Present study was conducted to explore the herbicidal effect of volatile essential oil of Mentha longifolia (L.) L. and Chenopodium ambrosioides L. against Avena fatua L. weed. A significant effect of essential oil was observed on early seedling growth, chlorophyll content and cellular respiration over a concentration range of 0.01 – 0.25 mg/ml as compared to control ones. More inhibition was o...

Background & Aim: Peppermint (Mentha piperita L.) oil is one of the most popular and widely used as an essential oil. The aim of this study was to identify of the chemical components of peppermint cultivated in Isfahan climatic conditions. Experimental: The aerial parts of the plants were collected from a filed in Meymeh, Isfahan province in 2012. The essential oil was extracted by a ...

Introduction: The members of the genus Tanacetum are important medicinal plants. This study investigated the chemical composition and antibacterial activity of Tanacetum lingulatum and Tanacetum polycephalum essential oils on human infectious bacteria. Methods: The aerial part of two plants were collected from Urmia Province, Iran. The essential oils were extracted using a Clevenger device. The...

The objective of this study was to determine inhibitory activities of four volatile plant essential oils (cinnamon oil, fennel oil, origanum oil and thyme oil) on in vitro growth of Fusarium oxysporum f. sp. fragariae causing Fusarium wilt of strawberry plants. Results showed that these essential oils inhibited in vitro conidial germination and mycelial growth of F. oxysporum f. sp. fragariae i...

background & aim: salvia spinosa l. is a perennial shrub and aromatic plant belongs to the family lamiaceae. s. spinosa grows wild in some districts of iran. the aim of this study was to identify of the chemical components of s. spinosa in isfahan climatic conditions. experimental: the aerial parts of the plants were collected from isfahan province in 2014. the essential oil was extracted ...

In our screening program for new agrochemicals from local wild plants, Artemisia capillaris and A. mongolica were found to possess insecticidal activity against the maize weevil, Sitophilus zeamais. The essential oils of aerial parts of the two plants were obtained by hydrodistillation and were investigated by GC and GC-MS. The main components of A. capillaris essential oil were 1,8-cineole (13...

The essential oils isolated from basil (Ocimum sp.), chamomile (Chamomilla recutita L.), thyme (Thymus vulgaris L.) and oregano (Origanum sp.) were analysed rapidly and non-destructively applying different vibrational spectroscopic methods (ATR-IR, NIR and Raman spectroscopy). Whereas NIR spectroscopic data can be interpreted only by application of chemometric algorithms, IR and Raman spectra o...

Ruta species are known as a potential source of natural products with biological activities. They are used in several fields such as in therapeutic and traditional medicine. In order to contribute to the valorization of these plants, this work investigated the chemical composition and antibacterial activity of the essential oils of Ruta montana and Ruta gravelons growing in tunisia (north o...

background & aim: organophosphates are frequently used as insecticides in households, in agricultural areas and veterinary, thus posing a risk for accidental dermal exposure or through inhalation. acute organophosphate poisoning causes thousands of human mortalities each year in developing countries.   material & methods: this study carried out to study an antitoxic effect of endemic ir...

abstract         background and objective: lavandula stoechas is a species of native and permanent plants in golestan province that belongs to the family lamiaceae. l. stoechas has been used in traditional medicine for treatment of various diseases. the aim of this study was to extract essential oil using steam distillation method from the flowers of l. stoechas collected from jahan-nama region...
