Active Phytochemicals
1. Glycyrrhizin
Glycyrrhizin, a triterpenoid compound, accounts for the sweet taste of licorice root. This compound represents a mixture of potassium-calcium-magnesium salts of glycyrrhizic acid that varies within a 2–25 % range. Among the natural saponin, glycyrrhizic acid is a molecule composed of a hydrophilic part, two molecules of glucuronic acid, and a hydrophobic fragment, glycyrrhetic acid. The yellow color of licorice is due to the flavonoid content of the plant, which includes liquiritin, isoliquiritin (a chalcone) and other compounds. The isoflavones, glabridin and hispaglabridins A and B have significant antioxidant activity, and both glabridin and glabrene possess estrogen-like activity

  • Glycyrrhetic acid
  • Glabridin
  • Liquiritin
  • Isoliquiritigenin
  • Isoflavones

Along with triterpene, saponin, flavonoids, polysaccharides, pectins, simple sugars, amino acids, mineral salts, asparagines, bitters, essential oil, fat, female hormone estrogen, gums, mucilage (rhizome), protein, resins, starches, sterols, volatile oils, tannins, glycosides and various other substances.
