Vicia genus has 45 species in Iran. Many protective and biological activities have been reported from these species.  In spite of many works, nothing is known about protective effect of V. cracca against hypoxia conditions. In this study, protective effects of V. cracca extract against hypoxia-induced lethality in mice were evaluated by three experimental models of hypoxia, asphyctic, haem...

The crude extract of mangrove plant Rhizophora mucronata was prepared in this present work. The extract was testified for its anti-mosquito larvicidal property against two species of mosquito viz: Anopheles stephensi and Aedes aegypti. The 48 hours exposure of various dilutions of 100, 200, 300, 400, 500 ppm were given to the III to IV instar larval population. Percentage mortality data was ana...

Swertia species are widespread in Eastern and Southern Asian countries and used in traditional medicine as anti-pyretic, analgesic, gastro and liver tonic. Among different species, only Swertia longifolia grows in Iran. In this investigation, antioxidant, cytotoxic and acetylcholinesterase inhibitory activities of S. longifolia have been studied. Aerial parts and roots of the plant were collect...

Medicinal plant species has a valuable economic importance because of its usage as pharmaceuticals, nutritional, as well as its use in popular medication. For DNA-based techniques, nanogram quantities of the purified DNA are requisite to amplify and yield sufficient amounts of PCR products. SDS-based DNA isolation method was used to extract DNA from 11 species of different aromatic and me...

HPTLC analysis was carried out to determine the steroid compounds profile in the whole-plant samples of selected Polygonum species (P. chinense, P. glabrum and P. barbatum). The methanol extract of whole-plant samples obtained from Polygonum species (P. chinense, P. glabrum and P. barbatum) showed 6, 6 and 5 compounds, respectively, and were compared with stigmasterol and solasodine standards. ...

BACKGROUND Mosquitoes transmit serious human diseases, causing millions of death every year. Vector control is facing a threat due to the emergence of resistance to synthetic insecticides. Insecticides of botanical origin may serve as suitable alternative biocontrol techniques in the future. Nine different locally available medicinally important plants suspected to posse larvicidal property wer...

Studies that compare physiology, anatomy, and ecology across species have offered some of the best insight into adaptation and evolutionary constraints in plants. As a result, the comparative approach has become increasingly used in studies of plant physiological ecology. The high species diversity of Brazilian biomes provides many excellent opportunities for comparative plant ecophysiology, an...

The in vitro antimicrobial activity of the crude methanolic and ethanolic leaf extract of Bridelia retusa (L.) Spreng. was studied against four gram negative and two gram positive bacteria. The results showed that both the extracts showed antimicrobial activity. Maximum zone of inhibition was observed in the methanolic extract against Escherichia coli which was 29.5 ± 0.50. However, ethanolic e...

A multiplex polymerase chain reaction (PCR) assay for simultaneous, fast and reliable detection of the main soft rot and blackleg potato pathogens in Europe has been developed. It utilises three pairs of primers and enables detection of three groups of pectinolytic bacteria frequently found in potato, namely: Pectobacterium atrosepticum, Pectobacterium carotovorum subsp. carotovorum together wi...
