The aim of the present study was to investigate the chemical composition of the essential oil of Artemisia vestita and to determine the antibacterial activity of the essential oil and its two major components, grandisol and 1,8‑cineole, against certain respiratory infection‑causing bacterial strains, in vitro and in vivo. The chemical composition of the essential oil was analyzed using gas chro...

Abstract Ethanol solutions of five fractions obtained from essential oil of sweet basil Ocimum basilicum L. (Lamiales: Lamiaceae) (F1-F5) were tested for their antifeedant properties against 2(nd) instar gypsy moth larvae, Lymantria dispar L. (Lepidoptera: Lymantriidae), in laboratory non-choice and feeding-choice experiments. Prior to bioassays, the chemical composition of each fraction was de...

In the present study effort have been made to find the anti-bacteria effect of six medicinal plant essential oil namely, Ocimum bascilicum (Basil oil), mentha arvensis (Cormint oil),Zingiber officinale(ginger oil),citrus limon(lemon oil), thymus mastichina (Marjoram oil) and mentha spicata (Spearmint oil) were assessed for anti bacterial activity against therefore pathogenic bacteria such as B....

the essential oils from compositae specie of iran: centaurea behen l. obtained by hydrodistillation was analyzed by gc and gc/ms.  β-caryooyllane (24.5%), β-selinene (13.9%) and valencene (11.7%) were the main components among the sixteen constituents characterized in the oil of centaurea behen representing  93.7% of the total components detected.

introduction: to assess the antibacterial effects of an iranian endemic essential oil, satureja khuzistanica jamzad (skj) when used as an intracanal antiseptic and interappointment medicament. materials and methods: antimicrobial activity and minimum inhibition concentrations (mics) of skj essential oil with and without calcium hydroxide (ch) against eleven aerobic, microaerophilic and anaerobi...

hydro-distilled volatile oils from the flowers and leaves of eupatorium cannabinum l. which gathered in touchal on mountain alborz (tehran province) in iran were investigated mainly by a combination of gc and gc/ms. thirty-nine components were identified in the oils. the main constituents of the essential oils in flowers and leaves were germacrene d (27.3%, 37.1%), gemacrene b (12.4%, 11.7%) an...

background: biosynthesis and metabolism of phytochemicals in medicinal and aromatic plants are vigorously affected by different abiotic elicitors including chemicals. objective: this experiment was designed to investigate the effects of three levels of copper sulfate (cu: 0, 5, 25 mg kg-1) and zinc sulfate (zn: 0, 10, 50 mg kg-1) and their combinations on yield, chemical compositions of essenti...

background: the genus psammogeton edyew. which belong to the umbelliferae family, is found in central areas of asia. this genus consists of six species widespread in the sandy dunes of deserts. among the four species present in iran, pssamogeton canescens (dc.) vatke is distributed in regions of iran central. objective: the aim of this study is to determine the chemical composition of essential...

background: achillea tenuifolia lam. (compositae) with small yellow flowers and several times pinnately divided leaves in worm shape is known for many years in the folk medicine. it has been used to reduce sweating and to stop bleeding. it helps regulation of the menstrual cycle and reduces heavy bleeding and pain. materials and methods: plant material (flower, leaf and stem) was collected in k...
