  • Compositions of essential oils extracted from mint herb such as Mentha piperita, Mentha spicata, and Mentha ${\times}$ piperita var. citrate produced in Jeju were analyzed using gas chromatography-mass spectrometry (GC-MS) and headspace-GC-MS (HS-GC-MS). By the GC-MS analysis, 13 compounds were tentatively identified in Mentha piperita, Mentha spicata, and Mentha ${\times}$ piperita var. citrate, respectively. Peperitenone oxide, carvone, and linalool were detected as major compounds in Mentha piperita, in Mentha spicata, in Mentha ${\times}$ piperita var. citrate, respectively, based on the ratio of peak intensity in the total ion chromatogram. The greater number of compounds, including volatile alcohols and acetates were identified by HS-GC-MsS than by GC-MS in these all three essential oils. Similar patterns of composition were detected in both Mentha spicata and Mentha ${\times}$ piperita var. citrate by either one of GC-MS methods. However, in case of Mentha piperita, $\small{L}$-(-)-menthol, which was identified as the major compound by HS-GC-MS was detected in dramatically reduced quantity by GC-MS. Interestingly, we found that both linalyl acetate and linalool were identified as the dominant compounds in the essential oil of Mentha ${\times}$ piperita var. citrate.

  • The trichomes on leaves of three species of Mentha such as M. spicata, M. suaveolens, and M. piperita var were examined by scanning electron microscopy. Simple non-glandular trichomes and peltate glandular trichomes were distinctively occurred on these leaves. In M. spicata, short and sharp non-glandular trichomes were dominantly appeared on adaxial surface, whereas capitate glandular trichomes were commonly localized on abaxial surface. In M. suaveolens, non-glandular trichomes were identified with simple unbranched and branched. Unbranched trichomes which were sharp and pointed in shape occurred on adaxial surface, however, branched and v-shaped trichomes appeared abundantly on abaxial surface. Peltate trichomes consisted of a large eight-celled head. Small capitates trichomes consisted of a cylindrical head with an one-celled uniseriate stalk. In M. piperita var, single non-glandular trichomes and peltate trichomes were present on adaxial surface. Small capitate trichomes consisted of a globose unicellular head with a two- or three-celled uniseriate stalk. Peltate trichomes were distinctly present on abaxial surface, whereas they were not observed on adaxial surface. The trichomes were less dense in this species. Peltate trichomes consisted of a large eight-celled head, with an enlarged secretory cavity, attached to an one-celled short stalk.

  • IPP isomerase (Iso) and Limonene synthase (Limo) are important enzymes in terpenoids biosynthesis pathway. The wild type and each metabolically engineered (Iso and Limo) transgenic spearmint (Mentha spicata Linne) plants were compared for their growth patterns and the contents of essential oil in in vitro culture media. The profile of terpenoid metabolites was obtained from the essential oil of the metabolically engineered transgenic spearmint, which was extracted using a modified SDE method, by GC-MS analysis. The growth of wild spearmint was more profuse in B5 culture medium than in other media. Significant differences in leaf and root growth patterns were observed between metabolically engineered transgenic and wild type spearmint plants. The leaves of the transgenic spearmint plants were slightly elongated but were dramatically narrower than those of wild type spearmints. The content of essential oil of transgenic spearmint was different slightly depending on the target terpenoid genes. The content of essential oils in Limo transgenic plants was higher than that of Iso, except for transgenic plant in B5 medium. The transgenic spearmint produced more terpenoids than the wild type. Iso spearmint extracts showed eleven terpenoids and a phenylpropane, while Limo spearmint extracts contained nine terpenoids. However, extracts from the wild type showed the presence of only four terpenoids.

  • Forest tree species usually takes for long periods to be harvested and cultivated but spearmints are a good model system for woody plant because of reducing and shortening cultivation time. Spearmints are good model plants (Mentha species) for research about terpenoids production and industrial essential oil manufacture. Isopentenyl pyrophosphate isomerase (Iso) and limonene synthase (Limo) are the key enzymes of terpenoid biosynthesis pathway. Transgenic and wild spearmints (Mentha spicata, MS) were cultured in vitro and assessed for the essential oil contents. The content of essential oil of transgenic spearmint also was enhanced slightly depending on the target terpenoid genes. In an attempt to increase productivity of terpenoids further, salt and fungal elicitation strategy was adopted on transgenic Mentha spicata. The salt (800 mM NaCl) as abiotic and two fungi (Botrytis cinerea and Glomerella cingulata) as biotic were used for elicitors. In the absence of salt stress four terpenoids were detected from the spearmint extracts, all of them being monoterpenes. On the other hand, the transgenic (MSIso) extracts contained eleven terpenoids (10 monoterpenes and 1 phenylpropene) while transgenic (MSLimo) extracts contained seven monoterpenes. After 3 days of fungal infection, the resistance indices further increased to 4.38, 3.89 and 2.04 for wild type, MSIso and MSLimo, respectively. The salt and fungal elicitators proved beneficial towards modifying both the terpenoids profile and improvement in the composition of essential oil. These results have important applications for the large-scale production of essential oils and forest biotechnology with respect to spearmint.

