title: Flavonoids from preparation of traditional Chinese medicines named Sini-Tang.
abstract: A new flavonoid, 7-hydroxyl-4'-O-beta--(6'-O-alpha-hydroxylpropionyl)-glucopyranosyl dihydroflavone (1), together with 12 known flavonoids, has been isolated from the EtOAc fraction of the aqueous extract of Sini Tang. The structures of the compounds have been elucidated by spectral methods. The new compound comes from Glycyrriza uralensis Fisch., as determined by HPLC-ESI-MS.
