“…It was previously suggested that mono- and sesquiterpenes present in the EO were responsible for the EO antimicrobial, but also herbicidal, antioxidant and anti-inflammatory activities [ 20 , 34 , 38 , 66 ]. As an example, linalool is often brought forward as the main explanatory factor of the EO activity [ 34 ].…”

The potential of essential oils (EO), distilled from two aromatic plants—clary sage (Salvia sclarea L.) and coriander (Coriandrum sativum L.)—in view of applications as natural therapeutic agents was evaluated in vitro. These two were cultivated on a trace element (TE)-polluted soil, as part of a phytomanagement approach, with the addition of a mycorrhizal inoculant, evaluated for its contribution regarding plant establishment, growth, and biomass production. The evaluation of EO as an antioxidant and anti-inflammatory, with considerations regarding the potential influence of the TE-pollution and of the mycorrhizal inoculation on the EO chemical compositions, were the key focuses. Besides, to overcome EO bioavailability and target accession issues, the encapsulation of EO in β-cyclodextrin (β-CD) was also assessed. Firstly, clary sage EO was characterized by high proportions of linalyl acetate (51–63%) and linalool (10–17%), coriander seeds EO by a high proportion of linalool (75–83%) and lesser relative amounts of γ-terpinene (6–9%) and α-pinene (3–5%) and coriander aerial parts EO by 2-decenal (38–51%) and linalool (22–39%). EO chemical compositions were unaffected by both soil pollution and mycorrhizal inoculation. Of the three tested EO, the one from aerial parts of coriander displayed the most significant biological effects, especially regarding anti-inflammatory potential. Furthermore, all tested EO exerted promising antioxidant effects (IC50 values ranging from 9 to 38 g L−1). However, EO encapsulation in β-CD did not show a significant improvement of EO biological properties in these experimental conditions. These findings suggest that marginal lands polluted by TE could be used for the production of EO displaying faithful chemical compositions and valuable biological activities, with a non-food perspective.

“…For the phytotoxic activity test, different studies have reported that some essential oils and their components are potent inhibitors of seed germination and retard plant growth [ 40 ]. Germination and seedling growth bioassays are important preliminary screening methods to determine phytotoxic potential of plant extracts and compounds [ 41 ]. E. cardamomum , A. corriroma and A. subulatum essentials oils have been recognized for their wide range of physiological and pharmacological properties but no studies were carried out on their phytotoxic activities.…”

To highlight the importance of the spices in the Mediterranean diet, the aim of the paper was to study the essential oil compositions and to clarify the potential differences in the biological activities of the three cardamom species. In the study, we compared the phytochemical profiles and biological activities of essential oils from Elettaria cardamomum, Aframomum corrorima and Amomum subulatum. The oils were analyzed using the GC and GC/MS techniques and were mainly constituted of the oxygenated monoterpenes which represents 71.4%, 63.0%, and 51.0% of all compounds detected in E. cardamomum, A. corrorima and A. subulatum essential oils, respectively, 1,8-cineole was the main common compound between the tree tested volatile oil. The essential oils showed significant antimicrobial activity against Gram-positive and Gram-negative microorganisms tested especially the fungal strains. The Ethiopian cardamom was the most active essential oil with fungal growth inhibition zone ranging from 12.67 to 34.33 mm, MICs values ranging from 0.048 to 0.19 mg/mL, and MBCs values from 0.19 to 1.75 mg/mL. The three tested essential oils and their main component (1,8-cineole) significantly increased the production of elastase and protease production, and motility in P. aeruginosa PAO1 in a dose dependent manner. In fact, at 10 mg/mL concentration, the three essential oils showed more than 50% of inhibition of elastolytic and proteolytic activities in P. aeruginosa PAO1. The same oils inhibited also the violacein production in C. violaceum strain. It was also noticed that at high concentrations, the A. corrorima essential oil significantly inhibited the germination of radish. A thorough knowledge of the biological and safety profiles of essential oils can produce applications of economic importance.

“…Geraniol was prepared with a series of concentrations from 0, 2.5, 5, 10 and 20 % (diluted using 0.05% Tween 20 w/v) (Choi et al 2015). Each concentration of geraniol was applied evenly onto the soil surface by using a micropipette one day after 20 seeds of each bioassay species were sown.…”

“…There are many studies demonstrating the use of herbicide-treated organic mulches for weed control in nurseries (Mathers, 2003), but to date, there are limited studies focussing on the potential of oxygenated monoterpene like geraniol, when combined with organic mulch, for weed control. A previous study has shown that geraniol inhibited the growth of Aeschynomene indica and Abutilon theophrasti (Choi et al 2015). Although there are many studies investigating the exploitation of crop residue mulches for weed suppression (Dilipkumar et al 2015), there is scanty research investigating the potential of lemongrass leaf mulch for weed control.…”

Hand weeding continues to be one of the most laborious aspects of nursery maintenance. Oxygenated monoterpene, an important group of secondary metabolite found in essential oils, has a potential herbicidal activity that could be exploited as natural herbicide whereas organic mulch could delay weed emergence. Thus, this study aimed to examine the phytotoxicity of geraniol, an oxygenated monoterpene compound, in combination with lemongrass leaf mulch against three common weeds, Eleusine indica (grass), Cyperus distans (sedge), and Tridax procumbens (broadleaf). Greenhouse experiments were carried out by treating 4.0 t/ha lemongrass leaf mulch with 7.5% (v/v) geraniol compound. The pretreated mulch acted synergistically and inhibited the emergence and shoot growth of T. procumbens completely. However, the pretreated mulch exhibited a moderate inhibitory effect on C. distans emergence and growth. Geraniol-treated lemongrass leaf mulch acted synergistically and inhibited the emergence of E. indica by 72%, but it acted antagonistically and caused a 45% reduction of shoot biomass. The present findings suggest that geraniol-treated lemongrass leaf mulch has potent herbicidal activity but its phytotoxic effect is species-dependent.
