| 英文摘要 | Electrospray ionization ion-trap tandem mass spectrometry (ESI-MSn) was first employed for reinvestigating the structures of hupehensis saponin F and G previously isolated from Anemone hupehensis in our lab. Hupehensis saponin G was determined to contain one more trisaccharide unit (Rha-(1 -> 4)-Glc-(1 -> 6)-Glc-), not a glucose residue, than saponin F based on their molecular weights deduced from their [M+Na](+) ions in ESI-MS spectra. The (2,4)A(4 alpha)-ion at m/z 551.3 formed by retro-Diels-Alder (RDA) rearrangement in positive mode illustrated that the C-28 sugar chains of the two saponins were composed of trisaccharide repeating moieties with (1 -> 4) linkages rather than (1 -> 3) linkages. The interpretation of 2D-NMR spectra of the two compounds also confirmed the results obtained by ESI-MSn. Moreover, from the water soluble part of A. hupehensis, two novel triterpene saponins were tentatively characterized to contain 4 and 5 (1 -> 4)-linked above trisaccharide repeating moieties at C-28 position according to their ESI-MSn behaviors, respectively.
