Systematic analysis of main constituents in rat biological samples after oral administration of the methanol extract of Fructus Aurantii by HPLC-ESI-MS/MS
High performance liquid chromatography (HPLC) with diode array detection (DAD) and electrospray ionization tandem mass spectrometry (ESI/MS/MS) was used to analyze the main components in the methanol extract of Fructus Aurantii (FA) and the metabolites in rat biological samples after oral administration of the methanol extract of FA. There were 31 constituents identified in the extract of FA in...

متن کاملAnalysis of Chemical Constituents of Melastoma dodecandrum Lour. by UPLC-ESI-Q-Exactive Focus-MS/MS.
The ethnic drug Melastoma dodecandrum Lour. (MDL) is widely distributed throughout South China, and is the major component of Gong Yan Ping Tablets/Capsules and Zi Di Ning Xue San. Although the pharmacological effects of MDL have been well documented, its chemical profile has not been fully determined. In this study, we have developed a rapid and sensitive UPLC-ESI-Q-Exactive Focus-MS/MS method...
متن کاملStructural Analysis of -Carrageenan Sulfated Oligosaccharides by Positive Mode Nano-ESI- FTICR-MS and MS/MS by SORI-CID
Structural analysis of sulfated oligosaccharides from -carrageenan of up to ten residues (MW 2 kDa) was successfully carried out by positive mode nano-ESI-FTICR-MS together with MS/MS using sustained off-resonance irradiation-collision induced dissociation (SORI-CID). Glycosidic bond cleavage reactions via the Band Y-types of fragmentation were observed and enabled complete sequencing of the ol...
متن کاملFast Analysis of Chlorinated Phenoxy Herbicides in Environmental Samples by Negative ESI LC-MS/MS – 14337
This paper describes the analysis procedure and results for environmental herbicide samples by a negative ESI LC-MS/MS method. After the preparation of aqueous and soil samples, the extracts are directly injected into a high performance liquid chromatography system coupled to negative eletrospray ionization (ESI-) tandem mass spectrometry. The sample preparation incorporates modified hydrolysis...
