potamogeton perfoliatus/salmonella infections

The mechanism of antimutagenicity of water extracts of grass-wrack pondweed (Potamogeton oxyphylus Miquel), curled pondweed (Potamogeton crispus L.) and smartweed (Polygonum hydropiper L.) towards benzo[a]pyrene mutagenicity in Salmonella typhimurium was investigated. The antimutagenic components in

It was found that the water extract of grass-wrack pondweed (Potamogeton oxyphylus Miquel) had inhibitory activity for reverse mutations induced by benzo[a]pyrene, 2-aminoanthracene and 2-nitrofluorene with Salmonella typhimurium TA100 and TA98. The active substance was heat-resistant, and the

The antimicrobial activities of aqueous and organic solvents (chloroform, ethanol and methanol) extracts of four plants Ceratophyllum demersum L., Eichhornia crassipes, Potamogeton crispus and Potamogeton pectinatus were tested in vitro against seventeen different microorganisms including
