essential oils from aerial parts of mentha spicata, was obtained by steam destillation using a clevenger-type system. these oils were screened for antibacterial and anti-candida albicans activity using bioautographic method. a fiel experiments was laid out in agricultural research farm, city namin, ardabil province, iran in 2013. experiment was conducted in a randomized complete block with seve...

there is little information available on morphological and agronomic traits, as well aschemical compositions of iranian mint landraces. this study was conducted to investigate themorphological, agronomic and oil content characteristics of iranian mint landraces using twelvelandraces, three of which belong to mentha longifolia, and the remaining, mentha spicata l, originatedfrom central regions ...

to study the effect of essential oils of medicinal plants on post-harvest stability of fruits quality and decay management of kinnow mandarin, this experiment was carried out as factorial in completely randomized design with four replications. essential oils of thyme, mint, fennel, rosemary, ajowan and cummin at two levels 500 and 750 ml/l were applied to wounded and non-wounded fruits, that ha...

The effect of vanillin and essential oil of mint on the growth of different strains of food spoilage yeasts in laboratory media and fruit purées was studied. Growth of Saccharomyces cerevisiae, Zygosaccharomyces rouxii, Debaryomyces hansenii and Z. bailii was inhibited in culture media and apple purée containing 2000 ppm of vanillin for 40 days storage at 27 degrees C and a(w) 0.99 or 0.95. But...

The use of essential oils in foods has attracted great interest, due to their antagonistic action against pathogenic microorganisms. However, this action is undesirable for probiotic foods, as products containing Lactobacillus rhamnosus. The aim of the present study was to measure the sensitivity profile of L. rhamnosus and a yogurt starter culture in fermented milk, upon addition of increasing...

BACKGROUND Essential oils, as secondary plant compounds, present a safer alternative to conventional insecticides in insect control programs. So five essential oils including eucalyptus, mint, yarrow, oregano and rosemary oils were evaluated against the brown-banded cockroach Supella longipalpa. METHODS Evaluation was done against the 3rd and 4th instar nymphs using three bioassay methods; co...

The repellency and toxicity of mint oil to American, Periplaneta americana (L.), and German, Blattella germanica (L.), cockroaches were evaluated in a series of laboratory experiments. In topical application experiments, mint oil was toxic to both species with toxicities (LD50s) of 2.57 (1.98– 4.20) in 10 l and 3.83 (2.35–7.34)% in 2 l for American and German cockroaches, respectively. In conti...

The essential oils (EOs) and static headspaces (HSs) of in vitro plantlets and callus of Mentha x piperita were characterized by GC-MS analysis. Leaves were used as explants to induce in vitro plant material. The EO yields of the in vitro biomass were much lower (0.1% v/w) than those of the parent plants (2% v/w). Many typical mint volatiles were emitted by the in vitro production, but the call...
