Seventeen mint accessions representing the three species grown for commercial oil production in the United States were characterized using randomly amplified polymorphic DNA (RAPD) analysis. The RAPD profiles readily identified the different Mentha species; calculation of genetic distance, based on the number of shared bands, indicated that M. spicata L. is more closely related to M. x gracilis...

cuminum cyminum linn. (umbelliferae) is a plant, which has been used as a toothache remedy in folk medicine of iran. in this study, the potential anti-nociceptive and anti-inflammatory activities of the fruit essential oil of c. cyminum has been evaluated in chemical (formalin test) and thermal (tail-flick test) models of nociception and formalin model of acute inflammation in rats and mice. th...

in order to study the response of concentration and composition of essential oil of coriander (coriandrum sativum) to cattle manure and nitrogen fixing bacteria, an experiment was conducted as factorial experiment in the base of randomized complete blocks design with twelve treatments and three replications at homand research station in damavand of iran in 2010. the factors were cattle manure i...

b a ckground: application of plant derivatives have been suggested as alternative sources for mosquito control. m ethods: the root essential oil and methanol extract of c ionura erecta (l.) griseb was tested under laboratory conditions for larvicidal and skin repelleny activities against anopheles stephensi . the chemical compositions of essential oils were analyzed using gas chromatography- ma...

Medicinal plants have high importance in medicine and pharmacogonosy because of their secondary metabolites. Essential oils, antioxidants and flavonoids are the major compounds of many medicinal plants. These compounds especially antioxidants can increase oxidation of DNA in response to wounds. Nowadays, progresses in biotechnology such as molecular markers were used for phylogenetic relationsh...

Effective bed bug (Cimex lectularius L.) monitors have been actively sought in the past few years to help detect bed bugs and measure the effectiveness of treatments. Most of the available active monitors are either expensive or ineffective. We designed a simple and affordable active bed bug monitor that uses sugar-yeast fermentation and an experimental chemical lure to detect bed bugs. The sug...

the chamomile species of anthemis triumfettii (l.) all is one of important medicinal plant belong to compositae family and it grows as wild species in zagros and alborz mountains, iran. the aim of this study was to evaluation of morphological and phenological traits and their relationships with essential oil. seeds of seven accessions were sown in jiffy pots and transferred to field using rando...
