Significant changes in metabolite profile and tyrosine, phenyl alanine and tryptophan biosynthesis. ( Kwandee et al, 2023 ) | Hawthorn (Crataegus pinnatifida) | Procyanidin | Not analysed | In vivo administration | Mice model | Upragulate growth of Akkermansia, Bacteroides and Adlercreutzia, and decreased Lactobacillus, Bifidobacterium, Blautia, Lachnospiraceae and Subdoligranulum Reduced insulin resistance, oxidative stress | ( Han et al, 2022 ) |
peanut skin | Type A procyanidins | Not tested | In vivo administration | Balb/c mice model | Reverse the ulcerative colitis by improving gut barrier and modu;ating inflammatory cytokines Increase growth of Oscillibacter and Roseburia Decrease growth of Bacteroides , Helicobacter , Parabacteroides , Escherichia-Shigella , and Enterobacter | ( Huang et al, 2022 ) |
Grape seed extract | Proanthocyanidin polyphenol extract | Not tested | In vivo administration | Mice model | GSPE normalized the colonic Firmicutes/Bacteroidetes ratios, reversed the relative abundance of Weissella, Faecalibaculum, Bacteroides, Akkermansia and Ruminococcus 1 induced by HFD reduced HFD-induced insulin resistance and increased levels of adiponectin and leptin | ( Du et al, 2021 ) |
Pomegranate juice | Hydrolysable tannin | Not mentioned | In vivo fermentation | Insulin resistance mice model | Reduced glucose and lipid metabolic disorder, liver injury and insulin resistance; decreased the Firmicutes/Bacteroides ratio, reduced Coprococcus and Anaerotruncus, and increased Rikenellaceae and liver tumor necrosis factor-alpha and interleukin-1β levels, supressed liver IKKβ and NF-κB phosphorylation; and upragulated liver autophagy-related proteins LC3-II, P 62, and Beclin1. | ( Cao et al, 2021 ) |
Quebracho wood extract Chestnut wood extract\ Tara pods extract | profisetinidin condensed tannin hydrolysable ellagitannins hydrolysable gallotannins) | Not tested | In vitro digestion and fermentation | Human gut microbiata | Increase of genus Akkermansia , Lachnospiraceae and Ruminococcaceae sp. |
