Abstract A new prenylated dibenzoylmethane, kanzonol A, and a new chalcone, kanzonol B, along with two new isoprenoid-substituted flavones, kanzonols D and E were isolated from the roots of Glycyrrhiza eurycarpa. Their structures were elucidated by spectroscopic methods. The diprenylated chalcone, kanzonol C, was also isolated from this species for the first time as a natural product.

Isoprenylated flavonoids from hairy root cultures of Glycyrrhiza glabra
TLDR
Two new prenylated flavonoid compounds were isolated from the hairy root cultures of Glycyrrhiza glabra along with eight known flavonoids and the structures were elucidated as 3-prenyl-2′,4,4′-trihydroxychalcone and (6a R, 11a R )-4-p Renyl-3-hydroxy-9-methoxypterocarpan, respectively. Expand
