To isolate and identify the chemical constituents from Polygonum paleaceum.
Chemical constituents were isolated and purified by column chromatography on silica gel,Sephadex HL-20 and macroporous resin etc. The chemical structures were identified by MS,NMR and spectral analysis.

OBJECTIVE
To study chemical composition of n-butanol fraction from Polygonoum amplexicaule var. sinense.
METHODS
TLC,normal-phase silica gel, reveres-phase silica gel, Sephadex-LH and semi-preparative HPLC were used to isolate chemical compositions of n-butanol fraction from Polygonoum amplexicaule
