“…The Bray-Curtius percentage, selected as a measure of similarity and simple average, was used as the basis of cluster analysis. Earlier, on the basis of chemotaxonomic studies, M. spicata has been classified into carvone [6], piperetenone oxide [16], linalool [17], menthone/isomenthone [18], dihydrocarvone [19] and menthyl acetate types [20], but in the present study we could find only the carvone and piperetenone oxide types, along with two mixed populations (collections I and II), which contain both carvone and piperetenone oxide as the major compounds. This may be possible due to the hybrid nature of the plant.…”

The essential oils from fresh aerial parts of Mentha spicata L. collected from ten different natural habitats of Uttarakhand, India were analyzed by a combination of GC, GC/MS and NMR spectroscopy. The analysis revealed that monoterpenoids (46.1%-91.6%), mainly carvone (15.3%-68.5%), piperetenone oxide (24.0%-79.2%) and α-humulene (0.1%-29.9%), were the major constituents of the essential oils, but with significant qualitative and quantitative differences among the other constituents. Cluster analysis of the oil composition was carried out in order to discern the differences and similarities within different accessions collected from different natural habitats. The essential oils were also screened for their antioxidant activities by chelating properties of Fe 2+ , DPPH radical-scavenging activity, and their reducing power. The essential oils of two chemo variants (viz. carvone and piperetenone oxide types) were also tested for potato (Solanum tuberosum L.) sprout suppressant activity. The results showed that these oils exhibit good sprout inhibition activity in comparison to CIPC and iodine, the standard sprout suppressant.

“…The effects of nitrogen and phosphorus doses on all traits of spearmint genotypes were found to be significant (P < 0.01). Current findings comply with the findings of earlier studies indicating the effects of years, cultivars, ecology, fertilization, irrigation, harvest period, and genetic factors on spearmint essential oil composition (Misra et al, 1989;Özgüven and Kırıcı, 1999;Kirakosyan et al, 2004;Zobayed et al, 2005;Gopichand et al, 2013). The 1.8-cineole, 4-terpineol, and pulegone contents were higher in the second year than in the first year and such findings comply with the results of Kirakosyan et al (2004), proposing that cold weather or water stress might have increased polyphenolic compound contents.…”

IntroductionMedicinal and aromatic plants are effective with their active ingredients (Kamel, 2000). Several essential oils of such plants have antimicrobial, carminative, chlorotic, sedative, diuretic, and antispasmodic impacts in various diseases (Maksimovic et al., 2005). Peppermint cultivars contain menthone, isomenthone, carvone, and pulegone and all these peppermint essential oils have antimicrobial characteristics. They are also used as active ingredients in toothpastes, food stuffs, soaps, creams, lotions, and perfumes (Sivropoulou et al., 1995;Baydar, 2013).Nitrogen treatments are commonly used worldwide in plant culture to improve the yields (Ladha et al., 2005). Nitrogenous and phosphorus fertilizers may also improve essential oil yield and quality of medicinal and aromatic plants (

“…Although organoleptic evaluation of the oil of mutant 643 had suggested an abnormal composition, the analytical results were nevertheless surprising in that over 85% of the oil was composed of C3-oxygenated monoterpenes (Table I), of which well over half were 3-keto-1,2-oxides ( Fig. 1 M. cordifolia chemotypes (10,18), but the presence of these compounds and their C3-oxygenated congeners in spearmint types is unusual (17,22). A developmental study of oil compositional change as a function of leaf maturity of plants grown under controlled conditions indicated that the expansion of Scotch spearmint leaves from 0.5 cm to over 5 cm was accompanied by a gradual decrease in limonene content from over 20% to about 15%, with a gradual increase in carvone content from 50% to about 70%.…”

A radiation-induced mutant of Scotch spearmint (Mentha x graclis) was shown to produce an essential oil containing principally C3-oxygenated p-menthane monoterpenes that are typical of peppermint, instead of the CS-oxygenated monoterpene family characteristic of spearmint. In vitro measurement of all of the enzymes responsible for the production of both the C3-oxygenated and CS-oxygenated families of monoterpenes from the common precursor (-)-limonene indicated that a virtually identical complement of enzymes was present in wild type and mutant, with the exception of the microsomal, cytochrome P-450-dependent (-)-limonene hydroxylase; the C6-hydroxylase producing (-)-trans-carveol in the wild type had been replaced by a C3-hydroxylase producing (--trans-isopiperitenol in the mutant. Additionally, the mutant, but not the wild type, could carry out the cytochrome P-450-dependent epoxidation of the ai-unsaturated bond of the ketones formed via C3-hydroxylation. Although present in the wild type, the enzymes of the C3-pathway that convert trans-isopiperitenol to menthol isomers are synthetically inactive because of the absence of the key C3-oxygenated intermediate generated by hydroxylation of limonene. These results, which clarify the origins of the C3-and CS-oxygenation patterns, also allow correction of a number of earlier biogenetic proposals for the formation of monoterpenes in Mentha.The monoterpene constituents of the essential oils of peppermint (Mentha piperita L.) and spearmint (native = Mentha spicata L.; Scotch = Mentha x gracilis [28]) are distinguished by the position of oxygenation on the p-menthane ring3 (18,25). Peppermint produces almost exclusively monoterpenes bearing an oxygen function at C3, such as menthone and menthol, whereas spearmint species produce almost exclusively monoterpenes bearing an oxygen function at C6, typi-
