General description

α-Ionone is one of the key volatile constituents of the oil from whitefly (Syngonium podophyllum Schott).

Application


  • Dietary supplementation with α-ionone alleviates chronic UVB exposure-induced skin photoaging in mice.: This research demonstrates that α-ionone can mitigate the effects of chronic UVB exposure, reducing skin photoaging in mice. The findings suggest potential applications for α-ionone in skincare and dermatological products (Geng et al., 2024).

  • Re-Rolling Treatment in the Fermentation Process Improves the Aroma Quality of Black Tea.: This research shows that re-rolling treatment during fermentation enhances the aroma quality of black tea by increasing the concentration of volatile compounds, including α-ionone, which contribute to the tea′s overall flavor profile (Chen et al., 2023).

An efficient highly enantioselective (ee > or =99%) synthesis of alpha-ionone and alpha-damascone is described. Both enantiomers of title compounds were synthesized through two straightforward pathways diverging from enantiopure (R)- or (S)-alpha-cyclogeraniol. These versatile building blocks were obtained by regioselective
