Duzhong Jiangya Tablet is a hypotensive drug. In this study, High-performance liquid chromatography-fourier transform-ion cyclotron resonance-mass spectrometry technology was used to quickly identify its chemical composition. SinoChrom ODS-BP column (250mm×4.6mm, 5μm) was used. The mobile phase was acetonitrile(A)-0.1% formic acid solution(B). The flow rate was 1 mL·min-1 . Extracted ion chromatogram was used to analyze the samples in positive and negative ion modes. Based on the obtained accurate mass spectrometry information such as excimer ions and fragment ions, combined with the reference substance and the reference literature, to identify the chemical constituents of Duzhong Jiangya Tablet. A total of 131 compounds were identified, including 4 types of penylpropanoids, 6 types of phenylethanoid glycosides, 10 types of organic acids, 14 types of iridoids, 12 types of lignans, 18 types of alkaloids, 7 types of coumarins, and 60 kinds of flavonoids. This established method can quickly and efficiently identify chemical constituents in Duzhong Jiangya Tablet, and lay a foundation for the research on the efficacy and quality of this traditional Chinese medicine, and provide a reference for the characterization of the chemical constituents of other traditional Chinese medicine preparations.

Abstract Endothelial dysfunction plays important roles in vascular dysfunction under diabetic conditions. The generation of advanced glycation end products (AGEs), which can induce inflammation and oxidative stress, is pivotal in endothelial dysfunction. Salidroside, a major active compound in Rhodiola rosea, exerts protective effects against vascular diseases. To study the effects and mechanism of salidroside in diabetes-induced vascular endothelial dysfunction, an in vitro model was establishe...

Abstract Flos Lonicerae Japonicae(Jinyinhua) possesses clearing heat and detoxification activity, and has been used as a traditional Chinese medicine to treat influenza for many years. Due to the complex chemical composition and diverse content of Jinyinhua, especially the many trace ingredients, the effective components are unknown. In this study, an improved two-dimensional high performance liquid chromatography-ultrafiltration combined with electrospray ionization-time-of-flight/mass spectros...

Abstract Eucommia ulmoides Oliv. (E. ulmoides) is a kind of plant with high medicinal value, there are known as the “gold plants”. Some components and contents of barks and branches from E. ulmoides are similar, the barks are mainly used as medicine, but the branches have not been systematically studied and were discarded. In this paper, five fractions extracted from E. ulmoides branches were detected by the classical anti-complement activity assay in vitro. The n-butanol fraction of E. ulmoides...

ABSTRACT Danhong Injection (DHI) is a Chinese medicine patent drug to treat cardiovascular diseases. It is derived from the herbal medicines Dan-shen and Hong-hua. The bioactive compounds of DHI are polar phenolic acids and flavonoid glycosides. Thus far, the contents of major compounds in DHI are not well understood, and the identification of minor compounds lacks rapid methods. In this work, quantitative and qualitative analyses of DHI compounds were performed using ultra-high performance liqu...

In this study, Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), combined with quadrupolar detection (QPD), was applied for online liquid chromatography (LC) MS analysis of natural organic matter (NOM). Although FT-ICR MS has emerged as an important analytical technique to study NOM, there are few previous reports on online LC FT-ICR MS analysis of NOM due to the long acquisition time (2–8 s) required to obtain high-resolution mass spectra. The QPD technique provides a cri...
