The objective of the present study was to evaluate the phytochemical constitution and antioxidant activity of methanolic extract of dried leaves of four medicinally important herbs Ocimum sanctum, Mentha spicata, Trigonella foenum-graecum, Spinacia oleracea utilized in our routine diet along with one medicinal important tree Gmelina arborea. Qualitative analysis of phytochemical constituents’ v...

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...

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 (...

BACKGROUND Recently, there has been an increased interest in the effects of essential oils on athletic performances and other physiological effects. This study aimed to assess the effects of Citrus sinensis flower and Mentha spicata leaves essential oils inhalation in two different groups of athlete male students on their exercise performance and lung function. METHODS Twenty physical educati...

BACKGROUND The aim of the present study was to appraise variation in the chemical composition, and antimicrobial and cytotoxic activities of essential oils from the leaves of four Mentha species-M. arvensis, M. piperita, M. longifolia and M. spicata-as affected by harvesting season. Disc diffusion and broth microdilution susceptibility assays were used to evaluate the antimicrobial activity of ...

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...
