Glycyrrhiza glabra L. - Fabaceae - liquorice, sweet wood, Lakritze, Kahles Süßholz

Perennial herb, up to 1m tall; native to South and Southeast Europe, West Sibiria, West Asia, North Africa.

The sweet taste of the root is comes from the triterpene saponin glycyrrhizin, with a sweetening power 50 times greater than sugar.

„Antibacterial and antifungal activity was detected in liquorice extracts. Typical applications include cough, bronchitis and other diseases of the upper respiratory tract. In gastritis and stomach ulcers licorice root will also apply.“ http://de.wikipedia.org/wiki/Lakritze

The most abundant volatile flavor components found in extracts from liqourice root were acetol, propionic acid, 2-acetylpyrrole, 2-acetylfurane and furfuryl alcohole.

„The qualitative composition of G. glabra essential oils from different origins was relatively similar with phenols and ketones, that is, thymol and piperitone, as characteristic constituents. Aldehydes constitute the most dominant chemical group present in the 3 Glycyrrhiza species: G. glabra (17% to 30% aldehydes in volatile fraction), G. inflata (16%), and G. echinata (40% to 48%).“ Analysis shows 5-methyl-furfural (3-10%), (4E)-decenal (3-5%), cumin aldehyde (1-4%), carvone (0-3%), piperitone (7-13%), (E)-cinnamaldehyde (3-6%), thymol (5-27%), carvacrol (1-11%), p-vinyl-guaiacol (8-9%), eugenol (7-9%) and methyl eugenol (0-3%), γ-nonalactone (1-7%), β-caryophyllen and its oxide as the main components.
