Abstract A new prenylated 3-hydroxypyranoflavanone, kanzonol Z, was isolated from cultivated licorice, Glycyrrhiza glabra , and the structure elucidated from spectral evidence. The stereochemical structure of kanzonol Y previously isolated from the licorice has been shown to be ( α R )-3,5′-diprenyl- α ,2′,4,4′-tetrahydroxydihydrochalcone by Mosher's method. In a prescreening test for bioactive compounds amongst licorice phenols using a recombinationless mutant of Bacillus subtilis M45, seven… Expand
Flavonoid constituents from Glycyrrhiza glabra hairy root cultures.
TLDR

Preliminary evaluation of antinephritis and radical scavenging activities of glabridin from Glycyrrhiza glabra.
TLDR
ESR spectroscopy demonstrated that glabridin neither produced radical, nor affected the radical intensity of sodium ascorbate, suggesting the lack of correlation between the antinephritis activity and radical scavenging activity. Expand
