Latest Research on Mentha Piperita: Oct – 2019

October 1, 2019October 1, 2019 by Editor NetKumar

Antimicrobial Screening of Mentha piperita Essential Oils

Essential oils of peppermint mint L. (Lamiaceae), that ar employed in flavors, fragrances, and prescription drugs, were investigated for his or her antimicrobial properties against twenty one human and plant unhealthful microorganisms. The bioactivity of the oils lotion and menthone was compared victimization the mixture of in vitro techniques like microdilution, agar diffusion, and bioautography. it absolutely was shown that each one of the peppermint oils screened powerfully repressed plant unhealthful microorganisms, whereas human pathogens were solely moderately repressed. Chemical compositions of the oils were analyzed by gigacycle per second and GC/MS. victimization the bioautography assay, lotion was found to be accountable for the antimicrobial activity of those oils.

A review of the bioactivity and potential health benefits of peppermint tea (Mentha piperita L.)

Peppermint (Mentha piperita L.) is one amongst the foremost wide consumed single ingredient flavoring teas, or tisanes. Peppermint tea, brewed from the plant leaves, and also the volatile oil of peppermint are utilized in ancient medicines. Evidence‐based analysis relating to the bioactivity of this herb is reviewed. The phenolic resin constituents of the leaves embrace rosmarinic acid and a number of other flavonoids, primarily eriocitrin, luteolin and hesperidin. the most volatile parts of the volatile oil are lotion and menthone. In vitro, peppermint has vital antimicrobial and antiviral activities, robust inhibitor and growth actions, and a few antiallergenic potential. Animal model studies demonstrate a relaxation result on duct (GI) tissue, analgesic and anesthetic effects within the central and peripheral systema nervosum, immunomodulating actions and chemopreventive potential.

Effects of essential oil from mint (Mentha piperita) on Salmonella enteritidis and Listeria monocytogenes in model food systems at 4° and 10°C

The result of mint (Mentha piperita) oil (0•5, 1•0, 1•5 and 2•0%, v/w) on Salmonella enteritidis and L. monocytogenes in a very substance and 3 model foods; tzatziki (pH 4•5), taramosalata (pH 5•0) and pâté (pH 6•8), inoculated at 107 cfu g‐1, at 4° and one0°C for ca 1 week was studied. within the substance supplemented with the oil, no growth was determined over two d at 30°C determined by a electrical phenomenon technique with a Malthus 2000 growth analyzer. Salmonella enteritidis died in tzatziki all told treatments and declined within the different foods apart from pâté at 10°C as judged with viable counts. L. monocytogenes populations showed a declining trend towards the tip of the storage amount however was exaggerated in pâté. [3]

Identification of an Artefact on Chromatograms of the Keto-acid 2,4-Dinitro-phenylhydrazones

DURING a study of plant keto-acids dispensed by one in every of US (G. H. N. T.) below the direction of faculty member. F. C. Steward at university, associate degree unknown substance, hereafter selected compound I, was found within the keto-acid fraction of all plant tissues examined1. This substance was isolated in crystalline kind (sint. 206°, decomp. 214°) from the keto-acid dinitrophenylhydrazone fraction of mint leaves by extraction from associate degree corundum column with one per cent salt. Its position on chromatograms was almost like that of the slower-moving spot of acid dinitrophenylhydrazone (Fig. 1, ref. 1). [4]

Evaluation of Antimicrobial Activity of Mentha piperita, Tragia involucrata (L) and Urtica massaica Used as Medicinal Plants in Tanzania

Aims: to judge antimicrobial activity of Mentha piperita, Tragia involucrata (L) and Urtica massaica used as medicative plants in United Republic of Tanzania.

Study Design: Experimental study was disbursed by victimization ninety six wells small dilution methodology.

Place and period of Study: This study was conducted at Dodoma University, Dodoma-Tanzania, between Apr and July 2017.

Methodology: Minimum repressive concentration of plants extracts against the tested microorganism and flora species determined by victimization ninety six wells small dilution methodology. [5]
