OBJECTIVE Boerhaavia elegans L. (Nyctaginaceae) is a medicinal plant used for the treatment of kidney disorders, urinary tract disorders and blood purification in Baluch tribe. The aim of present study is to evaluate the antioxidant property of B. elegans species for the first time. MATERIALS AND METHODS Different parts (leaf, stem and fruit) of the plant were extracted by using various solve...

the species heracleum rawianum belongs to apiaceae, is one of the native species in iran. the leaves and fruits of heracleum rawianium are used traditionally in iran as flavouring agent and spice for food. in the present work, the extraction of aerial parts of this plant with acetone by maceration is described. our phytochemical analysis of the chloroform extract of the aerial parts of this pla...

Arnebia euchroma is from Boraginaceae family. Various therapeutic effects have been reported for different species of this plant. The aim of this study was to investigate antioxidant activity of hydroalcoholic extract of the root of A. euchroma and its protective effect on hepatotoxicity induced by CCl4 in mice. In this experimental study, A. euchroma was extracted with ethanol solvent by macer...

Most studies of density dependent regulation in plants consider a single target species, but regulation may also occur at the level of the entire community. Knowing whether a community is at carrying capacity is essential for understanding its behaviour because low density plant communities may behave quite differently than their high density counterparts. Also, because the intensity of density...

Forty-one methanol extracts of 28 indigenous medicinal plant species were tested for their insecticidal bioactivity against cotton whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), adults and second nymphal instars under controlled conditions. This study is within a bioprospection context, in the form of utilizing local plant species as an alternative in sustainable agriculture dev...

Iran is the largest producer of saffron (Crocus sativus) in the world. More than 80% of higher plant species have a mutual relationship with mycorrhizal fungi, which enhances the plant growth and its productivity. With identification of native arbuscular mycorrhizal fungi and their application, it could be possible to expand saffron cultivated area and increase the performance of arable lands. ...

AIM OF THE STUDY To provide ethnopharmacological basis for the medicinal use of Lepidium sativum seeds in indigestion and constipation. MATERIALS AND METHODS The in vivo studies were conducted in mice, while isolated tissues of mouse, guinea-pig and rabbit were suspended in tissue bath to measure isotonic contractions. RESULTS The aqueous-methanolic extract of Lepidium sativum seeds (Ls.Cr)...

Background: Artemisia species with common Persian name of Dermaneh are found all over Iran and are used for treatment in infectious diseases such as malaria, hepatitis and other diseases. Some Artemisia species are used in traditionally as tonic and anti-helmintic in north of Iran. Objective: The aim of this study was to investigate chemical composition of the essential oil of Artemisia haussk...

BACKGROUND The systematic analysis of a large number of comparable plant trait data can support investigations into phylogenetics and ecological adaptation, with broad applications in evolutionary biology, agriculture, conservation, and the functioning of ecosystems. Floras, i.e., books collecting the information on all known plant species found within a region, are a potentially rich source of...

Horizontal gene transfer (HGT) describes the transmission of genetic material across species boundaries and is an important evolutionary phenomenon in the ancestry of many microbes. The role of HGT in plant evolutionary history is, however, largely unexplored. Here, we compare the genomes of six plant species with those of 159 prokaryotic and eukaryotic species and identify 1689 genes that show...
