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
