We examined the biotransformation of enantiomeric pairs of enones such as pulegone and carvone in recombinant Escherichia coli expressing Nicotiana tabacum pulegone reductase. It was found that recombinant E. coli cells acquired the ability for stereospecific hydrogenation of the exocyclic C=C double bond of pulegone. However, stereospecificity in hydrogenation with the recombinant E. coli cell...

results analysis of the essential oil revealed the presence of pulegone (68.59%) piperitone (7.8%), piperitenone (7.8%), 1, 8-cineole (1.3%), and carvacrol (1.6%) as the major components. the results showed a significant activity against mdr a. baumannii with inhibition zones and minimal inhibitory concentration values in the ranges of 7-15 mm and 20-35 µl/ml respectively. conclusions this inve...

background: mentha longifolia is one of the aromatic medicinal plant belongs to lamiaceae family. there are some active ingredients in the essential oil of m. longifolia, which potentially could impair the hepatic function. the aim of this study was to find the maximum dose of essential oil of m. longifolia (eoml) that does not show any hepatic deterioration. methods: adult wistar rats fed diff...

Peppermint has considerable commercial value and widely cultivated for essential oil production, especially menthol. The aim of this study was to determine the quantitative expression of pulegone reductase (pr), menthofuran synthase (mfs) and limonene synthase (ls) genes in menthol biosynthesis pathway in Mentha x piperita , using semiquantitative RT-PCR analysis and evaluating menthol producti...

Ziziphora tenuior is one of the traditional medicinal herbs; the main active chemical composition of this herb is an ingredient named as Pulegone which is known well for its anti-inflammatory and analgesic effects. Considering, the side effects of synthetic drugs, researcher’s attention has been attracted to the use of herbal medicines.In this study, after inducing ear edema via Xylenol, the an...

Doogh is the most popular and commonly consumed yoghurt-based Iranian drink. The aim of this study was to investigate the antibacterial effects of Ziziphora clinopodioides essential oil (ZEO) at 0.10 and 0.20% concentrations, nisin at 250 and 500 IU mL-1, and their combination against Salmonella typhimurium and Staphylococcusaureus in doogh during storage a...

The aim of the present study was to determine the chemical structures of the isolated compounds, the essential oil and fatty acid compositions of Mentha longifolia subsp. noeana with their biological activities. Ursolic acid (1), uvaol (2), stigmast-5-ene-3-yl formate (3), stigmast-5-en-3-one (4), -sitosterol (5), bis(2ethylhexyl) benzene-1,2-dicarboxylate (6), hexacosyl (E)-ferulate (7) and ...
