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 cleven...

The study was aimed to investigate essential oil chemical composition (gas chromatography/flame ionization detection [GC-FID] and gas chromatography/mass spectrometry [GC-MS]) and antioxidant (1,1-diphenyl-2-picrylhydrazyl free radical (DPPH) and 2,2'-azinobis-3-ethylbenzothiazoline-6-sulphonate [ABTS] assays) and antimicrobial (Gram-positive and Gram-negative bacteria, fungi, and yeast) activi...

BACKGROUND This is the first report testing the antibiotic resistance-modifying activity of Mentha arvensis against MRSA (methicillin-resistant Staphylococcus aureus). MATERIALS AND METHODS In this study an ethanol extract of Mentha arvensis L. and chlorpromazine were tested for their antimicrobial activity alone or in combination with conventional antibiotics against MRSA strains. RESULTS ...

Interactions between herbivorous insects and plants storing terpenoids are poorly understood. This study describes the ability of Chrysolina herbacea to use volatiles emitted by undamaged Mentha aquatica plants as attractants and the plant's response to herbivory, which involves the production of deterrent molecules. Emitted plant volatiles were analyzed by GC-MS. The insect's response to plant...

HE major components of Mentha oils are a principal ketone, and its related alcohol and ester. Since these compounds account for 75-85 percent of the oil by weight, an elementary genetic understanding of their origin and relationship would seem important to any plant breeding work. In this paper, we wish to consider the genetic relationship between the ketone (menthone) and its related alcohol (...

The objective of this study was to investigate the chemical composition and in vitro antifungal activity Mentha × Piperita L. (peppermint) essential oil (EO) against some plant pathogenic fungi (Alternaria alternata, Penicillium expansum, Rhizoctonia solani, Rhizopus stolonifer). Antifungal EO selected conducted using agar diffusion method by adding peppermint concentrations (0, 250, 500, 750, ...
