Therapeutic Effects of on Ulcerative Colitis: Insights into Mechanisms of Action through Metabolomics and Microbiome Analysis.

Ulcerative colitis (UC), belonging to inflammatory bowel disease (IBD), is a chronic and relapsing inflammatory disorder of the gastrointestinal tract, which has not been completely cured in patients so far. is a Chinese medicine used clinically to treat "diarrhea," which is closely related to UC. This study was to elucidate the therapeutic effects of extract (VJE) on dextran sodium sulfate (DSS)-induced UC in mice and its underlying mechanism.

Separation and identification of terpene-conjugated curcuminoids based on liquid chromatography-tandem mass spectrometry and their in vitro anti-inflammatory activities.

Terpene-conjugated curcuminoids are conjugates of curcuminoids and bisabolanes in the rhizomes of Curcuma longa L. The fragmentation pathways of known three terpene-conjugated curcuminoids (bisabolocurcumin-ether, bisabocurcumin, and demethoxybisabolocurcumin ether) and curcumin, demethoxycurcumin, and bisdemethoxycurcumin were investigated using high-performance liquid chromatography-electrospray ionization tandem mass spectrometry in negative mode to rapidly search and discover similar unknown compounds of the acetone fraction of turmeric. Subsequently, compounds 1-3 were founded in the acetone fraction based on molecular weight and above fragmentation pathways (the characteristic fragment ions, the most and second most abundant fragment ions produced in MS spectra).

Lignans from the root of and their biological evaluation.

Investigation on the chemical components of Jones (Caprifoliaceae), a new lignan with pyran-ring, dipsalignan G (), along with eight known compounds (-) were isolated. Their structures were elucidated by extensive analysis of 1D, 2D NMR and HR-ESI-MS spectroscopic data. Additionally, possible biosynthetic pathway of was proposed.

Systematical Ingredient Investigations of Bur. Fruit and Immunoregulatory and Antioxidant Effects of Different Fractions.

Although the fruit of Bur. has been consumed by montanic people in China for centuries, its chemical and biological composition was still unclear. A series of comprehensive investigations on its chemical constituents and bioactivities were carried out for the first time.

Review of lignans from 2019 to 2021: Newly reported compounds, diverse activities, structure-activity relationships and clinical applications.

Lignans, with various biological activities, such as antitumor, antioxidant, antibacterial, and antiviral activities, are widely distributed in nature and mainly exist in the xylem of plants. In this paper, we summarized the structures and bioactivities of lignans reported in recent years (2019-2021) from five parts, including (1) a summary and classification of newly reported compounds; (2) the pharmacological activities of lignans; (3) molecular resources and activity distribution; (4) the structure-activity relationships; and (5) the clinical application of lignans. This review covers all undescribed compounds that were reported within the covered period of time and all bioactivity data about previously isolated lignans.

Quality Status Analysis and Intrinsic Connection Research of Growing place, Morphological Characteristics, and Quality of Chinese Medicine: Cyperi Rhizoma (Xiangfu) as a Case Study.

Materials And Methods: The macroscopic characteristics of CR as well as its moisture, ethanol extract, essential oil, total ash, and acid-insoluble ash contents were examined and calculated. In addition, qualitative identification and quantitative determination of -cyperone, cyperotundone, and nootkatone were simultaneously performed, and a high-performance liquid chromatography (HPLC) fingerprint chromatogram was established. Inductively coupled plasma mass spectrometry and gas chromatography methods recorded in ChP were used to measure the contents of residues of heavy metal and deleterious elements as well as residues of organochlorine pesticide, respectively.

Recent research progress of Cirsium medicinal plants in China.

Ethnopharmacological Relevance: The species of the genus Cirsium have been used as traditional Chinese medicine for hundreds of years. It is believed that Cirsium has the efficacies of cooling blood and stopping bleeding, dispelling blood stasis, detoxifying and eliminating carbuncle. At present, they are mainly used in treatment of the hemoptysis, hematemesis, hemoptysis, hematuria, traumatic bleeding and Henoch-Schonlein purpura.

Structures of fructan and galactan from Polygonatum cyrtonema and their utilization by probiotic bacteria.

Polygonatum cyrtonema is a known tonic herb in Chinese Materia Medica, extensively consumed in China, but the structure and activity of its polysaccharide components remain to be clarified. Herein, two new polysaccharides (a fructan and a galactan) were purified from the dried and the processed P. cyrtonema rhizome, respectively.

Modulation of the 5-HTA receptor current by desacylbaldrinal.

The serotonin (5-hydroxytryptamine) type 3 receptor is an important target in the control of digestive dysfunction such as anorexia and bulimia, and 5-HT receptor antagonists are effective against eating disorder and the early-phase chemotherapy and radiotherapy evoked vomiting. Our previous research of revealed the presence of iridoids, which showed potent antitumor activities. Here, we explored the effects of 10π aromatic iridoid desacylbaldrinal isolated from on the 5-HT receptor current.

A new abietane diterpenoid glycoside from var. .

A new abietane diterpenoid glycoside, ajugaside B (), along with three known compounds (), were isolated from the whole plants of var. . The structure of the new compound () was elucidated by means of spectroscopic analyses (HRESIMS, IR, NMR and ECD).

Two new coumarins from Herpetospermum caudigerum.

The ethyl acetate extract from the seeds of Herpetospermum caudigerum was found to show protective effects on carbon tetrachloride (CCl(4)) and thioacetamide (TAA)-induced acute hepatic injuries in mice. From the ethyl acetate extract, two new coumarins, herpetolide A (1) and herpetolide B (2), along with four known compounds, herpetone (3), dehydrodiconiferyl alcohol (4), 2,4-dihydroxypyrimidine (5) and stigmasterol (6) were isolated. The structures of the new coumarins were elucidated on the basis of chemical and physicochemical evidences.
