Antimicrobial properties of phenolic compounds from berries

Riitta Puupponen-Pimiä, +6 more
- 01 Apr 2001 - 
TL;DR: To investigate the antimicrobial properties of phenolic compounds present in Finnish berries against probiotic bacteria and other intestinal bacteria, including pathogenic species.
Journal ArticleDOI

Tannins: current knowledge of food sources, intake, bioavailability and biological effects.

José C. E. Serrano, +4 more
- 01 Sep 2009 -

Comparison of antioxidant activities of onion and garlic extracts by inhibition of lipid peroxidation and radical scavenging activity

Anna Maria Nuutila, +3 more
- 01 Jun 2003 - 
TL;DR: In this paper, the antioxidant properties of methanol extracts of selected varieties and parts of garlic and onion were determined by two methods: inhibition of lipid peroxidation induced by tert-butyl hydroperoxide in isolated rat hepatocytes and scavenging activity against diphenylpicrylhydrazyl radical.
Journal ArticleDOI

Berry Phenolics: Antimicrobial Properties and Mechanisms of Action Against Severe Human Pathogens

Liisa Nohynek, +6 more
- 01 Jan 2006 - 
TL;DR: The most sensitive bacteria on berry phenolics were Helicobacter pylori and Bacillus cereus and Campylobacter jejuni and Candida albicans were inhibited only with phenolic extracts of cloudberry, raspberry, and strawberry, which all were rich in ellagitannins.
Journal ArticleDOI

Berry phenolics selectively inhibit the growth of intestinal pathogens.

Riitta Puupponen-Pimiä, +6 more
- 01 Apr 2005 -
