air pollutants are reported to increase the specific ige response to allergens. to study allergen proteins and determine the effect of air pollutants on the allergenic potential of pollen extracts, the extracts were injected intraperitoneally and subcutaneously in guinea pigs. the results were analyzed by skin prick test (spt), elisa and sds-page followed by immunoblotting. the pollen extract o...

extracts derived from viscum album have been shown to kill cancer cells in vitro. some studies have noted that different species of this plant collected from around the world displayed cytotoxic effects in different extents. in the present study, we evaluated the effects of iranian mistletoe extracts on five cancer cell lines. plants growing on hornbeam tree (carpinus betulus) were collected, a...

objectives this study explored the qualitative and quantitative antibacterial potential of c. intybus. further qualitative analysis of phytochemical content was performed. methods cichorium intybus seed extracts were prepared in aqueous, chloroform, ethanol, and hexane separately. results all the extracts of c. intybus seeds were screened for antibacterial activity and phytochemical content. ci...

background and objectives: the aerial part extracts of eremostachys macrophylla  from labiatae family, which has been traditionally used in wound healing, snake bites, rheumatism and joint pains, were investigated for general toxicity, anti-proliferative, free radical scavenging and anti-bacterial effects.moreover, preliminary phytochemical investigations were carried out on the extracts. metho...

Three extracts of Pulicaria dysenterica were examined for antibacterial activity using the agar disk-diffusion method against six bacterial strains. Some of these extracts were found to be active against some bacterial strains. The methanolic extract exhibited a superior level of antibacterial activity. All of the extracts were active against Vibrio chlorea.

In the present study antioxidant activity of the plant was assessed. For this purpose Cyperus rotundus was extracted by using different extraction solvents and evaluated for their antioxidant activity using different in vitro antioxidant assays. Total flavonoids contents in methanol extracts of Cyperus rotundus (8.15-18.25 mg CE/g of dry matter) were higher as compared to ethanol extracts (6.44...

Background and objectives: The goal of this study was to compare the cytotoxic and antioxidant activities of the corms extracts of two Crocus species (C. sativus L. and C. pallasii subsp. haussknechtii). Methods: n-Hexan, chloroform and methanol extracts of the corms were prepared. Cytotoxic activities of the extract...

Background: Microbial biofilms are responsible for many human infections and increase of antibiotic resistant bacteria. Therefore, finding an efficient way to prevent infection and biofilm formation of bacteria is essential. Medicinal plants are among suitable candidates to inhibit biofilm formation of bacteria. The aim of this study was to evaluate the antimicrobial effects of...
