Purple red rice anthocyanins alleviate intestinal damage in cyclophosphamide-induced mice associated with modulation of intestinal barrier function and gut microbiota

•Purple red rice bran anthocyanins (PRBA) improved intestinal morphology.•PRBA restored the levels of cytokines, endotoxin and lipopolysaccharide binding protein.•PRBA upregulated the expression of tight junction proteins and NF-κB signaling pathway.•PRBA promoted the production of SCFAs and regulated the composition of gut microbiota.
