Background and objectives: Plant essential oils are sometimes considered for use as antimicrobial agents in foods and medicines and they could be combined with other antimicrobial agents to strengthen the effect and/or reduce the required dose. This study was conducted to determine the chemical composition of the Ocimum basilicum, Salvia officinalis and Trachyspermum ammi essential oils and eva...

Rhizo-bacteria of high biocontrol potential against different Fusarium isolates were bio-assayed under both laboratory and greenhouse conditions. Eighty five rhizo-bacteria isolated from the rhizosphere of plants growing in various desert areas were screened for their antagonistic activity against eight Fusarium isolates (four isolates of Fusarium solani and four isolates of Fusarium oxysporum)...

Two field experiments were conducted in Aly Mubark experimental Farm in sandy soil at El-Bustan Sandy soil irrigated by drip irrigation, during 2003 and 2004 seasons. The experiments aimed to study the effect of three irrigation treatments with three different kinds of fertilizers and its concentration on sage growth, yield, essential oil yield and components, macro-nutrients content in dry her...

Biofilms formed by fungal organisms are associated with drastically enhanced resistance against most antimicrobial agents, contributing to the persistence of the fungi despite antifungal therapy. The purpose of this study is to combine the unique properties of nanoparticles with the antimicrobial activity of the Rosmarinus officinalis essential oil in order to obtain a nanobiosystem that could ...

Extensive research suggests that a number of plant-derived chemicals and traditional Oriental herbal remedies possess cognition-enhancing properties. Widely used current treatments for dementia include extracts of Ginkgo biloba and several alkaloidal, and therefore toxic, plant-derived cholinergic agents. Several non-toxic, European herbal species have pan-cultural traditions as treatments for ...

Prostaglandin E(2) (PGE(2)), the most relevant eicosanoid promoting inflammation and tumorigenesis, is formed by cyclooxygenases (COXs) and PGE(2) synthases from free arachidonic acid. Preparations of the leaves of Salvia officinalis are commonly used in folk medicine as an effective antiseptic and anti-inflammatory remedy and possess anticancer activity. Here, we demonstrate that a standard et...

Garlic (Allium sativum L., Alliaceae), Persian shallot (Allium ascalonicum L., Alliaceae ) and Sage (Salvia officinalis L., Lamiaceae) are believed to have hypoglycemic properties and have been used traditionally as antidiabetic herbal medicines in Iran. In this study, diabetes was induced by subcutaneous injection of alloxan monohydrate (100 mg kg(-1)) to male Wistar rats. Antidiabetic effects...

PURPOSE Salvia officinalis L., also known as Maryam Goli, is one of the native plants used to Persian medicinal herbs. Hence, the objective of this study was to examine the in vitro cytotoxic activities of a standardized crude methanol extracts prepared from Salvia officinalis L., on a non-Hodgkin's B-cell lymphoma (Raji) and human leukemic monocyte lymphoma (U937), Human acute myelocytic leuke...

Gene flow, natural selection and genetic drift are processes that play a major role in shaping the genetic structure of natural populations. In addition, genetic structures of individual populations are strongly correlated with their geographical position within the species distribution area. The highest levels of genetic variation are usually found in the centre of a species' distribution and ...
