the fragments of sodiated and lithiated molecules give valuable structural information regarding the nature of the aglycone and the sequence and linkage information of sugar moieties. however, the number and relative abundances of fragment ions from lithiated ginsenosides are significantly greater than for the sodiated species, the k+ adducts undergo glycosidic cleavages and very limited cross-ring reactions. the silver ion adducts fragment mainly through glycosidic cleavages. copyright (c) 2001 john wiley & sons, ltd. |
