“…The activity of gut microbiota was measured based on the activity of bacterial enzymes and the concentrations of SCFAs. Bacterial enzyme activity in the cecal digesta was determined spectrophotometrically based on the rate of p- or o-nitrophenol (PNP and ONP, respectively) release from their respective nitrophenylglucosides, according to the protocol described by Żary-Sikorska et al (2021) . The activity of the following microbial enzymes was assessed: α- and β-glucosidase, α- and β-galactosidase, β-glucuronidase, β-xylosidase, and α-arabinopyranosidase.…”

“…The following substrates were used: p-nitrophenyl-α-D-glucopyranoside (for α-glucosidase), p-nitrophenyl-β-D-glucopyranoside (for β-glucosidase), p-nitrophenyl-β-D-glucuronide (for β-glucuronidase), and p-nitrophenyl-β-D-xylopyranoside (for β-xylosidase). The p-nitrophenol concentration was quantified calorimetrically at 400 nm (details provided in Żary-Sikorska et al [ 34 ]). The enzymatic activity was expressed as micromoles of product formed per hour per gram of faeces.…”

The present study assessed the changes in faecal microbial activity in obese Wistar rats fed high-fat or low-fat diets supplemented with various forms of chromium (picolinate or nanoparticles). The 18-week study was divided into two phases: an introductory period (9 weeks; obesity status induction via a high-fat diet) and an experimental period (9 weeks; maintained on a high-fat diet or switched to a low-fat diet and Cr supplementation). During the experimental period (10–18 weeks of feeding), samples of fresh faeces were collected on chosen days. The bacterial enzymatic activity and short-chain fatty acids (SCFAs) concentration were assessed to characterise the dynamism of the changes in faecal microbial metabolic activity under the applied dietary treatments. The results indicated that faecal microbial metabolic activity displayed several adaptation mechanisms in response to modifications in dietary conditions, and a beneficial outcome resulted from a pro-healthy dietary habit change, that is, switching from a high-fat to a low-fat diet. Dietary supplementation with chromium nanoparticles further modulated the aforementioned microbial activity, i.e., diminished the extracellular and total enzymatic activities, while the effect of chromium picolinate addition was negligible. Both the high-fat diet and the addition of chromium nanoparticles reduced SCFA concentrations and increased the faecal pH values.

“…35 Besides that, anthocyanins' transport across the gastrointestinal barriers occurs in a time-and concentration-dependent manner. 21 Rather than being absorbed in the upper small intestine, the majority of anthocyanins pass to the colon, 36,37 where they are metabolized into a variety of low-molecular-weight catabolites by bacteria from the intestinal microbiota, with the main metabolic processes including the cleavage of glycoside bonds, hydrogenation, methylation, hydroxylation, and decomposition. 23,32,38 A human intervention study (healthy + ileostomy probands) has confirmed that the colon is a vital organ for absorbing biologically active ingredients including anthocyanins as well as their degradation derivatives.…”

Anthocyanins are phytonutrients with physiological activity belonging to the flavonoid family whose transport and absorption in the human body follow specific pathways. In the upper gastrointestinal tract, anthocyanins are rarely absorbed intact by active transporters, with most reaching the colon, where bacteria convert them into metabolites. There is mounting evidence that anthocyanins can be used for prevention and treatment of intestinal diseases, including inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), and colorectal cancer (CRC), through the protective function on the intestinal epithelial barrier, immunomodulation, antioxidants, and gut microbiota metabolism. Dietary anthocyanins are summarized in this comprehensive review with respect to their classification and structure as well as their absorption and transport mechanisms within the gastrointestinal tract. Additionally, the review delves into the role and mechanism of anthocyanins in treating common intestinal diseases. These insights will deepen our understanding of the potential benefits of natural anthocyanins for intestinal disorders.
