ESI-MS spectra of 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)-pyridinoneselectrospray ionizationsubstituted pyridinonestandem mass spectrometryTwelve 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)-pyridinones were investigated by tandem mass spectrometry using positive as well as negative ...
Electrospray tandem mass spectrometry (ESI-MS/MS) is commonly used in high throughput metabolomics. One of the key obstacles to the effective use of this technology is the difficulty in interpreting measured spectra to accurately and efficiently identify metabolites. Traditional methods for automated met...

Compound 1 and compound 2 were characterized as lucenin-2 and vicenin-2 based on UV and ESI-MS spectra, that showed deprotonated molecule at m/z 609 and m/z 593, respectively, as well as the MS/MS fragmentation pattern, identical to those previously described by Abranko et al. Antinocic...

刚才刚用ESI-MS测了两个样,请问大家怎么把原始的数据导出来啊?各位大侠支个招啊!咋没动静呢!
Actually, the mix- ture could be analyzed directly in a HPLC-MS hyphen- ated system, provided a suitable NaCl solution is added as an additive in the HPLC eluents or as a post-column make-up liquid. The ESI spectra of the three pure compounds (labeled peak 1, 2, and 3) were ...
To answer the first question, the ESI-MS/MS spectra were taken of ions containing demethoxycurcumin, curcumin, and metal cation (e.g., ion [dCurc + Curc-H + Pb]+), and in order to answer the second question the ESI-MS/MS spectra were recorded of ions containing demethoxycurcumin ...
Furthermore, ESI-MS spectra were uncomplicated by fragmentation of molecular ions and showed unambiguous single peaks for each species present and, consequently, interpretation of spectra was straightforward. The progress of reactions could be monitored over time by following the gradual appearance and ...
