OBJECTIVE To study the tonic constituents in Fructus Corni, the pulp of Cornus of ficinalis. METHOD Hot-water extraction, ethanol precipitation and column chromatography on DEAE-cellulose and Sephadex G-200 were used to isolate and purify the polysaccharides in Fructus Corni. HPGPC was used to determine the purity and measure the mean molecular weight of… (More)
