Urolithins: a Comprehensive Update on their Metabolism, Bioactivity, and Associated Gut Microbiota

open access: yesMolecular Nutrition &Food Research, Volume 66, Issue 21, November 2022., 2022
About 20 years ago, urolithins are discovered as bioavailable metabolites produced by the human gut microbiota from ellagitannins and ellagic acid. Pioneering investigations suggested pleiotropic effects for urolithins that growing evidence confirms, especially for urolithin A.

New approaches to tannin analysis of leaves can be used to explain in vitro biological activities associated with herbivore defence

open access: yesNew Phytologist, Volume 225, Issue 1, Page 488-498, January 2020., 2020
Summary Although tannins have been an important focus of studies of plant–animal interactions, traditional tannin analyses cannot differentiate between the diversity of structures present in plants. This has limited our understanding of how different mixtures of these widespread secondary metabolites contribute to variation in biological activity.
