The volatile components of kuromoji oil (Lindera umbellata Thunb.) obtained in Shizuoka Pref. were analyzed by GC/MS. Linalool, α-pinene, limonene, camphene, cis- and trans-dihydrocarvone, 1,8-cineol, 4-terpinenol, α-terpineol, piperitone, geranyl acetate, geraniol, and trans-nerolidol were identified as major components. Using enantio-MDGC-MS, the enantiomeric ratio ((R)-(-) vs (S)-(+)) of linalool in this oil was determined to be 67.8/32.2. Touch care treatment while sniffing this oil was done on cancer patients. We found that the relaxation effect persisted longer after the treatment compared to treatment without aroma. In the experiment, the researchers used many compounds, for example, Isopentyl 3-methylbutanoate (cas: 659-70-1HPLC of Formula: 659-70-1).
Isopentyl 3-methylbutanoate (cas: 659-70-1) 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.HPLC of Formula: 659-70-1
