The objective of the present study was to investigate the chem. composition of the essential oil from Cirsium setidens. C. setidens (koryoungungqwui in Korea) is a perennial plant belonging to the Compositae family, and it is an endemic species of Korea. The essential oil obtained by hydrodistillation Clevenger method from the aerial part of C. setidens was analyzed by GC and GC-MS. Ninety-two volatile flavor components, constituting 94.0 % of the total volatile composition of the essential oil, were identified in the essential oil of C. setidens. The oil was composed mainly of alcs., ketones, esters, terpenes, carboxylic acid and hydrocarbons. Phytol (38.67 %) was the most abundant compound, followed by 6,10,14-trimethyl-2-pentadecanone (16.74 %), hexadecanoic acid (8.37 %), 1,2,15,16-diepoxyhexadecane (2.30 %), and β-caryophyllene alc. (2.28 %). This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Related Products of 5444-75-7).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C 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.
