| 英文摘要 | steroidal saponins are the major bioactive constituents of dioscorea zingiberensis c h wright (d zingiberensis) in this work, ultra-performance liquid chromatography/electrospray ionization quadrupole time-of-flight tandem mass spectrometry (uplc/q-tof-ms/ms) was applied to the separation and characterization of steroidal saponins in crude extracts from d zingiberensis. the results showed that fragment ions from glycosidic and cross-ring cleavages gave a wealth of structural information related to aglycone skeletons, sugar types and the sequence of sugar units. according to the summarized fragmentation patterns, identification of steroidal saponins from d zingiberensis could be fulfilled, even when reference standards were unavailable as a result, a total of thirty-one saponins with five aglycone skeletons, including fourteen new trace saponins, were identified or tentatively elucidated in crude extracts from d zingiberensis based on their retention times, the mass spectrometric fragmentation patterns, and ms and ms/ms data (c) 2010 elsevier b v all rights reserved |
