Influence of six essential oils on invasive Solidago canadensis L. seed germination

Abstract

Solidago canadensis L. (canadian goldenrod) is a very dangerous plant-invader in Europe, which tend to suppress the indigenous flora. Different methods have been reported to combat the weeds but often are harmful for human health as well as for environment. New strategies instead are based on the use of natural compounds. The potential phytotoxic effects of six EOs of sage (Salvia officinalis L.), peppermint (Mentha×piperita L.), oregano (Origanum vulgare L.) which belongs to family Lamiaceae and fennel (Foeniculum vulgare Mill.), dill (Anethum graveolens L.) and anise (Pimpinella anisum L.) which belongs to family Apiaceae, and of ten of their main constituents (anethole, anisole, camphor, carvone, estragole, limonene, menthol, menthone, thujon and thymol) were evaluated against canadian goldenrod seed germination. Only one EO was active against seed germination. The single components resulted more active in inhibiting seed germination. Phenolic compounds were the most inhibitory, followed by oxygenated monoterpenes and monoterpene hydrocarbons.

“…O. vulgare EO shows a significant inhibitory effect on Solidago canadensis seeds germination in a study where other EOs are ineffective, and significant differences were noted by using different concentrations of single components. [208] The EO's chemical composition is affected by plant phenological stages so their biological activity, including phytotoxicity, could be influenced by this factor as stated by Alipour and Saharkhiz in their study on R. officinalis. [209] The encapsulation on a starch matrix of R. officinalis EO for phytotoxic purposes has been reported for the first time very recently by Alipour et al, [210] in a study on inhibition effects against Amaranthus retroflexus and Raphanus sativus under greenhouse conditions.…”

“…Although the results are promising about the EOs use as alternative herbicides, the authors propose further studies are required to determine the cost, applicability, safety and phytotoxicity against the cultivated plants.

Chemical Composition and Antimicrobial Activity of the Essential Oil From Euphorbia helioscopia L.

“…21 trans-Dihydrocarvone is a common compound in the essential oils from some plants of the family Lamiaceae, including Mentha dumetorum, Mentha longifolia, Salvia officinalis, Origanum vulgare, and Thymus citriodorus, and some in the family Apiaceae, including Cuminum cyminum and Anethum graveolens. [22][23][24][25][26][27][28] The content of transdihydrocarvone in these 2 families is 0.03%-12.78% and 3.20%-31.11%. In addition, transdihydrocarvone (15.3%-51.2%) is the main compound in all developmental stages of Poiretia latifolia of the family Fabaceae from South America.…”

“…Different activities of Origanum spp. such as antioxidant (Dutra et al, 2019), cytotoxic (Coccimiglio et al, 2016), antimicrobial (Lesjak et al, 2016;Reyes-Jurado et al, 2019), anti-acetylcholinesterase (Abou-Taleb et al, 2016;Hajlaoui et al, 2016;López et al, 2018), antibacterial (da Cunha et al, 2018;Wijesundara & Rupasinghe, 2018), repellent (Govindarajan et al, 2016;La Pergola et al, 2017;Giatropoulos et al, 2018), antifungal (Vinciguerra et al, 2018), allelopathic (Boukaew et al, 2017), phytotoxic (Ibáñez & Blázquez, 2018;Grul'ová et al, 2019) insecticidal (Kim et al, 2016;Szczepanik et al, 2018;Benelli et al, 2019) have been determined in a number of studies.…”
