In the present study, the anti-lipoperoxidant activity of some phenolic acids, flavonoids and purified tannins from Quercus sp. was determined. Phenolic acids (10, 25 and 50 µg/ ml) inhibited lipid peroxidation by 42 – 51%. Caffeic acid seems to be the most potent inhibitor among phenolic acids. Tannic acid, a commercially available tannin, inhibited lipid(More)
In the present work, five hundred and sixty-seven isolates of lactic acid bacteria were recovered from raw bee pollen grains. All isolates were screened for their antagonistic activity against both Gram-positive and Gram-negative pathogenic bacteria. Neutralized supernatants of 54 lactic acid bacteria (LAB) cultures from 216 active isolates inhibited the(More)

The antioxidative activities of subfractions; methanol (CE), chloroform (CHE) and ethyl acetate (EAE) of Teucrium polium extracts (TPE) were investigated. HPLC analysis of the plant revealed the existence of procyanidins B 1 and B 2 , gallic acid, catechin and epicatechin. All the extracts showed inhibitory properties on xanthine oxidase, with IC 50 ranging(More)
