- Title
New lactones in liquorice ( Glycyrrhiza glabra L.).
- Authors
Näf, Regula; Jaquier, Alain
- Abstract
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.
