essential oils are volatile, natural, complex compounds formed by aromatic plants as secondary metabolites. in nature, essential oils play an important role in protecting plants in form of antibacterials, antivirals, antifungals, insecticides properties and also against herbivores. they also may attract some insects to use them in dispersion of pollens and seeds, or repel undesirable others. pr...

pennyroyal, an aromatic herb, is considered by food and medicine industries. it grows in different countries and provides various technological and functional properties. essential oils (especially ‘pulegune’) are the effective materials of pennyroyal that causes anti-microbial, anti-oxidant and aromatic properties. these essential oils have significant effects on preventing growth of several s...

conclusions results have shown that a. spicigera eo before and after flowering has antioxidant properties and therefore can be used in combination with other preservatives to protect food materials against a variety of oxidative systems. background essential oils (eo), also called volatile odoriferous oil, are aromatic oily liquids extracted from different parts of plants. in general, the const...

the effects of drought and salinity stress on the growth and chemical compositions pennyroyal(mentha pulegium l.) plant were investigated. this experiment was carried out in a factorial-randomized design with four replications in controlled conditions and plantlets were subject to four soil moisture regimes (40, 60, 80 and 100 of field capacity (fc)) and five salt treatments with 0, 25, 50, 75 ...

background and objective: considering the increasing tendency of public towards green consumption and the dangers of artificial additives, this study aimed to assess antibacterial activity of essential oils of cinnamomum zeylanicum, mentha piperita l., zataria multiflora boiss and thymus vulgaris against three important pathogenic and spoilage bacteria (pseudomonas fluorescens, erwinia carotovo...

background and objectives: the chemical composition and antimicrobial activity of bitter orange (citrus aurantium) leaf, ripe and unripe peel essential oils, cultivated in southwest of iran, were investigated. materials and methods: the analysis of chemical composition of hydro-distilled essential oils was carried out by gc-ms. the disc diffusion and broth micro-dilution were used to assay the ...

Acetone was investigated and found to be an appropriate alternative to Triton X-100 as a solvent of essential oils in bioassays aimed to investigate their effects on pinewood nematode (Bursaphelenchus xylophilus) mortality. Therefore it was used as dilution agent to screen the effectiveness of fifty two essential oils against this pest. Thirteen essential oils were highly effective, resulting i...
