In vitro simulated digestion and fermentation characteristics of pumpkin polysaccharides and their effects on the human gut microbiota.

Although pumpkin polysaccharides have numerous health benefits, limited studies have investigated the impact of pumpkin polysaccharide digestion and fermentation characteristics on its biological activity. Herein, pumpkin polysaccharides (PPs) were subjected to simulated saliva-gastric-small intestinal digestion, followed by in vitro fermentation using healthy human faecal microbiota. Results indicate that PPs, acidic heteropolysaccharide with a molecular weight of 2.

Structural Characterization of Water-Soluble Pectin from the Fruit of and Its Protective Effects against DSS-Induced Colitis in Mice.

Polysaccharides from L. were investigated for their structural characterization and anti-inflammatory activity. Four low polymer dispersity index (PDI) subfractions were obtained: DRP-1 (153.

Comprehensive Profiling of Macamides and Fatty Acid Derivatives in Maca with Different Postharvest Drying Processes Using UPLC-QTOF-MS.

Macamides are characteristically found in maca ( Walper). Fatty acid derivatives are also an important type of constituent in maca, since they not only relate to the biosynthesis of macamides in the postharvest process but also possess some bioactivities. To study their comprehensive profiles in maca tubers processed via the air-drying method, ultraperformance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) analyses were performed to identify macamide and fatty acid molecules.
