Chemical constituents of essential oil from Smilax glabra Roxb was written by Cao, Zhengzhong;Yi, Yijun;Cao, Yuan;Yang, Dalong. And the article was included in Tianran Chanwu Yanjiu Yu Kaifa in 1994.Name: Ethyl methyl adipate The following contents are mentioned in the article:
The chem. constituents of essential oil of root for S. glabra which are obtained from LAKXI were isolated by means of GC-MS method. Forty-seven compounds were identified. The main components of essential oil were long-chain aliphatic esters. This study involved multiple reactions and reactants, such as Ethyl methyl adipate (cas: 18891-13-9Name: Ethyl methyl adipate).
Ethyl methyl adipate (cas: 18891-13-9) 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.Name: Ethyl methyl adipate
