“…The variation in the essential oil composition of M. longifolia is reported in the literature from different part of the world [8, 17, 18]. Our results reported the essential oil composition of M. longifolia essential oil from South Punjab, Pakistan, where the weather conditions are very hot and dry.…”

The antioxidant activity and free radical scavenging capacity of the essential oil and three different extracts of wildly grown Mentha longifolia (M. longifolia) were studied. The essential oil from M. longifolia aerial parts was isolated by hydrodistillation technique using Clevenger-type apparatus. The extracts were prepared with three solvents of different polarity (n-hexane, dichloromethane, and methanol) using Soxhlet extractor. Maximum extract yield was obtained with methanol (12.6 g/100 g) while the minimum with dichloromethane (3.50 g/100 g). The essential oil content was found to be 1.07 g/100 g. A total of 19 constituents were identified in the M. longifolia oil using GC/MS. The main components detected were piperitenone oxide, piperitenone, germacrene D, borneol, and β-caryophyllene. The total phenolics (TP) and total flavonoids (TF) contents of the methanol extract of M. longifolia were found to be significantly higher than dichloromethane and hexane extracts. The dichloromethane and methanol extracts exhibited excellent antioxidant activity as assessed by 2,2′-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging ability, bleaching β-carotene, and inhibition of linoleic acid peroxidation assays. The essential oil and hexane extract showed comparatively weaker antioxidant and free radical scavenging activities. The results of the study have validated the medicinal and antioxidant potential of M. longifolia essential oil and extracts.

“…Our results extend this understanding in the way that harvesting season can also alter composition of M. arvensis, M. piperita and M. longifolia essential oil. There are some reports in the literature on the qualitative and quantitative analyses of some Mentha essential oils from different countries,1, 2, 22, 23 but we could not find a single report showing the seasonal variation on the essential oils composition and biological activity of these four Mentha species. Therefore the results are different from others and indicate that this study is by no means a repetition.…”

“…In two samples out of four (Nos 10 and 11, collected from the same place) rather high concentrations of germacrene D with α-muurolene, limonene with 1,8-cineole (samples 5, 10, and 12), and trans-β-caryophyllene (samples 10 and 11) and less trans-dihydrocarvone (samples 5 and 12) and piperitone (samples 10 and 11) were found. Other authors identified the mentofuran-rich (Viljoen et al, 2006), piperitone oxide-rich (Hussain et al, 2010a), cispiperitone oxide and piperitenone oxide-rich (Viljoen et al, 2006;Singh et al, 2008;Kakhky et al, 2009), menthone-rich (Asekun et al, 2007), menthone, menthol, and pulegone-rich (Hajlaoui et al, 2008), pulegone-rich (Mkaddem et al, 2009), carvone and limonene-rich, piperitenone oxide and 1,8-cineole-rich (Koliopoulos et al, 2010) chemotypes of M. longifolia. The oils of M. spicata contained much more myrcene (2.3-5.5%) than M. longifolia (0.6-0.9%).…”

The content and composition of essential oils in leaves of Mentha × piperita L., M. spicata L., M. arvensis L., and M. longifolia (L.) Huds. from Estonia were investigated using hydrodistillation and GC-MS analyses. Some chemosystematic markers for the identification of Mentha species are presented. The essential oil yield of the studied species was 2.4-3.0%, 0.9-2.3%, 0.9-1.4%, and 0.7-2.5%, respectively. From the isolated essential oils, 75, 89, 67, and 69 compounds were identified and quantitatively evaluated, representing 92.2-99.5% of the total oil. The main constituents of M. × piperita oils were menthol (26.4-47.7%) and menthone (13.6-31.9%); the ratio of their content was usually between 1 and 3. Four chemotypes of M. spicata were determined: rich in carvone (62.1-67.4%), rich in piperitenone oxide (61.9%), rich in α-terpinyl acetate + trans-β-caryophyllene (61.9% and 11.4%, respectively), and rich in acetic acid,1-methyl-1-(4-methyl-5-oxo-cyclohex-3-enyl) ethyl ether (6.5%). The last two chemotypes were determined for the first time. Only the essential oils of M. arvensis were found to contain trans-1-octen-3-ol (3.8-7.7%) and neryl propionate (2.4% in both samples). Good chemosystematic markers for M. arvensis were also trans-(16.0-19.1%) and cis-β-ocimene (16.0-20.5%). The ocimene-rich chemotype was found by us for the first time. The chemosystematics of M. longifolia was found to be the most complicated, as many chemotypes have been determined by us and several other authors. In this study, a high concentration of carvone (51.4-57.6%) was characteristic of all analysed M. longifolia samples.
