In order to investigate new metabolites which are only induced in a plant callus infected by a pathogenic fungus, dual cultures with combinations of 10 species of fungi and 6 plant cell lines from different species were established. Among the combinations tested, the methanolic extract of a dual culture consisting of a plant cell line, Phytolacca americana and a fungus, Botrytis fabae showed a ...

conclusions the alcoholic extract of p. harmala was very effective against the selected esbl-producing e. coli isolates harboring the tem gene. therefore, it could be suggested as an antibacterial agent in the future. more researches are necessary for detecting the mechanism of this plant’s behavior and its pharmacological effects. results results of this study showed that in disk diffusion met...

.co m) . was displayed by Terminalia chebula seed extract against B. cereus. In fact, this plant extract (both aqueous and ethanolic) could inhibit all the bacterial strains investigated. Out of 50 aqueous extracts, 16 extracts showed activity against any one of grampositive bacteria, while only 10 extracts showed activity against any one of gram-negative bacteria. The plant extracts inhibited ...

salvia verticillata is one of the salvia species which possesses remarkable antioxidant activity. in the present study, we investigated the possible effects of hydro-alcoholic extract from salvia verticillata plant (sve) in various models of anxiety, depression and seizure in mice. mice were randomly divided into control (saline), sve-treated and standard treatment groups. the sve-treated group...

BACKGROUND Aging is an inevitable process for all living organisms. During this process reactive oxygen species generation is increased which leads to the activation of hyaluronidase, collagenase and elastase, which can further contribute to skin aging. Four southern African medicinal plants; Clerodendrum glabrum, Schotia brachypetala, Psychotria capensis and Peltophorum africanum, were investi...
