New lactones in liquorice (Glycyrrhiza glabra L.)
The lactonic fraction of a commercial liquorice root extract (licorice, Glycyrrhiza glabra L., family Fabaceae), exhibiting a pleasant sweet, woody, dried fruit‐like odour, contains mainly fatty acids (C2–C16) and phenols (phenol, guaiacol), together with common saturated linear γ‐lactones (C6–C14)...

| Summary: | The lactonic fraction of a commercial liquorice root extract (licorice, Glycyrrhiza glabra L., family Fabaceae), exhibiting a pleasant sweet, woody, dried fruit‐like odour, contains mainly fatty acids (C2–C16) and phenols (phenol, guaiacol), together with common saturated linear γ‐lactones (C6–C14) and, in trace amounts, a series of new 4‐methyl‐γ‐lactones and 4‐ethyl‐γ‐lactones. Their structures have been confirmed by synthesis. Spectral data and organoleptic descriptors are given. Some 5‐methyl‐δ‐lactones, which can easily be confused with the 4‐ethyl‐γ‐lactones, are also discussed. Copyright © 2005 John Wiley & Sons, Ltd. |
