Abstract

A new compound named licoagrodione was isolated from the hairy root cultures of Glycyrrhiza glabra (Fabaceae) together with five known prenylated flavonoids. The structure of licoagrodione has been elucidated on the basis of spectral evidence and it was found to have antimicrobial activity indicated by disc diffusion method.
