background: natural antioxidants with plant origin are incorporated to foods in the forms of essential oils or extracts. they can retard lipid oxidation and control spoilage bacteria in foodstuffs (e.g. meat products). objective: this work was aimed to evaluate the effect of nitrite partial replacement with mentha piperita essential oil (mpeo) on oxidative, microbial and sensory properties of c...

Purpose: To determine, in Sprague Dawley rats, the toxicity profile of the methanol extract of Mentha spicata, a plant used in folklore medicine for the treatment of various forms of pain. Methods: The plant extract, at concentrations ranging from 100 0.07 mg/ml, was used to determine the median lethal concentration (LC50) based on brine shrimp lethality assay. Artificial sea water served as co...

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...

Bu çalışmada, Fumigant olarak uygulanan farklı dozlardaki (1, 3, 5 µl/l-1 hava dozu) nane esansiyel yağının Ephestia kuehniella (Zeller)’in iki gelişim evresinin (son dönem larva ve ergin dişi) biyolojik parametreleri üzerindeki zamana bağlı etkisi incelenmiştir. Nane uçucu yağına maruz kalan son evre larvaların koza örme süresi, puplaşma pupal periyot, öncesi süresi ağırlığı ile birlikte bu di...

BACKGROUND: The use of antibiotics as feed additive in animal feeds due to the appearance of residues in milk and meat and their effects on human health has restricted. Two of essential oils with high potential for use in ruminant diet are Mentha piperita (peppermint) and Mentha pulegium (pennyroyal) essential oil. OBJECTIVE: This study was conducted to investigate the effects of essential oils...

The essential oils of peppermint (Mentha x piperita) and spearmint (Mentha spicata) are distinguished by the oxygenation position on the p-menthane ring of the constitutive monoterpenes that is conferred by two regiospecific cytochrome P450 limonene-3and limonene-6-hydroxylases. Following hydroxylation of limonene, an apparently similar dehydrogenase oxidizes (2)-trans-isopiperitenol to (2)-iso...

Essential oil, ethanolic extract and decoction of 10 plant species from interior Portugal were analyzed for their activity towards acetylcholinesterase (AChE) enzyme and their antioxidant activity. Of these, Melissa officinalis, Paronychia argentea, Sanguisorba minor, Hypericum undulatum and Malva silvestris are used in herbal medicine, Laurus nobilis and Mentha suaveolens as condiments, and Sa...

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, ...
