The aim of this work was to study the chem. composition and antioxidant activity of essential oils of Thymus ciliatus (Desf.) Benth from middle Algeria obtained from the aerial parts by hydrodistillation using a Clevenger-type apparatus The oil was analyzed by gas chromatog. (GC) and gas chromatog. coupled with mass spectrometry (GC-MS). The antioxidant capacity values of T ciliatus extracts were determined using 2 different and complementary assays: free radical scavenging (2,2-diphenyl-1-picrylhydrazyl [DPPH]) and ferric reducing antioxidant power (FRAP) assays. Six samples of T ciliatus collected in 2019 were used in the study. GC and GC-MS were used to determine the chem. composition of the essential oils. Twenty-five compounds were identified with a percentage of 89.3%-97.7%. The essential oils of T ciliatus were characterized by the presence of myrcene (9.6%-26.9%), p-cymene (7.6%-17.0%), and borneol (13.4%-30.2%) as principal components. In the experiment, the researchers used many compounds, for example, (E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3Safety of (E)-3,7-Dimethylocta-2,6-dien-1-yl acetate).
(E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Safety of (E)-3,7-Dimethylocta-2,6-dien-1-yl acetate
