The use of natural compounds from plants can provide an alternative approach against food-borne pathogens. The mechanisms of action of most plant extracts with antimicrobial activity have been poorly studied. In this work, changes in membrane integrity, membrane potential, internal pH (pH(in)), and ATP synthesis were measured in Vibrio cholerae cells after exposure to extracts of edible and med...

BACKGROUND Urtica dioica, Taraxacum officinale, Calea integrifolia and Caesalpinia pulcherrima are widely used all over the world for treatment of different illnesses. In Mexico, these plants are traditionally used to alleviate or counteract rheumatism and inflammatory muscle diseases. In the present study we evaluated the activity of aqueous and methanolic extracts of these four plants, on the...

Chloroform, methanol, aqueous and ethanolic extracts of the stem bark of Saraca indica were investigated for their antibacterial and antifungal activity against standard strains of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Bacillus cereus, Klebsiella pneumoniae, Proteus mirabilis, Salmonella typhimurium and Streptococcus pneumoniae and the fungi: Candida albicans and Cryp...

present study reports analgesic activity of petroleum ether, chloroform, ethyl acetate and methanolic extracts of leaves and seeds of trigonella foenum-graecum linn. (fabaceae) using hot plate method for evaluation of central analgesic activity and acetic acid induced writhing test for evaluation of peripheral analgesic activity in mice.   all the extracts of trigonella foenum-graecum showed si...

Methanolic and chloroform-methanol extracts of 25 identified species of marine fauna have been screened for a wide range of biological activities. Of these, 2 extracts exhibited diuretic activity, while antibacterial, antiviral, oxytocic and spasmolytic activities, were observed in 1 extract each.

Methods The HIV inhibitory activity of aqueous and methanolic extracts of S. swartzii was determined on laboratory adapted strains of HIV-1 clades C and A by indirectly measuring reduction in HIV-1 gag p24 antigen levels and inhibition of HIV-1 RT activity in supernatants of virus infected donor peripheral blood mononuclear cell (PBMC) cultures grown in varying concentrations of the extracts. P...

In view of alleged antidiabetic potential, effect of the petroleum ether, methanol, and aqueous extracts of Terminalia catappa Linn (combretaceae) fruit, on fasting blood sugar levels and serum biochemical analysis in alloxan-induced diabetic rats were investigated. All the three extracts of Terminalia catappa produced a significant antidiabetic activity at dose levels 1/5 of their lethal doses...

The present investigation was carried out to determine the antioxidant properties in methanolic extract of leaves, stem, fruit and roots of Physalis angulata (L). The antioxidant assay was carried out using free radicals DPPH, superoxide, nitric oxide, hydrogen peroxide and hydroxyl radical. Among the extracts tested fruit and leaf extracts were found to be significant in their antioxidant prop...

Rosa canina L. is a member of Rosaceae family, which is well-known for its high phenolic contents. These compounds are known to possess antioxidant and antiradical effects. In order to compare the antioxidant and antiradical activity of wild Rosa phenolic extracts, two wild Rosa species (Rosa canina L. and Rosa pimpinellifolia L.) were selected from Takab, Oshnavieh and Qasemloo Valley of Urmia...

this study was conducted to evaluate the cytoprotection of various extracts and bioactive compounds found in pistacia vera againts cytotoxicity, ros formation, lipid peroxidation, protein carbonylation , mitochondrial and lysosomal membrane damages in cell toxicity models of diabetes related carbonyl (glyoxal) and oxidative stress (hydroperoxide). methanol, water and ethyl acetate were used to ...
