“…The concentration of the hydrolate will need to be adjusted in order to obtain good antimicrobial activity with minimal effect on parasitoid development. Standardization will also be addressed, one of the main problems related with the use of essential oils and hydrolates (Khater, 2013; Di Vito et al, 2019). Our work demonstrated that these compounds deserve attention as antimicrobial agents in insect media.…”

“…Among the Lamiaceae, Monarda fistulosa L. (wild bergamot) and other Monarda plants, indigenous to North America, have a long history of use as medicinal plants by Native Americans and are also cultivated in Europe (Hitchmough et al, 2004). Previous studies have shown high activity of essential oils and hydrolates of M. fistulosa against pathogenic microorganisms for humans and plants (Minardi et al, 2016;Di Vito et al, 2019). To the best of our knowledge, however, no essential oil or hydrolate (including those obtained from Lamiaceae plants) has ever been utilized to control contamination by microorganisms in insect media in replacement of conventional antimicrobial agents, such as gentamicin.…”

“…Essential oils, which are secondary metabolites produced naturally in various plant organs, have great potential as antimicrobial agents due to the presence of various types of aldehydes, phenolic compounds, and terpenes (Okoh et al, 2010). Hydrolates, which result as co‐products from steam distillation of essential oils, have also been found to exert significant antimicrobial activity (Prusinowska et al, 2016; Di Vito et al, 2019). Essential oils and hydrolates mainly derive from aromatic plants, including those of the Lamiaceae family (Isman, 2000).…”

Exorista larvarum (L.) (Diptera: Tachinidae), a larval parasitoid of Lepidoptera, can be reared from egg to fecund adult on artificial media composed of crude components. The standard in vitro culture is performed in 24-well plastic rearing plates. Exorista larvarum eggs, removed from superparasitized larvae of Galleria mellonella (L.) (Lepidoptera: Pyralidae), are individually placed in the wells, each containing a cotton swab soaked in liquid medium. The plates are then sealed until parasitoid puparium formation. To avoid contamination by microorganisms, the artificial medium is routinely supplemented with 0.01% solution of gentamicin. Experiments were carried out to assess whether this broadspectrum antibiotic may be replaced with hydrolate of Monarda fistulosa L. (Lamiaceae), which was selected due to its high in vitro activity against pathogenic microorganisms for humans and plants. The hydrolate was either supplemented to the artificial medium (0.5% wt/wt) (first experiment) or placed in an empty well (200 ll) of the rearing plate, to be supplied as saturated air due to evaporation (second experiment). In both experiments, a standard medium with gentamicin and an antimicrobialfree medium were maintained as positive and negative controls, respectively. In the first experiment, in the hydrolate-supplemented medium fewer E. larvarum completed egg-to-adult development than in the standard medium, but significantly more parasitoids developed from egg to adult compared to the antimicrobial-free medium. No significant difference was found between the numbers of eggs laid by the females obtained from the standard medium vs. those from the hydrolate-supplemented medium. In the second experiment, the hydrolate-saturated air significantly decreased E. larvarum egg hatching, puparium formation, and female fecundity compared to the standard medium. In perspective, M. fistulosa hydrolate supplemented to the artificial media for E. larvarum may be considered as a promising candidate to replace the gentamicin solution, as suggested also by the microbiological analyses of the media, performed at various growth stages of the parasitoid in a separate trial. Conversely, the hydrolate-saturated air treatment was deemed unsuitable.

“…This means a higher hydro-late effectiveness that is likely to occur due to the hydrophilic environment promoting a higher terpene availability. Lastly, hydrolate exhibited promising results in the control of fungal growth on paper artwork, suppressing the four tested strains at concentrations of 25-50% [32]. The plant part [51] or date of harvest [20], processing plant material (fresh or dry) [47], as well as the extraction method [20], or formulations such as nanoemulsion [28], also influence the chemical composition and further antimicrobial properties.…”

Hydrolates, also referred to as hydrosols, floral or distillate waters, as well as aromatic waters, are produced in the same isolation process with essential oils by steam distillation. A small amount of essential oil constituents is dissolved in hydrolates providing specific organoleptic properties and flavor, as well as biological activity which makes them useful as raw material in many industries. Their popularity is still on the rise, especially in aromatherapy. The objective in this review is to analyze the chemical compositions of hydrolates and their corresponding essential oils, as well as biological activity of hydrolates (antimicrobial, antioxidant and antiinflamatory) and potential uses, not only in food industry for flavoring, and preservation of fresh-cut fruits and vegetables, but also as functional (soft) drinks. However, hydrolates can be used in aromatherapy and cosmetics, as well as in organic agriculture and aquaculture.

“…Essential oils of Monarda species have been reported to be rich in oxygenated monoterpenes, leading to differentiation into the following chemotypes: thymol, carvacrol, borneol, and geraniol [ 10 ].

Essential Oils from Monarda fistulosa: Chemical Composition and Activation of Transient Receptor Potential A1 (TRPA1) Channels

et al. 2020

Little is known about the pharmacological activity of Monarda fistulosa L. essential oils. To address this issue, we isolated essential oils from the flowers and leaves of M. fistulosa and analyzed their chemical composition. We also analyzed the pharmacological effects of M. fistulosa essential oils on transient receptor potential (TRP) channel activity, as these channels are known targets of various essential oil constituents. Flower (MEOFl) and leaf (MEOLv) essential oils were comprised mainly of monoterpenes (43.1% and 21.1%) and oxygenated monoterpenes (54.8% and 77.7%), respectively, with a high abundance of monoterpene hydrocarbons, including p-cymene, γ-terpinene, α-terpinene, and α-thujene. Major oxygenated monoterpenes of MEOFl and MEOLv included carvacrol and thymol. Both MEOFl and MEOLv stimulated a transient increase in intracellular free Ca2+ concentration ([Ca2+]i) in TRPA1 but not in TRPV1 or TRPV4-transfected cells, with MEOLv being much more effective than MEOFl. Furthermore, the pure monoterpenes carvacrol, thymol, and β-myrcene activated TRPA1 but not the TRPV1 or TRPV4 channels, suggesting that these compounds represented the TRPA1-activating components of M. fistulosa essential oils. The transient increase in [Ca2+]i induced by MEOFl/MEOLv, carvacrol, β-myrcene, and thymol in TRPA1-transfected cells was blocked by a selective TRPA1 antagonist, HC-030031. Although carvacrol and thymol have been reported previously to activate the TRPA1 channels, this is the first report to show that β-myrcene is also a TRPA1 channel agonist. Finally, molecular modeling studies showed a substantial similarity between the docking poses of carvacrol, thymol, and β-myrcene in the binding site of human TRPA1. Thus, our results provide a cellular and molecular basis to explain at least part of the therapeutic properties of these essential oils, laying the foundation for prospective pharmacological studies involving TRP ion channels.
