Abstract

Background: Diabetes mellitus is a chronic metabolic disorder posing a significant public health challenge. Dendrobium officinale is a valuable edible-medicinal homologous plant. Phenolic extracts from fermented D. officinale leaves (DOLP) demonstrate a hypoglycemic effect. However, the effects of DOLP on physiological metabolism and gut microbiota under diabetic conditions remain unknown.

Results: Untargeted metabolomics analysis revealed that DOLP reversed 98 significantly differential metabolites (SDMs) in diabetic mice. Indoxyl sulfate and palmitoyl sphingomyelin were identified as the primary candidate biomarkers associated with the hypoglycemic effect. KEGG pathway enrichment analysis underscored the significance of arginine and proline metabolism, ascorbate and aldarate metabolism, and fatty acid metabolism in the regulatory effects of DOLP. Furthermore, DOLP reversed the dysbiosis of the gut microbiota in diabetic mice, significantly influencing the relative abundance of the genera Intestinimonas, GCA_900066575, Muribaculum, and Enterorhabdus. These differential genera exhibited various correlations with SDMs, including l-hydroxyarginine, γ-guanidinobutyrate, l-threonate, d-galactarate, l-ascorbic acid, palmitic acid, cis-9-palmitoleic acid, octadecanoic acid, and oleic acid.

Conclusion: The protective effect of DOLP against diabetes mellitus is closely linked to its regulation of physiological metabolism and gut microbiota. DOLP may serve as a promising agent for the prevention and treatment of diabetes mellitus. © 2025 Society of Chemical Industry.

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
