Characterization of sea buckthorn polysaccharides and the analysis of its regulatory effect on the gut microbiota imbalance induced by cefixime in mice

The Experimental Development of Bread with Enriched Nutritional Properties Using Organic Sea Buckthorn Pomace

“…Sea buckthorn (Hippophae rhamnoides L.) belongs to the Elaeagnaceae family. It is a deciduous shrub that is widely found in Northwestern Europe and Asia and is distributed from the coastal regions to the mountains [9]. Its use and processing gained more and more attention recently due to its nutritional properties and health benefits; it is rich in ascorbic acid, carotenoids, tannins, tocopherols, fatty acids, and flavonoids and improves blood circulation, relieving irritability.…”

“…Its use and processing gained more and more attention recently due to its nutritional properties and health benefits; it is rich in ascorbic acid, carotenoids, tannins, tocopherols, fatty acids, and flavonoids and improves blood circulation, relieving irritability. It is a good immunity enhancer, protecting the cardiovascular system, resisting oxidation, and presenting great antimicrobial properties [9][10][11]. Sea buckthorn berries can be consumed in their natural state or be processed into juice, with the latter resulting in a significant amount of pomace.…”

In Vitro Digestion and Fecal Fermentation of Polysaccharides from Physalis alkekengi and its Impacts on Human Gut Microbiota

“…The puri ed polysaccharides produced the highest levels of bene cial SCFAs. Xie et al identi ed seven different SCFAs in the feces of mice, with the highest levels of acetate, propionate, and butyrate [39]. Acetic acid and lactic acid are the main end products of Bi dobacterium and lactic acid bacteria fermentation, which have been demonstrated to suppress appetite.…”

“…The intake of bioactive polysaccharides alters the metabolites and composition of the gut ora, particularly the enhancement of SCFAs and the promotion of a healthy gut ora [34][35]. Wu et al showed that Physalis alkekengi L polysaccharides can regulate intestinal ora and increase microbial metabolites to prevent age-induced insulin resistance [39]. In this experiment, an in vitro digestion model was established to simulate salivary-intestinal digestion and large intestine fermentation, and the degree of digestion absorption and fermentation of Physalis alkekengi polysaccharides was measured.…”

Medicinal and edible polysaccharides from ancient plants: extraction, isolation, purification, structure, biological activity and market trends of sea buckthorn polysaccharides

“…75 Xie et al found that SPs could improve the cefixime-induced gut microbiota imbalance, which may be due to increasing the relative abundance of Verrucomicrobia , Actinobacteriota , Akkermansia , Faecalibaculum , and Allobaculum , reducing Epsilonbacteraeota and Helicobacter abundance, and increasing the concentration of SCFAs. 44 Lan et al demonstrated that SPs significantly inhibited the elevation of the Firmicutes/Bacteroidetes ratio, reduced the abundance of Lactobacillus , Dubosiella , Bilophila , and Streptococcus , increased the abundance of Bifidobacterium , Rikenellaceae_RC9_gut_group , Alistipes as well as Bacteroides , and the production of microbial metabolites SCFAS in HFD-induced obese mice. 34 Moreover, Liu et al found that SPs, Astragalus polysaccharide (APS), and SPs combined with APS treatment could improve the diversity, relative abundance, and community structure of the gut microbiota in mice with alcoholic fatty liver disease.…”
