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).

Apparent binding constants of aroma compounds limonene, alpha- and beta-ionone, and terpenyl acetate, with beta-lactoglobulin (BLG), were determined, using dynamic coupled column liquid chromatography, for pH values varying from 3 to 11. K(a) values varied from 2.61 to 3.21 x

The hydroxylation of alpha-ionone 1 and beta-ionone 2 to their corresponding mono-hydroxylated derivatives has been examined using a recombinant E. coli whole cell system, in which cytochromes P450 SU1 and SU2, and P450 SOY were over-expressed with their cognate ferrodoxins.
