Cancer chemopreventive activity and bioavailability of tea and tea polyphenols.
Consumption of tea (Camellia sinensis) has been associated with many health benefits including the prevention of cancer. Based on in vitro experiments, many mechanisms have been proposed to account for the cancer chemopreventive activity. The importance of some of these mechanisms in vivo remains in question due to an incomplete understanding of the bioavailability of the polyphenolic compounds...
متن کاملDetermination of tea components with antioxidant activity.
Levels of essential elements with antioxidant activity, as well as catechins, gallic acid, and caffeine levels, in a total of 45 samples of different teas commercialized in Spain have been evaluated. Chromium, manganese, selenium, and zinc were determined in the samples mineralized with HNO(3) and V(2)O(5), using ETAAS as the analytical technique. The reliability of the procedure was checked by...

متن کاملNeuroprotective effects of the green tea components theanine and catechins.
The neuroprotective effects of theanine and catechins contained in green tea are discussed. Although the death of cultured rat cortical neurons was induced by the application of glutamic acid, this neuronal death was suppressed with exposure to theanine. The death of hippocampal CA1 pyramidal neurons caused by transient forebrain ischemia in the gerbil was inhibited with the ventricular preadmi...