  • This study investigated the effects of NaCl and jasmonic acid (JA) on the growth and physiological responses of spearmint (Mentha spicata L.). Spearmint was hydroponically grown for 3 weeks in modified Hoagland solution containing 0 (untreated control), JA ($20{\mu}M$ JA pretreatment), NaCl (50 mM NaCl treatment) and JA + NaCl ($20{\mu}M$ JA pretreatment + 50 mM NaCl treatment). Growth characteristics, chlorophyll, vitamin C, proline contents, DPPH scavenging activity and inorganic ion contents were evaluated. As a results, there were significant decreases in the plant height, leaf length, leaf width, and fresh weight of plants, treated with NaCl compared with control. On the other hand, the dry matters of shoot and root treated with JA + NaCl combination were better than control or NaCl treatment. Chlorophyll a and b contents in JA treatment was the highest. Vitamin C, antioxidant activity, and proline content in shoot were increased in NaCl treatment which showed low level of growth rate. The K/Na ratio, which is known to indirectly reflect the balance of ion uptake, was higher in a single treatment of JA than the control group, while lower in salt treatment (NaCl and JA + NaCl) because of high $Na^+$ absorption. In conclusion, these results showed that moderate stress treatment such as low level salt treatment and plant growth regulator jasmonic acid (JA) application would be potential strategies to improve the quality of spearmint by inducing the accumulation of secondary metabolites containing high antioxidant activity and essential oil.

  • Repellencies of herb plants and essential oils against alate Myzus persicae were investigated in a insect cage, a screen house, and a tobacco field. Numbers of nymphs deposited by alate or apterous Myzur persicae were lower on rosemary(Rosmarinus officinalis), silver thyme (Thymus vulgaris), and lemon balm(Melissa of fcianazis). Rosemary and silver thyme show little repellency against alate Myzus persicae on a nearby tobacco plant Rosemary oil, peppermint (Mentha piperita) oil, and ginger oil showed repellency against alate Myzus persicae, but spearmint (Mentha spicata) oil and lavender oil showed little repellency in a screen house. Rosemary oil, ginger oil, peppermint oil, lavender oil, and spearmint oil showed repellency against alate Myzus persicae in a tobacco field, but there was no significant difference among oils.

  • For selecting a new candidate as functional material, this study was conducted on in vitro antioxidant activity and total phenol content of methanol and water extracts prepared from two Mentha species (M viridis L. (M spicata L.) and Mentha piperita L, Extracts of M. viridis showed more efficient scavenging activity on superoxide and DPPH ${({\alpha},{\alpha}-diphenyl-{\beta}-picrylhydrazyl)}$ radical and inhibitory activity on oxidation of human low density lipoprotein (LDL) induced by $CuSO_4$ and auto-oxidation of linoleic acid than those of M piprita. Methanol extract $(65.88%{\sim}77.59%)$ and water extract $(37.69%{\sim}87.21%)$ of M. viridis also exhibited more potent inhibitory activity on LDL oxidation than that of ${{\alpha}-tocopherol\;(28.37%{\sim}66.54%)}$ at ${1{\sim}100\;{\mu}g/ml}$ of final concentration. The total phenol contents of methanol extract and water extract of Mviridis (17.95% & 10.18%, respectively) as tannic acid equivalent were higher than those of M piperita (15.44% & 9.19%). But the yields of methanol and water extracts of M. viridis (13.3 % & 13.5%) were lower than those of M. piperita (14.1 % & 14.6%). The results implies that the extracts from M. viridis (spicata) is more useful material for industrialization as functional food than those from M. piperita.

  • This study was carried out in order to investigate of effects of environmental conditions which influence negative ions development. Negative ions are nature' most powerful air-cleaning agents, are created by nature, and found at their most optimal levels where the air is most pure and healthy. Negative ions are regarded as one of the important factors which indicate the quality of the air. Therefore, the focus of this study was to clear relationship among negative ions development induced by plant cultivar and environmental conditions such as air temperature, light intensity and relative humidity. As the results of this study, it was found that negative ions development was promoted during the period with plants compared to the period without plants. In Particular, negative ions development was high under air temperature $20^{\circ}C$, relative humidity 90% and dark condition. Temperature and humidity factors on this experiment was strongly affected on negative ions development, but light intensity had almost slight effect. It was shown that these results can contribute to the application of environmental control techniques to negative ions. Among plant cultivar of Spathiphyllum spp. Mentha spicata, and Cupressu arizonica, Mentha spicata was higher negative ions than the other plants, and also the leaves were higher than the stems and roots. The effect of plants on the perception of the inte끼r air quality may, therefore, be one explanation of this results about negative ions. on the other hand, it seems that a green indoor environment might be an increase in general well-being due to the plants.

  • The purpose of this study was to figure out the best condition in growth and sod quality of Mentha spp. according to cutting methods and soil depth. Applemint (M. suaveolens), Peppermint (M. piperita), and Spearmint (M. spicata) were used. Regardless of cultivar and soil depth condition, the growth rate in top cutting was higher than layering method. The difference between layering and layering without apical meristem was not significant. Optimal condition for growth was 5cm depth of soil. However, the shallower the depth of the soil, the better quality of sod. Among three Mentha species, M suavelens showed plant height and node number and M. piperita had shoot number were higher than other variety. The best condition of sod was top cutting and 1cm depth of soil regardless of cultivar.
