Abstract
Obesity has emerged as a global health issue with its prevalence continuously increasing and being associated with multiple comorbidities. Although existing medications are effective, they often come with significant side effects, making dietary therapy an advantageous alternative. Hawthorn leaves and their active component, vitexin, have shown potential in regulating lipid metabolism and improving gut microbiota imbalance. This study utilized a high-fat diet-induced obese mouse model, administering different doses of hawthorn leaves and vitexin for 13 weeks, and employed 16S rRNA sequencing and metabolomics to analyze the composition of gut microbiota and metabolites. The results demonstrated that hawthorn leaves and vitexin significantly slowed body weight gain, improved glucose tolerance, regulated blood lipid levels, and downregulated the expression of obesity-related gene in mice (). Additionally, the treatment groups showed a significant improvement in gut microbiota diversity. Both vitexin and hawthorn leaves increased the abundance of,,(which belong to the Bacillota phylum) and(Actinobacteria phylum), while reducing the abundance of(Bacillota phylum). Moreover, the hawthorn leaves and vitexin treatments may alleviate obesity-related symptoms by increasing the fecal content of testosterone propionate, formoterol, and isoleucyl-prolyl-proline, and decreasing the content of Trolox. These findings highlight the potential of hawthorn leaves and vitexin as functional foods for obesity management by modulating gut microbiota pathways, offering a promising dietary therapy approach.
