BACKGROUND Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder, which may result from alteration of the gastrointestinal microbiota following gastrointestinal infection, or with intestinal dysbiosis or small intestinal bacterial overgrowth. This may be treated with antibiotics, but there is concern that widespread antibiotic use might lead to antibiotic resistance. S...

An experimental steam distillation unit has been designed, built, and tested for the extraction of essential oils from peppermint and spearmint. The unit, using a 130-gal (510-liter) distillation tank, is intermediate in size between laboratoryscale extractors and commercial-sized distilleries, yet provides oil in sufficient quantity for industrial evaluation. The entire apparatus-a dieselfuel-...

the aim of this study was to assess the effect of several doses of spearmint essential oil (seo; 0, 250, 500, 750 or 1,000 µg ml-1 buffered rumen fluid) on the fermentation kinetic and digestibility using in vitro gas production technique. a total mixed ration (30% roughage: 70% concentrate) was incubated with buffered rumen fluid. in vitro gas production, asymptotic gas production (a), rate of...

Medicinal plants have high importance in medicine and pharmacogonosy because of their secondary metabolites. Essential oils, antioxidants and flavonoids are the major compounds of many medicinal plants. These compounds especially antioxidants can increase oxidation of DNA in response to wounds. Nowadays, progresses in biotechnology such as molecular markers were used for phylogenetic relationsh...

Glycerol menthonide has been reported in the literature and has been prepared by reaction of menthone with glycerol under acid catalysis. The menthonide was originally prepared as an additive to spearmint gum by a chemist at Wrigley’s Inc. No further chemical analysis of the menthonide has been reported in the literature. However, glycerol menthonide should be a mixture of up to 6 isomers. Spar...

abstract background and objectives: soil salinity is one of the most important limited factors of plant productions. physiological drought resulting from salinity stress is one of the main reasons of limiting water absorption from soil. moreover, increasing the salt absorption by plants cause to disorder in physiological and cellular processes. spearmint (mentha spicata l.) is from lamiaceae fa...

Seventeen mint accessions representing the three species grown for commercial oil production in the United States were characterized using randomly amplified polymorphic DNA (RAPD) analysis. The RAPD profiles readily identified the different Mentha species; calculation of genetic distance, based on the number of shared bands, indicated that M. spicata L. is more closely related to M. x gracilis...
