Many Eryngium species have been traditionally used as ornamental, edible or medicinal plants. The gas chromatog.-flame ionization detector (GC-FID) and gas chromatog.-mass spectrometry (GC-MS) analyses have shown that the major compounds in the aerial parts were spathulenol (in E. campestre and E. palmatum oils) and germacrene D (in E. amethystinum oil). The main compounds in the root oil were nonanoic acid, 2,3,4-trimethylbenzaldehyde and octanoic acid for E. campestre, E. amethystinum and E. palmatum, resp. All the oils expressed the highest potential against Gram-pos. bacteria Staphylococcus aureus as well as Gram-neg. Klebsiella pneumoniae and Proteus mirabilis. Mol. docking anal. was used for determining a potential antibacterial activity mechanism of compounds present in the essential oils. Mol. docking confirmed that the binding affinity of spathulenol to the active site of tyrosyl-tRNA synthetase was the highest among the tested dominant compounds Regarding the total phenolic content (determined by the Folin-Ciocalteu assay) and flavonoid content (evaluated using aluminum nitrate nonahydrate), the highest amount was found in the Et acetate extract of E. palmatum. The results of DPPH and ABTS assay indicated that the highest antioxidant activity was present in the water extract of E. amethystinum. Extracts of the aerial parts presented as min. inhibitory concentration (MIC) expressed the activity in the range 0.004-20.00 mg/mL, with the highest activity exhibited by the acetone and Et acetate extracts against Proteus mirabilis. The obtained results suggest that Eryngium species may be considered a beneficial native source of the compounds with antioxidant and antimicrobial properties. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Electric Literature of C15H22O2).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters contain a carbonyl center, which gives rise to 120掳 C鈥揅鈥揙 and O鈥揅鈥揙 angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C鈥揙鈥揅 bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
