Production of beta ionone
Webb20 dec. 2014 · The chemical production process of β-ionone involves base-catalyzed condensation from citral to linear pseudoionones, followed by acid-catalyzed cyclization ( OECD, 2004 ). The resulting ionone cannot be marketed as a natural product, but rather must be labelled as being “nature identical”. WebbThis article is cited by 13 publications. Madhvanand N.

Webb2 juni 1994 · A process is described for the manufacture of .beta.-ionone by the sulphuric acid-catalyzed cyclization of pseudoionone in a two-phase solvent system comprising concentrated sulphuric acid and a second solvent essentially immiscible with water, which process comprises using carbon dioxide liquefied under pressure as the second solvent. WebbThe study showed that β-ionone is mainly involved in the reduction of cell proliferation and regulation of HMG-CoA reductase activity [19], thus defining β-ionone as the biologically active chemopreventive agent.
