The antioxidant capacity of essential oils of Mentha spicata L., Mentha x gentilis L., Mentha crispa L., Mentha piperita L. and Mentha x piperita L. was determined by using differential pulse voltammetry. This assay was based on the reduction in the limiting current value of the oxygen electroreduction, which was used to calculate the antioxidant capacity (K) of these species. The species M. x ...

Mentha piperita and Citrus sinensis was an aromatic plants well known for its fragrance and distinct aroma. In this prospective study to evaluate the chromatogram detection of ethanol extract of Mentha piperita and Citrus sinensis with standard flavonoid marker eriocitrin by HPTLC technique. HPTLC chromatogram was developed in ethanolic extract of Mentha piperita, Citrus sinensis and standard f...

BACKGROUND Mentha piperita L. (Labiatae) is an herbaceous plant, used in folk medicine for the treatment of several medical disorders. METHODS AND RESULTS In the present study, the aqueous extract of Mentha piperita leaf, at the i.p doses 200 and 400 mg/kg, showed significant analgesic effects against both acetic acid-induced writhing and hot plate-induced thermal stimulation in mice, with pr...

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...

Changes in essential oil composition of peppermint (Mentha x piperita L.) affected by yeast extract and salicylic acid foliar application

Background. Infantile colic is a distressing and common condition for which there is no proven standard treatment. Objective. To compare the efficacy of Mentha piperita with simethicone in treatment for infantile colic. Methods. A double-blind crossover study was performed with 30 infants attending IMIP, Recife, Brazil. They were randomized to use Mentha piperita or simethicone in the treatment...

Herbal and plant origin crude drugs with anti-lipid peroxidative activity had become a central focus for study of hepatoprotection due to its safety, efficacy and cost effectiveness. The aim of present study is to analyse the hepatoprotective and lipotropic effect of Mentha piperita leaf in CCl4 induced free radical mediated oxidative stress rats. In the present study, an attempt has been made ...

In the present study, we evaluated the antibacterial activity in the leaf extracts of Mentha piperita L. against pathogenic bacteria like Bacillus subtilis, Pseudomonas aureus, Pseudomonas aerogenosa, Serratia marcesens and Streptococcus aureus. The aqueous as well as organic extracts of the leaves were found to posses strong antibacterial activity against a range of pathogenic bacteria as reve...

Background and aims: Tooth decay is one of the most common chronic diseases around the world and this problem is the result of variety of different bacteria. Streptococcus mutants is one of the most important bacteria which is related to this disease. Finding new effective antibacterial agents is an important area in bioscience for fighting and controlling bacterial infections. Essential oils a...

BACKGROUND This study is aimed at determining the efficacy of Mentha spicata (M. spicata) and Mentha × piperita (M. × piperita) in preventing chemotherapy-induced nausea and vomiting (CINV). METHODS This was a randomised, double-blind clinical trial study. Prior to the study, patients were randomly assigned into four groups to receive M. spicata or M. × piperita. Statistical analysis included...
