Summary of "Differential catabolism of an anthocyanin-rich elderberry extract by three gut microbiota bacterial species."

Elderberries are good sources of anthocyanins, which are poorly absorbed in the upper gastrointestinal tract but extensively transformed into phenolic metabolites at colonic level. Since different gut microbiota strains have different metabolism, the catabolism of anthocyanins may lead to inter-individual differences in metabolite production. In this work, an anthocyanin-rich elderberry extract was incubated with three single gut microbial strains (Enterobacter cancerogenous, Bifidobacterium dentium and Dorea longicatena) up to four days, to assess differences in their phenolic metabolism. All the strains degraded the elderberry anthocyanins, but the metabolic pathways followed were different. Although some metabolites were common for all the strains, a wide disparity was observed in the kind and in the amount of several phenolic metabolites produced by each species. These in vitro preliminary results may be of help in the interpretation of the bioavailability of anthocyanins and give a clue to understand inter-individual variability in metabolite production.
