Flavonoids and isoflavonoids of chemotaxonomic significance from Glycyrrhiza pallidiflora (Leguminosae)

Phenolic Constituents of Licorice (Glycyrrhiza Species)

“…A new isoflav-3-ene, pallidiftorene (2',7 -dihydroxy-4' -methoxyisoflav-3-ene), has been isolated from this species (78,315). A new isoftavone pallidiftorin (5-hydroxy-4' -methoxyisoftavone) was isolated by Lru et al (196), and a new chalcone glypallichalcone (247) has been isolated from the roots by ZHANG et al (316).…”

Flavonoids: Classification, Biosynthesis and Chemical Ecology

“…The biosynthesis is not yet clearly deined but is likely to be derived from the common C 15 intermediate of general lavonoid biosynthesis, more speciically from the reduction of dibenzoylmethanes [19][20][21] or by 2-hydroxylation of a lavanone [22,23]. These compounds are restricted to relatively few plant species and have been isolated from some species of the families Leguminosae [24], Annonaceae and Basellaceae [25][26][27][28].…”
