Metabolic profiling, genomic, Polyphenols and metabolism, and Polyphenolw approaches were applied to map eight selected polyphenols' metabolism with gut bacteria and their genes.
First, in the metallic profiling study, we aimed to characterize gut microbiota-mediated biotransformation of eight selected polyphenols, namely curcumin, avicularin, resveratrol, dihydro-resveratrol, nobiletin, 3ˈ-demethylnobiletin, and 4ˈ-demethylnobiletin. First, anaerobic fermentation experiments were conducted using strains of human fecal bacteria.
Next, cell-free supernatants were profiled for targeted metabolites using HPLC and LC-MS. At the same time, bacteria growth was evaluated. For the first time, we identified three bacterial strains that were capable of metabolizing curcumin by hydrogenation and cleavage reaction.
These reactions have substrate specificity, they cannot hydrogenase resveratrol. We also discovered de-glucuronidation of avicularin by one bacterial strain that was isolated from a healthy volunteer.
There were no substantial effects of these polyphenols on the growth of genera morphology of the bacteria.
Next, to further identify the genomic basis of different microbial metabolic profiling, de novo genome assembly and comparative genomic analysis were conducted. After we sequenced the whole genome of each bacterium using Illumina NovoSeq platform, genome assembly, taxonomic classification, phylogenetic analysis, comparative genomic analysis, and enzyme protein homology detection were performed to identify the unique genes that were potentially involved in curcumin and avicularin metabolism.
The whole-genome data provide a foundation to the survey of the transcriptomic landscape, global transcriptomics study of Lactobacillus gasseri and Ligilactobacillus salivarius in response to curcumin treatment were conducted.
Curcumin generally shifted their transcriptomes compared with not curcumin treatment vehicle controls. The global transcriptome links the expression of putative curcumin degradation genes and networks and metabolic phenotypes.
Overall, we use a combination of metabolic, genetics, and transcriptomic profiling to identify and characterize gut symbionts Lactobacillus gasseri, and Ligilactobacillus salivariusand Bifidobacterium infantis that generated bioactive curcumin-metabolites.
One bacterial strain that was isolated from a healthy person can metabolize avicularin. These results emphasized the importance of gut microbial genomes the in biotransformation of food components and their impact on human health.
These results emphasized the importance of gut microbial biotransformation of food components and its impact on human health. Doctoral Dissertations.

Therefore, intervention does not only involve exploring clinical therapeutic treatment at the point of diagnosis, but it is also crucial to prevent the occurrence of metabolic syndrome and its complications by keeping a healthy lifestyle, such as by doing sports or by adding vegetables, low sugar fruit, and less salt to the diet.
Natural polyphenols, common specialized metabolites from plants, are a class of bioactive compounds widely found in fruits, vegetables, tea, and herbal medicines. They confer potentially beneficial activity, by regulating gut microbiota and enacting anti-inflammation or antioxidation 4 — 6.
A diet rich in polyphenols alleviates the symptoms and risk factors of metabolic syndrome, such as by reducing blood pressure, improving insulin-resistance and modulating lipid metabolism 7 , 8.
Traditional plants are often used as a source of functional food or pharmaceutical in the industry because they are a rich source of bioactive compounds. For example, sea buckthorn, a hardy deciduous shrub distributed especially in southwest, northeast, and northwest of China, contains a high yield of polyphenols in its leaves and fruit.
The phytochemical components of three teas made from sea buckthorn leaves with different processing treatment were studied by high-performance liquid chromatography HPLC , creating a chemophenetic fingerprint that was studied by multivariate statistical analysis Wang et al. A total of 48 compounds were identified, including four phenolic acids, 11 tannic acids, and 27 flavonoids.
Due to the high yield and diversity of polyphenols, the sea buckthorn tea demonstrated inhibition of α-glucosidase activity and also conferred antioxidant effects in vitro Wang et al. Oolong tea, another traditional Chinese tea made from partially fermented Camellia sinensis leaves, is especially popular in south China, and has also been proven to have potential health benefits.
Li et al. Oolong tea also regulated the expression of genes related to lipid metabolism and inflammation. To explore the biological effects of polyphenols further, a review by Chen et al. systematically reviewed the literature and commented on the potential network interaction mechanism of natural polyphenols in Chinese herbal medicine.
The authors focused on the effects of metabolic homeostasis, immunity, and gut microbial regulation on obesity and diabetes. Indeed, metabolic disorders are strongly linked to immune imbalance, which may lead to chronic systemic inflammation. When pro-inflammatory cytokines are produced by immune cells it disrupts the metabolism of lipids and glucose, leading to insulin-resistance.
Disturbance to gut microbiota increases gut permeability leaky gut , leading to the entry of microbiota or endotoxic substances into intestinal tissues and systemic circulation.
Ordinarily the metabolites of gut microbiota play an important role in regulation of immunometabolism Chen et al. The profile of natural polyphenols and their yield in biota is affected by postharvest treatment and processing technology. Wei et al. revealed that 0. Moreover, different processing treatment of sea buckthorn leaves were examined phytochemically, including fresh leaves, black tea produced by withering, rolling, fermentation and drying, and green tea produced by rolling, screening and drying process.
Significant differences of polyphenol patterns occurred among the different processing tea Wang et al. The fermentation process makes the polyphenols susceptible to oxidation by enzymes, allowing catechins to be converted into theaflavins and thearubins, which confer the black tea fragrance and color.
In summary, the above-mentioned results demonstrate a valuable aspect to the composition, characterization, and bioactivities of natural polyphenols from fruit and traditional plants, in the context of preventing or controlling metabolic syndrome-associated diseases, especially obesity and diabetes.
Polyphenols have a wide range of benefits and pharmacological effects. This reiterates that they serve as promising nutraceuticals or pharmaceuticals in health and food industries. Despite the evidence that has accumulated in relation to this important Research Topic, there are still many aspects that need to be clarified and improved.
For example, low bioavailability of many polyphenols limits their application on food industry or the clinic. There are key techniques that may improve their bioavailability, such as formation of micelles, nanoparticles, liposomes, and phospholipid complexes.
Converting polyphenols into ingredients that can be easily utilized through gut microbiota could be another way to promote the utilization of polyphenols Chen et al. All authors listed have made a substantial, direct, and intellectual contribution to the work and approved it for publication.
