Analysis of phenolic compounds in rhubarbs using liquid chromatography coupled with electrospray ionization mass spectrometry
TLDR
A facile method based on liquid chromatography coupled with electrospray ionization tandem mass spectrometry has been established for the analysis of bioactive phenolic compounds in rhubarbs to clarify the chemical composition of rhubarb comprehensively for the first time. Expand
Characterization of phenolic compounds in the Chinese herbal drug Artemisia annua by liquid chromatography coupled to electrospray ionization mass spectrometry.
TLDR
The C-glycosyl flavonoids were reported from A. annua for the first time and they were found to be a new type of main constituents, and might be responsible for its antioxidant and antiviral activity. Expand
Characterization of phenolic compounds in the Chinese herbal drug Tu-Si-Zi by liquid chromatography coupled to electrospray ionization mass spectrometry.
TLDR
The large differences observed between the phenolic constituents of C. chinensis and C. australis strongly encouraged further comparison of the bioactivities of these two species. Expand
Detection, characterization and identification of phenolic acids in Danshen using high-performance liquid chromatography with diode array detection and electrospray ionization mass spectrometry.
TLDR
By using HPLC-diode array detection-electrospray ion trap tandem mass spectrometry (HPLC-DAD-ESI-MS(n) in negative ion mode), the fragmentation pathways of 11 phenolic acids which were isolated from Danshen are analyzed and new minor constituents were identified or tentatively identified for the first time.

Identification of Key Licorice Constituents Which Interact with Cytochrome P450: Evaluation by LC/MS/MS Cocktail Assay and Metabolic Profiling
TLDR
Several licorice constituents, viz., liquiritigen in, isoliquiritigenin, together with seven isoprenylated flavonoids and arylcoumarins, which could be key components responsible for the herb–drug interaction between cytochrome P450 and licorICE are identified. Expand
Characterization of flavonoids in the traditional Chinese herbal medicine-Huangqin by liquid chromatography coupled with electrospray ionization mass spectrometry.
TLDR
HPLC-DAD-ESI-MS(n) was used to analyze flavonoids in the roots of S. baicalensis and found two C-glycosides, apigenin-6-C-glucyl-8- C-arabinoside and chrysin- 6,8-di-C -glucoside, together with some O-glyCosides, are reported from S. Baicalensis for the first time. Expand
Simultaneous quantification of six major phenolic acids in the roots of Salvia miltiorrhiza and four related traditional Chinese medicinal preparations by HPLC-DAD method.
TLDR
The results indicated that the developed HPLC assay could be readily utilized as a quality control method for S. miltiorrhiza and its related traditional Chinese medicinal preparations. Expand

TLDR
A targeted post-acquisition data processing strategy, key ion filtering (KIF), to analyze untargeted mass spectral data to rapidly profile the chemical constituents of complicated herbal extracts. Expand
Qualitative and quantitative analysis of curcuminoids in herbal medicines derived from Curcuma species.
TLDR
A validated and sensitive HPLC-UV-MS method was developed for qualitative and quantitative analysis of curcuminoids in eight herbal medicines derived from four Curcuma species, and suggested that the contents of three major curcumedoids in different herbal medicines varied significantly. Expand
Microbial metabolism of artemisinin by Mucor polymorphosporus and Aspergillus niger.
TLDR
Five products of Artemisinin transformed by Mucor polymorphosporus and Aspergillus niger were identified as 9beta-hydroxyartemisinin, which are new compounds. Expand
