In this study, the changes of anthocyanin content, total phenols, antioxidant capacity, microbiota composition before and after digestion and intestine fermentation in stomach and intestine were studied. The results indicated that after simulated gastrointestinal digestion, compared with the original sample, the total phenol content and anthocyanin content of intestinal digestion group for 2 h (ID 2 group) decreased by 53.64% and 70.45%, respectively, DPPH inhibition rate was 32.75% and T-AOC values of the extracts decreased to 62.89U/mg. The anthocyanins were identified to be composed of cyanidin-3-arabinoside, cyanidin-3-galactoside, cyanidin-3-xyloside, and cyanidin-3-glucoside. Black Chokeberry (Aronia melanocarpa (Michx.) Elliot) anthocyanins significantly increased the relative richness of Bacteroides, promoted the growth of Bifidobacterium, Blautia, Faecalibacterium, and inhibited the growth of Prevotella, Megamonas, Escherichia/Shigella, etc. Anthocyanins have a positive regulatory effect on intestinal flora. These studies also provide essential information for the development of anthocyanin related health care products and drug products.
