HPLC of the AcOEt extracts of subterranean (roots or stolons) samples
of Glycyrrhiza uralensis showed two types of the reproducible chromato
grams distinct from those of other species (G. glabra, G. pallidiflora
, G. echinata, G. macedonica). As index compounds for HPLC of G. urale
nsis, two new compounds, named glyurallins A and B, were isolated and
their structures were defined, in addition to identification of nine c
ompounds to glycycoumarin, semilicoisoflavone B, dehydroglyasperin C,
licoisoflavanone, glycyrol, glycyrin, gancaonin N, licoricidine and 8-
gamma, gamma-dimethylallylwighteone.
