Rapid chemical characterization and pharmacological mechanism of Fining Granules in the treatment of chronic bronchitis based on UHPLC-Q-exactive orbitrap mass spectrometer and network pharmacology.

Background: Less. is a perennial herb belonging to the Compositae family that has been used in traditional medicine as an antitussive and expectorant for treating chronic bronchitis and acute respiratory infections. Traditionally, Feining Granules are prepared from water extracts of the raw plant material.

The visualization of the spatial distribution of Cocculus orbiculatus based on air flow-assisted desorption electrospray ionization mass spectrometry imaging.

Cocculus orbiculatus (C. orbiculatus), the root of plants belonging to the Menispermaceae family, has been extensively used to treat various diseases, including malaria and rheumatism. The main chemicals in these plants are alkaloids; however, the spatial distribution of these compounds within the plant roots remains undefined.

Systemic chemical characterization of Lemna minor by UHPLC-Q-Exactive Orbitrap MS coupled with parallel reaction monitoring.

Lemna minor L. (LM) has been used for measles opacity, rubella itching, edema, and oliguria, and the main active ingredients were flavonoids, namely, apigenin, apigenin-7-O-glucoside, and luteolin-7-O-glucoside. However, few systematic analyses of their constituents have been performed; thus, it was necessary to establish a fast and efficient method to identify the chemical composition of LM.

Rapid characterization of the potential active metabolites of diacerein in rat plasma based on UHPLC-Q-exactive orbitrap mass spectrometry and molecular docking.

Diacerein, a competently semisynthetic diacetyl derivative of anthraquinone, is a nonsteroidal anti-inflammatory drug, which has been used for treating osteoarthritis and preventing vascular diseases. However, previous investigation indicated that diacerein metabolites and its metabolic pathway in vivo was still unclear. In this research, an effective method was established based on ultra-high-performance liquid chromatography coupled with Q-Exactive-Orbitrap mass spectrometer and molecular docking to screen and detect the potential active metabolites of diacerein in rat plasma after oral administration.

Rapid Characterization and Action Mechanism of the Antidiabetic Effect of L Using UHPLC-Q-Exactive Orbitrap MS and Network Pharmacology.

L, F. Ebenaceae, is an edible fruit that is widely distributed in China and other Asian countries. Presently, L can be used to treat patients with diabetes; however, its chemical composition and pharmacological profiles remain to be elucidated.

Comprehensive characterization of multiple components of using UHPLC-Q-Exactive Orbitrap Mass Spectrometers.

is the dried ripe fruit of the Rhamnaceae family; it is widely distributed in Shandong, Henan, Liaoning, and other places in China. In folk medicine, it was used to restore vital energy, as a blood tonic, and for the treatment of spleen deficiency. To date, a complete investigation of the compounds of has rarely been performed.

Reference genome assemblies reveal the origin and evolution of allohexaploid oat.

Common oat (Avena sativa) is an important cereal crop serving as a valuable source of forage and human food. Although reference genomes of many important crops have been generated, such work in oat has lagged behind, primarily owing to its large, repeat-rich polyploid genome. Here, using Oxford Nanopore ultralong sequencing and Hi-C technologies, we have generated a reference-quality genome assembly of hulless common oat, comprising 21 pseudomolecules with a total length of 10.
