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...

Moist and temperate Caspian forests are associated with a diversity of soil types and topography.  Although, natural history and ecological attributes of the Caspian vegetation is well-documented, little is known about mycorrhizae of the Caspian (Hyrcanian) flora. Samples of herbaceous plant species were collected from 4 pre-determined altitudes (-13 upto about 1500m above sea level, appro...

The radiolabeled leucine incorporation technique for quantifying rates of bacterial production has increased in popularity since its original description for bacterioplankton communities. Prior studies addressing incorporation conditions (e.g., substrate saturation) for bacterial communities in other habitats, such as decaying plant litter, have reported a wide range of final leucine concentrat...

Rubia cordifolia Linn. a flowering plant species from family Rubiaceae is an important medicinal plant. It is known to have anti-diabetic, antiseptic and antistress properties. In the present paper, antiglycation, antioxidant and antidiabetic activities of roots of Rubia cordifolia Linn. were investigated. Anti-AGE (Advance glycation end products) effect of Rubia cordifolia Linn. on glycation o...

Plants form the foundation for our global ecosystem and are essential for environmental and human health. With an increasing number of available plant genomes and tractable experimental systems, comparative and functional plant genomics research is greatly expanding our knowledge of the molecular basis of economically and nutritionally important traits in crop plants. Inferences drawn from comp...

Many species of Teucrium were used traditionally in treatment of inflammatory disorders. The present study aimed to assess the anti-inflammatory effect of methanolic extract of aerial parts of Teucrium oliverianum Ging. ex. Benth. (family, Lamiaceae). The extract was evaluated using the carrageenan-induced rat paw edema (Acute and sub-acute models), and turpentine oil–induced granuloma pouch bi...

In many terrestrial ecosystems nitrogen (N) limits productivity and plant community composition is influenced by N availability. However, vegetation is not only controlled by N; plant species may influence ecosystem N dynamics through positive or negative effects on N cycling. We examined four potential mechanisms of plant species effects on nitrogen (N) cycling. We found no species differences...

Background and Purpose: Treatment of life-threatening fungal infections caused by Candida species has become a major problem. Candida spp. are the most important causative agents of candidiasis. Allium tripedale is a medicinal plant that has been traditionally used to treat infections. In the present study, we aimed to determine the chemical compounds and antimicrobial activity of hydroalcoholi...
