development of a green belt with suitable plant species around the source of emission can mitigate the atmospheric contamination. selection of such plant species are required to combat air pollution based on their tolerance level. present study was undertaken to evaluate the tolerance level of higher plants in east of esfahan city, iran, during 2011 in terms of assessing air pollution tolerance...

BACKGROUND The production of nanoparticles using a biosystem is considered green chemistry. Application of plant extracts as a biological process has been proven to be suitable for synthesis of nanoparticles. OBJECTIVES This study designed in order to evaluate the production of silver nanoparticles using Juglans regia leaf extract and to compare the outcome of different preparation methods of...

introduction: our previous studies showed that hydroalcoholic extract of leaf of vitis vinifera relaxes the phenylephrine-induced contraction in rat thoracic aorta. this effect was dependent on endothelial integrity and no-cgmp system. the vasorelaxant effect of extract was much lesser on kcl-induced contraction. we, therefore, postulated that k+ channels are involved. the main aim of the prese...

BACKGROUND & OBJECTIVES Mosquitoes transmit serious human diseases, causing millions of deaths every year and the development of resistance to chemical insecticides resulting in rebounding vectorial capacity. Plants may be alternative sources of mosquito control agents. The present study assessed the role of larvicidal activities of hexane, chloroform, ethyl acetate, acetone, and methanol dried...

Peganum harmala L. (Zygophyllaceae) is one of the most famous medicinal plants used in traditional medicine of Iran. The aim of this study was to consider antibacterial effects of the methanolic extract of different parts of P. harmala including root, stem, leaf, flower and seed against some important human pathogenic bacteria. Antibacterial properties of methanolic extract of mentioned parts w...

We examined the inhibitory effects of loquat methanol extract on the adhesion, migration, invasion and matrix metalloproteinase (MMP) activities of MDA-MB-231 human breast cancer cell line. Cells were cultured with DMSO or with 10, 25, or 50 microg/ml of loquat methanol extract. Both leaf and seed extracts significantly inhibited growth of MDA-MB-231 cells in a dose-dependent manner, although l...

Gymnema sylvestre Wild R.Br (family: Asclepidaceae) is a valuable medicinal plant used in folk medicine to treat diabetes, obesity, asthma etc. in India for antiquity. Diabetes mellitus is a syndrome characterized immunologically by lymphocyte apoptosis and reduced cell-mediated and humoral immunity. Modulation of immune responses to alleviate diseases has been of interest, and traditional herb...

OBJECTIVE To identify the hepatoprotective and in vitro antioxidant activity of Lumnitzera racemosa (L. racemosa) leaf extract. METHODS Animals in Group 1 served as vehicle control, Group 2 served as hepatotoxin (CCL4 treated) group, Group 3 served as positive control (Silymarin) group, and Group 4, 5 and 6 served as (75, 150 and 300 mg/kg bw p.o.) L. racemosa leaf extract treated groups. Mor...

Andrographis macrobotrys Nees is an extensively utilized Indian traditional medicine to treat several human and livestock disorders. The present investigation was designed to evaluate the antibacterial, antifungal potentialities and phytochemical screening of the different leaves and stem extracts of Andrographis macrobotrys belongs to the family Acanthaceae. Methanol, ethanol, chloroform, acet...

Antiinflammatory activities of heat-treated Cassia alata leaf extract and kaempferol 3-O-gentiobioside (K3G) isolated from C. alata as an abundant flavonoid glycoside were studied by comparing their activities with the activities of sun-dried C. alata leaf extract. We observed strong inhibitory effects on Concanavalin A-induced histamine release from rat peritoneal exudate cells both in the ext...
