Background: The rice weevil, Sitophilus oryzae and rice moth, Corcyra cephalonica are major and cosmopolitan insect. Adults of S. oryzae (male and female) and both larvae are insatiable feeders on a great variety of grains. Objective: This study was conducted to estimate the insecticidal effect of essential oils from peppermint, Mentha piperita L. and black pepper, Piper nigrum L. ag...
Essential oils are aromatic and volatile liquids extracted from plants. The chemicals in essential oils are secondary metabolites, which play an important role in plant defense as they often possess antimicrobial properties. The interest in essential oils and their application in food preservation has been amplified in recent years by an increasingly negative consumer perception of synthetic pr...
objective: nowadays notable increase in acquired resistance of candida species to antifungal drugs and necessity of using agents with antifungal properties is unavoidable. in some plants due to presence of components such as polyphenols have antimicrobial properties. in this study antifungal effects of essential oils of thymus vulgaris, petroselinum crispum, cuminum cyminum and bunium persicum ...
plant essential oils are natural products extracted from plants and because of their antimicrobial properties can be used as natural additives in foods. they are also useful for decontamination of food-borne pathogens and can be a safe additive in foods. the antimicrobial activities of essential oils belonging to saturiea hortensis, thymus vulgaris, mentha polegium, cuminum cyminum, lavandula o...
abstract: essential oils are commonly used to treat minor health problems. in this study the chemical compositions of lavandula officinalis and thymus vulgaris were determined by gas chromatography and mass spectrometry. gc/ms analysis of t. vulgaris resulted in thymol as the major oil component where as methyl sulfony exhibited as the most abundant constituent of l. officinalis. the antibacter...
Background & Aim: Secondary metabolites with bioactive and functional properties in essence of aromatic plants can be useful for improvement of quality and persistence of food as natural preservative. The aim of this study was to evaluate the in vitro antibacterial of essential oils of some of the medicinal plants collected from Chaharmahal va Bakhtiari Province, Iran. Experimental: ...
Zataria multiflora is one of the valuable medicinal plants belonging to the Lamiaceae family. The aromatic aerial parts of this species are traditionally used by endemic folks to flavor some native foods, also for numerous therapeutic functions.

BACKGROUND & OBJECTIVES Many essential oils have been reported as natural sources of insect repellents; however, due to high volatility, they present low repellent effect. Formulation technique by using microencapsulation enables to control the volatility of essential oil and thereby extends the duration of repellency. In this study, the effectiveness of microencapsulated essential oils of Alpi...
BACKGROUND Insects are mostly pathogens transmitters, thus the necessity of finding effective bioinsecticides to combat them. In the present investigation, the insecticide activity of Ageratina jahnii and Ageratina pichinchensis (Asteraceae) essential oils, methanol, and aqueous extracts was evaluated against Lutzomyia migonei (Diptera: Psychodidae) females, Leishmania transmitters, a wide dist...
The crude extracts of plants from Asteraceae and Lamiaceae family and essential oils from Salvia officinalis and Salvia sclarea were studied for their antibacterial as well as antibiotic resistance modifying activity. Using disc diffusion and broth microdilution assays we determined higher antibacterial effect of three Salvia spp. and by evaluating the leakage of 260 nm absorbing material we de...
