TL;DR: High activities were found in tree materials, especially in willow bark, spruce needles, pine bark and cork, and birch phloem, and in some medicinal plants including heather, bog-rosemary, willow herb, and meadowsweet and potato peel and beetroot peel extracts showed strong antioxidant effects.

TL;DR: Flavone, quercetin and naringenin were effective in inhibiting the growth of the organisms and purple loosestrife was the most active plant extracts against gram-positive Staphylococcus aureus.

TL;DR: The extraction method affected remarkably both the phenolic composition and the antioxidant activity, but with statistical analysis the observed activity could not be well explained with the contents of individual phenolic subgroups.

TL;DR: To investigate the antimicrobial properties of phenolic compounds present in Finnish berries against probiotic bacteria and other intestinal bacteria, including pathogenic species.

TL;DR: The effects and mechanisms of naturally occurring phenolic compounds on iNOS expression and NO production in activated macrophages partially explain the pharmacological efficacy of flavonoids as anti-inflammatory compounds.
