Flavonoid glycosides of the roots of Glycyrrhiza uralensis

Phytochemistry, 1985
Abstract The structure of a flavanone glycoside from the roots of Glycyrrhiza uralensis has been confirmed as 4′-O-[β- d -apio- d -furanosyl-(1 → 2)-β- d -glucopyranosyl]liquiritigenin. In addition, two known flavonoid glucosides, ononin (a minor component) and liquiritin (a major component), were isolated from the same extract.

Identification of Tyrosinase Inhibitors fromGlycyrrhiza uralensis

Planta Medica, 2005
Tyrosinase is a key enzyme in the production of melanins. Phytochemical studies of a Glycyrrhiza uralensis extract were performed by measuring the tyrosinase and melanin synthesis inhibitory activity. Glycyrrhisoflavone and glyasperin C were identified as tyrosinase inhibitors for the first time.

Six prenylated phenols from Glycyrrhiza uralensis

Phytochemistry, 1991
Abstract A new prenylated flavone, gancaonin Q, and three new prenylated dihydrostilbenes, gancaonins R, S and T, along with two new prenylated dihydrophenanthrenes, gancaonins U and V were isolated from the aerial parts of Glycyrrhiza uralensis . The structures of gancaonins Q–V were elucidated by spectroscopic methods.

Galactomannan from the seeds of Ural licorice (Glycyrrhiza uralensis Fisch.)

Applied Biochemistry and Microbiology, 2010
Galactomannans from the seeds of Ural licorice (Glycyrrhiza uralensis Fisch.) obtained by hot water extraction of freshly ripened (GGu-1) and overwintered (GGu-2) seeds were studied. GGu-1 and GGu-2 (yield, 1.98 and 1.99% of the seed weight) had molecular weights of 1379 and 877 kDa, respectively; their solutions were characterized by high viscosity ...
