TL;DR: In this paper, the authors used a well-known antioxidant, oleuropein, as a reference compound to investigate the antioxidant activity of oleacein for an array of reactive oxygen (superoxide anion, O 2 - ; hydrogen peroxide, H2O2; hypochlorous acid, HOCl) and nitrogen species (nitric oxide, NO; peroxynitrite, ONOO−) formation.

TL;DR: The present study aimed at comparing the anti-inflammatory and antioxidant activity of extracts of the three most popular Epilobium species and juxtaposing this activity against the dominating compounds from the following extracts: oenothein B (OeB), quercetin-3-O-glucuronide and myricetin

TL;DR: The anti-inflammatory effects of urolithins at concentrations that are physiologically relevant for gut tissues (≥40 μM), as revealed in this study, support the data from in vivo studies showing the beneficial effects of ellagitannin-rich products toward intestinal inflammation.

TL;DR: The data obtained clearly indicate that in the case of peroral use of the examined ellagitannin-rich plant materials the bioactivity of gut microbiota metabolites, i.e. urolithins, has to be taken under consideration.

TL;DR: Oleacein and oleuropein restored migration, adhesion and tube formation of EPCs diminished by angiotensin II in a concentration-dependent manner and were related to NF-E2-related factor 2 (Nrf2) transcription factor activation and the increase of heme oxygenase-1 (HO-1) expression.
