However, safe and effective dietary interventions for salt-sensitive hypertension remain limited. Vine tea (Ampelopsis grossedentata), a traditional herbal tea widely consumed for centuries in southern China, has been reported to exhibit antioxidant, anti-inflammatory, and hepatoprotective activities, yet its antihypertensive efficacy and underlying mechanisms remain unclear. In this study, the chemical profile of vine tea aqueous extract (VTE) was characterized by UPLC\u2013Q\u2013TOF\u2013MS, identifying dihydromyricetin, isoquercitrin, and myricetin as the predominant flavonoids. The protective effects of VTE were evaluated in C57BL\/6J mice with high-salt-diet (HSD)-induced hypertension. VTE treatment significantly lowered systolic blood pressure and ameliorated cardiac and renal injury, accompanied by reduced inflammation, fibrosis, and cardiac stress-related gene expression. Gut microbiota analysis using 16S rRNA gene sequencing revealed that VTE restored microbial richness and diversity, enriching short-chain fatty acid-producing taxa while suppressing pathogenic Desulfovibrio and Ruminococcus torques. Untargeted plasma metabolomic profiling based on UPLC\u2013Q\u2013TOF\u2013MS further showed that VTE normalized tryptophan, bile acid, and glycerophospholipid metabolism, decreasing the uremic toxin indoxyl sulfate while increasing tauroursodeoxycholic acid. Notably, these protective effects were abolished under antibiotic-induced microbiota depletion, confirming that VTE acts through a gut microbiota-dependent mechanism. Collectively, VTE mitigates salt-induced hypertension and cardiorenal injury by remodeling the gut microbiota\u2013metabolite axis, supporting its potential as a natural dietary intervention for managing hypertension.<\/jats:p>","DOI":"10.3390\/ijms27020709","type":"journal-article","created":{"date-parts":[[2026,1,12]],"date-time":"2026-01-12T09:13:01Z","timestamp":1768209181000},"page":"709","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Vine Tea (Ampelopsis grossedentata) Extract Mitigates High-Salt-Diet-Induced Hypertension by Remodeling the Gut Microbiota\u2013Metabolite Axis in Mice"],"prefix":"10.3390","volume":"27","author":[{"given":"Yuxuan","family":"Gu","sequence":"first","affiliation":[{"name":"School of Basic Medical Sciences, Hubei University of Chinese Medicine, Wuhan 430065, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiling","family":"Li","sequence":"additional","affiliation":[{"name":"School of Basic Medical Sciences, Hubei University of Chinese Medicine, Wuhan 430065, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu","family":"Cao","sequence":"additional","affiliation":[{"name":"School of Basic Medical Sciences, Hubei University of Chinese Medicine, Wuhan 430065, China"},{"name":"Hubei Shizhen Laboratory, Wuhan 430065, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7194-0820","authenticated-orcid":false,"given":"Huabing","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Basic Medical Sciences, Hubei University of Chinese Medicine, Wuhan 430065, China"},{"name":"Hubei Shizhen Laboratory, Wuhan 430065, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"223","DOI":"10.1038\/s41581-019-0244-2","article-title":"The global epidemiology of hypertension","volume":"16","author":"Mills","year":"2020","journal-title":"Nat.
