Abstract
: The Wen-Jing decoction, a traditional Chinese medicine formula, has been used as a blood-activating and stasis-eliminating drug to treat gynaecological syndromes, such as dysmenorrhea, amenorrhea, and menstrual disorders. However, its pharmacodynamic material basis and mechanism of action have not been thoroughly elucidated to date. The goal of this study was to characterize and identify multiple constituents and metabolites in Wen-Jing decoction. An ultra high performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry method was established and validated in the present study for the first time. A total of 101 compounds, including 11 monoterpene glycosides, 19 flavonoids, 49 triterpene saponins, 5 phthalides, 3 phytoecdysones, and 14 others, were unambiguously or tentatively characterized by comparing their retention times and MS data with reference standards or with data reported in the literature. After oral administration of Wen-Jing decoction, 27 compounds, including nine prototype compounds and 18 metabolites were detected in rat plasma. Thus, the ultra high performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry method was found to be efficient for in-depth structural elucidation of chemical compounds in complex matrices of herbal medicines, which will provide useful chemical information for quality control and mechanism-of-action research.

Abstract Ligustici Rhizoma et Radix (LR), known as Gaoben (GB) in Chinese, has been used in traditional Chinese medicine for more than 2000 years. However, the varieties of LR are not well characterized at present, and traditional recognition methods have encountered increasing difficulties. This research attempts to distinguish different varieties of LR and its adulterants based on their chemical composition. A total of 61 representative samples were collected, and their varieties were confirme...

Abstract Paeonol, an active constituent in the root bark of Paeonia suffruticosa Andrews, is used to treat inflammation, headache and other diseases in clinic. Though the data on pharmacological researches of paeonol abounds, its metabolic profile is not so clear. It is essential to systematically characterize the in vivo metabolites in order to better understand its mechanism of action. In this study, ultra performance liquid chromatography coupled with electrospray ionization quadrupole time-o...

An ultra high performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry method in both positive and negative ion modes was established in order to comprehensively investigate the major constituents in Wu-Ji-Bai-Feng-Pill. Briefly, a Waters ACQUITY UPLC HSS C18 column was used to separate the aqueous extract of Wu-Ji-Bai-Feng-Pill. 0.1% formic acid in acetonitrile and 0.1% aqueous formic acid v/v were used as the mobile phase. All analytes ...

Wendan decoction, a classical traditional Chinese medicine formula consisting of six herbal medicines, has been widely used in clinical treatments for thousands of years due to the expectorant effects. However, the chemical basis of Wendan decoction remains unclear, which hinders the elucidation of the scientific connotation and mechanism of its effective components. In this study, an ultra-high performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry met...

Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive brain-stimulation technique that transiently modulates cerebral cortex excitability, achieving overall positive results in poststroke motor-function recovery. Excessive inhibition of the ipsilesional-affected hemisphere by the contralesional-unaffected hemisphere has seriously hindered poststroke motor-function recovery. Hence, intracortical disinhibition can be used as an approach to managing poststroke brain injury. This tech...
