The constituents were isolated and purified by silica gel, Sephadex LH-20 and MCI gel chromatography and recrystallization. The structures were elucida- ted on the basis of the chemical evidence
Stilbenoids are the main components of leaves and stems of Pholidota chinensis. In the present investigation, high-speed counter-current chromatography was used for the separation and purification of two classes of stilbenoids, namely, bibenzyls and 9,10-dihydrophenanthrenes, on a preparative scale
