Tea infusions are consumed frequently and in large amounts, so they may play a role in modelling intestinal microflora or in preventing bacterial diseases. The present study examined the effect of different kinds of tea (black, green and puerh) on Lactobacillus rhamnosus, Lactobacillus plantarum, Leuconostoc mesenteroides subsp. mesenteroides, Escherichia coli, Staphylococcus aureus and Salmonella...
Extracts of dried leaves of dill (Anethum graveolens) and parsley (Petroselinum crispum), black pepper fruits (Piper nigrum), and black cumin seeds (Nigella sativa) under and after simulated digestion were investigated for their antiradical activity, iron chelation, iron reduction and inhibition of lipid peroxidation. The changes of total phenolic compounds, phenolic acids, quercetin and kaempferol...
Roasted sesame seeds, pumpkin seeds, sunflower seeds, soy beans, and wheat germs were obtained from Ekoprodukt company (Częstochowa, Poland). Phenolic compounds were extracted with 80% aqueous methanol. The extract of roasted sunflower seeds was characterised by a higher content of total phenolics (158 mg/g). The Total Antioxidant Capacity was the highest in the extract of roasted sunflower seeds...
This paper applies our recently acquired knowledge of the large and systematic changes in internal reducing power to controlled changes in the cell's primary electron-donor and -acceptor substrates. The systematic cellular responses of the NADH/NAD ratio is incorporated into kinetic equations for reductive dehalogenation and oxygenation reactions. Results show that the external donor and acceptor...
