Isolation and GC-MS determination of flavonoids from Glycyrrhiza glabra root

Components of the ethylacetate extract of Glycyrrhiza glabra root were separated based on their acid-base properties. The major components of the fraction soluble in aqueous NaOH were identified by GC-MS as glabridin, the principal component of the ethylacetate extract of licorice root (Glycyrrhiza glabra L.), 4-O-methylglabridin, and hispaglabridin B. The isoflavene glabrin was identified in addition to the isoflavan derivatives. __________ Translated from Khimiya Prirodnykh Soedinenii, No. 3, pp. 236–240, May–June, 2006.
