“…By comparing our results with those obtained for glyphosate, used as a systemic herbicide in previous studies, and evaluated as a positive control in the present work, EO have demonstrated real potential. Indeed, previous studies have reported glyphosate's IC50 ranging from 23-46.2 mg L −1 [50] and 15.3 mg L −1 [51], regarding ryegrass growth inhibition, whereas the IC50 reported on lettuce ranged from 8.9 mg L −1 [52] to 20 mg L −1 [53]. The obtained IC50 for glyphosate in the present work are similar to those previously reported.…”

(1) Background: The use of natural products based on essential oils (EO) is nowadays arousing great interest as an alternative method to control plant pathogens and weeds. However, EO possess low bioavailability and are highly volatile, and their encapsulation in hydroxypropyl-ß-cyclodextrin (HP-β-CD) could be a means to enhance their stability and maintain their bioactivity. Thus, the current study aims at investigating, in the presence and the absence of HP-β-CD, the antifungal and phytotoxic activities of nine EO, distilled from plant species belonging to Alliaceae, Apiaceae, and Cupressaceae families, with considerations for their chemical composition. (2) Methods: EO antifungal activity was assessed by direct contact and volatility assays against Fusarium culmorum, a major phytopathogenic fungi, while phytotoxic effects were evaluated against lettuce (Lactuca sativa L.) and rye-grass (Lolium perenne L.), by seedling’s emergence and growth assays. (3) Results: These EO inhibit fungal growth in both direct contact and volatility assays, with half-maximal inhibitory concentrations (IC50) ranging from 0.01 to 4.2 g L−1, and from 0.08 up to 25.6 g L−1, respectively. Concerning phytotoxicity, these EO have shown great potential in inhibiting lettuce (IC50 ranging from 0.0008 up to 0.3 g L−1) and rye-grass (IC50 ranging from 0.01 to 0.8 g L−1) seedlings’ emergence and growth. However, the EO encapsulation in HP-β-CD has not shown a significant improvement in EO biological properties in our experimental conditions. (4) Conclusion: All tested EO present antifungal and phytotoxic activities, with diverse efficacy regarding their chemical composition, whilst no increase of their biological effects was observed with HP-β-CD.

“…In comparison with glyphosate, which is a systemic herbicide, and was evaluated as a positive control in this work, the tested EO displayed a consistent herbicidal activity. In previous studies, reported glyphosate IC 50 varied from 15.3 mg L −1 [70] to 23 and 46.2 mg L −1 [71] regarding the inhibition of ryegrass growth, while the results reported on lettuce ranged from 8.9 mg L −1 [72] to 20 mg L −1 [73], which are comparable to those obtained in this study. In addition, the EO from aerial parts of coriander, reported as the most efficient in terms of in vitro herbicidal activity, exerted effects similar to those of glyphosate, and even higher on rye-grass.…”

Owing to their various application fields and biological properties, natural products and essential oils (EO) in particular are nowadays attracting more attention as alternative methods to control plant pathogens and pests, weeds, and for post-harvest applications. Additionally, to overcome EO stability issues and low persistence of effects, EO encapsulation in β-cyclodextrin (β-CD) could represent a promising avenue. Thus, in this work, the EO distilled from two aromatic plants (Salvia sclarea L. and Coriandrum sativum L.) have been evaluated in vitro for their antifungal, herbicidal and insecticidal activities, against major plant pathogens and pests of agronomical importance. Both plants were grown on unpolluted and trace-element-polluted soils, so as to investigate the effect of the soil pollution on the EO compositions and biological effects. These EO are rich in oxygenated monoterpenes (clary sage and coriander seeds EO), or aliphatic aldehydes (coriander aerial parts EO), and were unaltered by the soil pollution. The tested EO successfully inhibited the growth of two phytopathogenic fungi, Zymoseptoria tritici and Fusarium culmorum, displaying IC50 ranging from 0.46 to 2.08 g L−1, while also exerting anti-germinative, herbicidal, repellent and fumigant effects. However, no improvement of the EO biological effects was observed in the presence of β-CD, under these in vitro experimental conditions. Among the tested EO, the one from aerial parts of coriander displayed the most significant antifungal and herbicidal effects, while the three of them exerted valuable broad-range insecticidal effects. As a whole, these findings suggest that EO produced on polluted areas can be of great interest to the agricultural area, given their faithful chemical compositions and valuable biological effects.

“…After the spectra interpretation, the EtOAc residue was applied to several chromatographic techniques, including Column Chromatography (CC) over silica gel and Sephadex LH-20, preparative-Thin Layer Chromatography (prep-TLC), to obtain 33 compounds. Subsequently, the present study unveiled one fatty acid derivative: triolein (1) [15], two diterpenoids: eubotriol (2) [4], siderol (3) [16], three iridoids: 8-epi-loganin (4) [17], ajugoside (5) [18], melittoside (6) [19], twelve flavonoid derivatives: kaempferol (7) [20], apigenin (8) (18) [26], two lignans: pinoresinol-4-O-β-D-glucopyranoside (19) [27], (7S, 8R)-urolignoside (20) [28], six phenylethanoid glycosides: trans-acteoside (21) [29], cis-acteoside (22) [30], trans-leucosceptoside A (23) [31], cis-leucosceptoside A (24) [32], martynoside (25) [33], lamalboside (26) [30] and seven phenolic acid derivatives: p-coumaric acid (27) [34], methyl trans p-coumarate (28) [35], 4-methoxybenzoic acid (29) [36], 4-hydroxybenzoic acid (30) [37], vanillic acid (31) [38], syringic acid (32) [39], benzyl-1-O-β-D-glucopyranoside (33) [40] (Table S1, Supplementary Materials). The chemical structures of all the isolated compounds were determined based on the interpretation of spectroscopic data (1D and 2D NMR), as well as on previous literature data.…”

In recent years, the use of Sideritis species as bioactive agents is increasing exponentially. The present study aimed to investigate the chemical constituents, as well as the anti-ageing potential of the cultivated Sideritis euboea Heldr. The chemical fingerprinting of the ethyl acetate residue of this plant was studied using 1D and 2D-NMR spectra. Isomeric compounds belonging to acylated flavone derivatives and phenylethanoid glycosides were detected in the early stage of the experimental process through 2D-NMR techniques. Overall, thirty-three known compounds were isolated and identified. Some of them are reported for the first time not only in S. euboea, but also in genus Sideritis L. The anti-ageing effect of the ethyl acetate residue and the isolated specialized products was assessed as anti-hyaluronidase activity. In silico docking simulation revealed the interactions of the isolated compounds with hyaluronidase. Furthermore, the in vitro study on the inhibition of hyaluronidase unveiled the potent inhibitory properties of ethyl acetate residue and apigenin 7-O-β-d-glucopyranoside. Though, the isomers of apigenin 7-O-p-coumaroyl-glucosides and also the 4′-methyl-hypolaetin 7-O-[6′′′-O-acetyl-β-d-allopyranosyl]-(1→2)-β-d-glucopyranoside exerted moderate hyaluronidase inhibition. This research represents the first study to report on the anti-hyaluronidase activity of Sideritis species, confirming its anti-inflammatory, cytotoxic and anti-ageing effects and its importance as an agent for cosmetic formulations as also anticancer potential.
