The antimutagenic properties of soluble instant teas were examined using the bacterial Ames assay. Inhibition of the numbers of revertants induced from a number of known mutagens indicates that aqueous extracts of instant teas have antimutagenic activity and antioxidative properties, and can inhibit nitrosation reactions. Despite a significant reduction in the amounts of major green tea catechi...

in Korea, is a mushroom belonging to the Hymenochaetaceae basidiomycetes and also found mainly in tropical America, Africa and Asian countries. Overall, PL was reported to be a medicinal mushroom with anti-tumor activity, protective effect on liver damage, immunomodulatory action, antiangiogenic and antioxidant activity. The hot aqueous extract of PL inhibited the growth of sarcoma 180 to about...

Polyphenolic compounds present in rosemary were found to have antioxidant properties, anticarcinogenic activity, and to increase the detoxification of pro-carcinogens. The aim of the study was to determine the effect the aqueous extract of rosemary (AER) on mutagenicity induced by methylmethane sulfonate in meristematic cells of Allium cepa, as well as to describe its mode of action. Anti-mutag...

Selenium can have cancer chemopreventive activity, although the mechanism of action has not been well defined. Selenazolidine-4-(R)-carboxylic acids (SCAs) were devised as prodrugs of L-selenocysteine, to provide selenium in a form and at a concentration commensurate with cancer chemopreventive activity. In the present study, a series of selenazolidines has been evaluated in the Salmonella typh...

Exopolysaccharides are high molecular weight polymers of repeated sugar units with diverse chemical structure and unique properties produced by microorganisms. Lactic acid bacteria important exopolysaccharide producers. derived exopolysaccharides, one the postbiotics, known to have technological such as stabilizing, thickening, emulsifing also biological activities. can synthesis exopolysacchar...
