Chen L, Li X, Gu Q. Chimonanthus salicifolius extract alleviates DSS-induced colitis and regulates gut microbiota in mice. Food Sci Nutr 2023; 11:3019-3030.

Abstract
Ulcerative colitis is a chronic and recurrent gastrointestinal intestinal disease accompanied by inflammatory disorders, immunologic inadequacy, and intestinal flora dysbiosis, and current therapeutic pharmaceuticals have limited side effects. In this study, we revealed the extraction method of Chimonanthus salicifolius, analyzed the main component, compared the effect of its extract, Lactobacillus, and conventional drugs with different properties on DSS (dextran sodium sulfate)-induced colitis, and indicated extract regulatory properties of inestinal flora. A colitis model was established on experimental design, and BALB/c mice (male, 7 weeks old) were randomly assigned to five groups (n = 10): control, DSS model, Chimonanthus salicifolius extract (CSE), Lactobacillus rhamnosus GG (LGG), and 5-aminosalicylic acid (5-ASA) groups. The three treatments could alleviate the symptoms and remit inflammation induced by DSS, in which CSE and LGG groups could both decrease the proinflammatory cytokine IL-6, IL-8, and TNF-α levels and increase anti-inflammatory cytokines IL-10 and TGF-β. The CSE intervention significantly promoted the higher production of butyric acid than LGG and 5-ASA groups (p < .05) after DSS challenge. Analysis of intestinal flora showed that CSE administration remarkably decreased the relative abundance of pathogenic bacteria Heliobacteriaceae and Peptococcaceae and exhibited higher abundance of Lactobacillaceae and Bifidobacterium than LGG in intestinal tract of mice (p < .05). These findings indicated that Chimonanthus salicifolius extract may have been beneficial for preventing and treating colitis.

Metabolic profiling of Chimonanthus grammatus via UHPLC-HRMS-MS with computer-assisted structure elucidation and its antimicrobial activity. FRONTIERS IN PLANT SCIENCE 2023; 14:1138913. [PMID: 37229132 PMCID: PMC10205022 DOI: 10.3389/fpls.2023.1138913] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Accepted: 03/27/2023] [Indexed: 05/27/2023]
Abstract
Chimonanthus grammatus is used as Hakka traditional herb to treat cold, flu, etc. So far, the phytochemistry and antimicrobial compounds have not been well investigated. In this study, the orbitrap-ion trap MS was used to characterize its metabolites, combined with a computer-assisted structure elucidation method, and the antimicrobial activities were assessed by a broth dilution method against 21 human pathogens, as well as the bioassay-guided purification work to clarify its main antimicrobial compounds. A total of 83 compounds were identified with their fragmentation patterns, including terpenoids, coumarins, flavonoids, organic acids, alkaloids, and others. The plant extracts can strongly inhibit the growth of three Gram-positive and four Gram-negative bacteria, and nine active compounds were bioassay-guided isolated, including homalomenol C, jasmonic acid, isofraxidin, quercitrin, stigmasta-7,22-diene-3β,5α,6α-triol, quercetin, 4-hydroxy-1,10-secocadin-5-ene-1,10-dione, kaempferol, and E-4-(4,8-dimethylnona-3,7-dienyl)furan-2(5H)-one. Among them, isofraxidin, kaempferol, and quercitrin showed significant activity against planktonic Staphylococcus aureus (IC50 = 13.51, 18.08 and 15.86 µg/ml). Moreover, their antibiofilm activities of S. aureus (BIC50 = 15.43, 17.31, 18.86 µg/ml; BEC50 = 45.86, ≥62.50, and 57.62 µg/ml) are higher than ciprofloxacin. The results demonstrated that the isolated antimicrobial compounds played the key role of this herb in combating microbes and provided benefits for its development and quality control, and the computer-assisted structure elucidation method was a powerful tool for chemical analysis, especially for distinguishing isomers with similar structures, which can be used for other complex samples.
