Abstract Mentha spicata L. (Lamiaceae), commonly called spearmint, is cultivated worldwide for its remarkable aroma and commercial value. Antimicrobial effectiveness of essential oils against many foodborne microorganisms when applied directly has been extensively demonstrated. The antimicrobial potential oil in the vapor phase different ( Salmonella enterica subsp. CCM 3807, Yersinia enterocol...

  Background : Pseudomonas aeruginosa is one of important opportunistic pathogen, that cases serious infections . It produces many virulence factors, and this bacterium usually is resistance against antimicrobial agents.   Objective :The aim of this study was evaluate the effects of sub-MICs of essential oils of Mentha spicata and Cumminum cyminum on alginate production, biofilm formation, swim...

Natural products, known for their medicinal properties since antiquity, are continuously being studied for their biological properties. In the present study, we analyzed the composition of the volatile preparations of essential oils of the Greek plants Ocimum basilicum (sweet basil), Mentha spicata (spearmint), Pimpinella anisum (anise) and Fortunella margarita (kumquat). GC/MS analyses reveale...

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 postharvest life of most fruit, vegetables and cereals is limited by fungal proliferation. chemical composition Mentha piperita, M. spicata suaveolens essential oils (EO), the antifungal activity against four pathogenic post-harvest fungi isolated from food, were herein investigated to evaluate their potential as natural food preservatives. EO obtained hydrodistillation aerial parts leaves,...

Ruminal inoculum enriched with particle-associated microorganisms was collected from rumen cannulated Santa Inês wethers grazing tropical grass pasture and a supplement based on ground corn and soybean before feeding and used to evaluate effects of some commercial essential oils (EO) on ruminal fermentation and methane emission in vitro. The investigated EOs were orange EO (Citrus sinensis, CrS...

The p-menthane monoterpenes of the Mentha species are biosynthesized from geranyl pyrophosphate via the monocyclic olefin 4S-limonene. A monoterpene cyclase was isolated from both Mentha x piperita (peppermint) and Mentha spicata (spearmint) that catalyzes the cyclization of geranyl pyrophosphate to 4S-limonene. This enzyme, 4S-limonene synthase, was purified to apparent homogeneity by dye liga...

Mints are herbaceous perennial plants with aromatic leaves that are cultivated for their essential oils. The essential oil of Mint used in pharmaceutical, perfumery and cosmetics applications. The aim of this study was to analyze the relationship between nine different genotypes of Mentha spicata and M. piperita collected from different regions of Ir...
