Isolation and characterization of the compounds responsible for the antimutagenic activity of Combretum microphyllum (Combretaceae) leaf extracts
BACKGROUND Mutations play a major role in the pathogenesis and development of several chronic degenerative diseases including cancer. It follows, therefore that antimutagenic compound may inhibit the pathological process resulting from exposure to mutagens. Investigation of the antimutagenic potential of traditional medicinal plants and compounds isolated from plant extracts provides one of the...
متن کاملPreliminary phycochemical analysis and in vitro antibacterial screening of green micro algae, Desmococcus Olivaceous, Chlorococcum humicola and Chlorella vulgaris
Antibacterial activity of the Acetone, methanolic, ethanolic and DMSO extract of dried green microalgae Desmococcus olivaceous, chlorococcum humicola and chlorella vulgaris was assayed against five gram-ve (Klebsiella pneumoniae, Pseudomonas, Vibriocholerae, Streptococccus pyrogenes and Escherichia coli) and one gram +ve (Staphylococcus aureus) bacteria under culture conditions, using the agar ...
متن کاملGinseng extract exhibits antimutagenic activity against induced mutagenesis in various strains of Salmonella typhimurium.
Ginseng has been reported to exhibit antioxidant and antimutagenic activity. The present study was undertaken with a view to confirm whether the antioxidant activity of Ginseng is responsible for its antimutagenic action. The concentrated root extract of Panax ginseng (Ginseng extract I) and its lyophilized powder (Ginseng extract II) obtained from two different manufacturing houses, were teste...
متن کاملMutagenic potential of Indian tobacco products.
The mutagenic potential of aqueous extracts of masheri (ME), chewing tobacco alone (CTE) and a mixture of chewing tobacco plus lime (CTLE) was tested using the Ames assay. ME exhibited mutagenicity in Salmonella typhimurium TA98 upon metabolic activation with aroclor-1254-induced rat liver S9, while nitrosation rendered it mutagenic in TA100 and TA102. CTE exhibited borderline mutagenicity in t...
متن کاملSeparation of Salmonella Typhimurium Bacteria from Water Using MWCNTs Arrays
In this study, Salmonella Typhimurium bacteria removal from polluted water has been investigated using multiwall carbon nanotubes arrays. Experimental results reveal that the contact time, the bacterial concentration and the weight of multiwall carbon nanotubes arrays have positive significant effects on the bacteria removal efficiency. Increasing the contact time and the weight of multiwall ca...
