title: Isolation and purification of flavonoid and isoflavonoid compounds from the pericarp of Sophora japonica L. by adsorption chromatography on 12% cross-linked agarose gel media.
abstract: A method for isolation and purification of flavonoid and isoflavonoid compounds in extracts of the pericarp of Sophora japonica L. was established by adsorption chromatography on the 12% cross-linked agarose gel Superose 12. The crude extracts were pre-separated to two parts, sample A and sample B, on a D-101 macroporous resin column by elution with 20% ethanol and 40% ethanol, respectively. Samples A and B were then separated by adsorption chromatography on Superose 12 with 40% methanol as the mobile phase. Eight compounds including four kinds of flavonoids and four kinds of isoflavonoids were obtained by the proposed method. The adsorption mechanisms of flavonoids and isoflavonoids on Superose 12 were also discussed.
