“…A further experiment from Poland reported higher neral and geranial levels under higher insolation [ 22 ]. In pot experiments, soil water content hardly influenced essential oil composition [ 24 ]. On the other hand, various accessions cultivated on two different sites in Turkey clearly differed in their oil composition [ 25 ].…”

Phytochemical characters were evaluated in a five-year-old lemon balm collection consisting of 15 and 13 subspecies officinalis and altissima accessions, respectively. Stems were lower in essential oil than leaves. First cut leaves (June) gave more oil than those of the second cut (August). Subspecies officinalis plants had leaf oils rich in geranial, neral and citronellal in various proportions in the first cut. However, in the second cut the oils from all accessions appeared very similar with 80–90% geranial plus neral. Leaf oils of subsp. altissima contained sesquiterpenes (β-caryophyllene, caryophyllene oxide, germacrene D) and also further monoterpenes in the second cut. Leaves had higher rosmarinic acid (RA) contents than stems. More RA was in subsp. officinalis than subsp. altissima leaves. First cut leaves were richer in RA than those from second cut. Total phenolics and antioxidant parameters showed that lemon balm is a valuable source of plant antioxidants.

“…The content of EO increased at 20 mg kg −1 Ni, after that the content starts to decline up to the highest concentration of Ni (100 mg kg −1 of soil) ( Table 4). The secondary metabolites (such as EO) are secreted during the stress conditions in plants (Bahreininejad et al 2014;Németh-Zámbori et al 2016;Del Carman Sosa et al 2016). The escalation in the EO content of M. arvensis at 20 mg kg −1 Ni might be due to alterations in the morphology and number of trichomes on plant leaves.…”

Alterations in photosynthetic pigments, antioxidant machinery, essential oil constituents and growth of menthol mint (Mentha arvensis L.) upon nickel exposure

The present study was conducted in view of the alarming increase in the concentration of various heavy metals like nickel, copper, lead, cadmium, and arsenic etc., in the soils globally. Little attention has been paid towards the deleterious effect of these heavy metals particularly nickel (Ni) on the performance of pharmaceutically exigent essential oil-bearing crops like menthol mint (Mentha arvensis L.). Menthol mint, a dominant essential oil-producing aromatic plant, is widely cultivated in Uttar Pradesh (India) and has wide applications in pharmaceutical industry. Nickel, an essential micronutrient and a main component of the plant enzyme urease, has vital role in plants and is required in very low amounts for normal growth and functioning of plants. In this study, Ni was applied in the form of NiCl 2 with various concentrations of 20, 40, 60, 80, and 100 mg kg −1 Ni of soil and one set was kept as control. Interestingly, Ni at 20 mg kg −1 of soil significantly enhanced all the parameters studied, including constituents of essential oil, particularly menthone and menthyl acetate content. However, a significant reduction was observed in most of the parameters studied with increasing concentrations of Ni. The growth (plant height, fresh and dry weights and herbage yield), biochemical (photosynthetic pigments, chlorophyll fluorescence and carbonic anhydrase activity), and quality parameters (content of essential oil & its active constituents) exhibited a significant reduction over 20 mg kg −1 of soil. However, the activities of enzymatic antioxidants, such as superoxide dismutase (SOD), catalase (CAT), and peroxidase (POX), and the level of proline (PRO) were enhanced at the higher concentrations of Ni. Thus, the present study confirms that Ni applied at 20 mg kg −1 of soil proved beneficial dose, whereas 100 mg kg −1 of soil produced toxic response for the overall growth and development of the mint crop.

“…Secondary metabolites are substances that give plants various advantages in important events such as defense, protection, survival and reproduction that helps them to adapt to the environmental conditions in the ecosystem (Bourgaud et al, 2001). Thus, the amount of these substances per unit increases under stress conditions (Haddadi et al, 2016;Németh-Zámbori et al, 2016). However, stress factors also cause deformations in various growth parameters of plants leading to a decrease in the production of metabolites (Saeidnejad et al, 2016).…”

“…Quantities of linalool, citronellal, geraniol, citral (neral and geranial) and β-caryophyllene-oxide in lemon balm's essential oil content (Pereira et al, 2014) can vary between different development stages or different organs of the same plant (Moradkhani et al, 2010). They also show significant variance under stress conditions such as drought, salinity, etc (Farahani et al, 2009;Németh-Zámbori et al, 2016). The aim of this study was to determine how lemon balm responded to increasing Cd concentrations in terms of changes in (1) vegetative growth, (2) stomata and epidermis counts, stomata size, and stomata index of both surfaces of leaves, (3) leaf surface area, (4) total chlorophyll content, and (5) accumulation of EO.…”

Abstract. Secondary metabolites, which have an important role in regulating plants' relationship with the environment, are affected by soil pollution. Thus, it is important to describe the mechanism in which lemon balm's (Melissa officinalis L. subsp. officinalis) secondary metabolite accumulation is affected by Cadmium (Cd) stress. For this purpose, lemon balms seedlings that were grown in a controlled environment were exposed to increasing Cd stress and the relationship of lemon balm's growth and development with EO (essential oil) accumulation were investigated. Morphological, anatomical and physiological parameters of plants' that were exposed to Cd significantly decreased in parallel with increasing Cd concentration. Impairments in growth and development of lemon balm due to increasing Cd concentrations also affected EO accumulation. However, this destructive effect was most evident on EO accumulation amongst all investigated parameters. Furthermore, amount of EO decreased by 97%, at the highest concentration. In conclusion, Cd might have damaged both the EO producing mechanism and the structures that produce EO by inhibiting plant growth. Therefore it is important to reveal the responses of all parameters which affect EO production of medicinal plants under various stress conditions.
