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 detection of natural compounds active against C. pneumoniae is presented as an example and can be guided by epidemiologic studies facilitated with computer assisted HPLC microfractionation and microplate technology.

TL;DR: Results show that negative ion IS with an eluent system consisting of acidic ammonium acetate buffer provides the best conditions for detection of flavonoids in mass spectrometry mode, their LODs being between 0.8 and 13 microM for an injection volume of 20 microl.

TL;DR: Oligomeric procyanidins were isolated from the leaves and flowers of hawthorn for the first time, in addition to known procyAnidins including dimers B-2, B-4 and B-5, trimers C-1 and epicatechin-(4 beta-->6)-epicateschin-( 4 beta-->8)-epicatechin, and tetramer D-1.
