Characteristically appearing in their liquid, volatile, limpid and rarely colored form, essential oils also display a good solubility in lipids and organic solvents, often having lower densities than that of water [81]. Odorous secondary metabolite biosynthesis in Mentha species occurs in peltate glandular trichomes, specialized epidermal tissues located on leaves, stems, petals and seed coat surfaces, depending on the species [59,60].

Exhaustive studies have been made to understand the role of nitrogen (N), phosphorus (P) and potassium (K) requirements on herbage production and essential oil yield. Indeed, N application at 160 kg N/ha for M. arvensis, 125 kg N/ha for M. × piperita, 100–120 kg N/ha for M. aquatica and M. spicata give a higher dry matter amount and essential oil yield [48,49,50]. Helsel and Fluck [51] have shown a correlation between N fertilizer application and (−)-carvone and limonene concentrations in Mentha × gentilis L. Generally, 80–120 kg N fertilizer, 50 kg P.L.) was not officially described until 1696, when the English botanist John Ray (1628–1705) first discovered this pepper-flavored mint.

Entering the London Pharmacopoeia in 1721, peppermint has since been cultivated for its essential oil throughout Asia, Europe, and North America [4]. Mint history is colored by stories from ancient mythology. Proserpine, Pluto’s wife, was said to have transformed a hated rival into a mint plant. Both the Latin “mentha” and the Greek “minthe” have come to be associated with metamorphosed beauty [5].value by fumigant bioassay (Abbas and Javad, 2012). Halit et al. (2012) studied the fumigant effect of three essential oils of the genus Mentha such as M. spicata, M. villoso-nervata, and M. piperita against S. granarius. Among these M. villoso-nervata exhibited 90% mortality of adults by fumigant bioassay, while its main constituent carvone exhibited 100% mortality at 24 h of exposure with 0.024 μl/ml LC (Source: www.frontiersin.org)
