Abstract
This study investigated the effects of the sugarcane flavones diosmin, diosmetin, luteolin, and tricin, and their interactions with sugarcane fiber on the modulation of gut microbiota using in vitro batch fermentation. The alteration of fecal fermentation bacterial profile was analyzed using 16S rRNA sequencing data, while the bioavailability of fiber was indicated by short-chain fatty acid (SCFA) production and metabolism of polyphenols was measured directly by phenolic metabolites. Application of diosmin, diosmetin, luteolin, and tricin without fiber had no significant effect on the overall microbiota profile after 24 h of fermentation. When fiber alone was added, total SCFA production inc..
