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).
