[Studies on chemical constituents in herb of Polygonum orientale].
OBJECTIVE
To study the chemical constituents of the essential substance from Polygonum oriental.


METHODS
Compounds were isolated with silica gel and polyamide chromatography and their structures were determined by spectral analysis and chemical evidence.


RESULTS
Six compounds were obtained and identified as myricitrin, luteolin, gallic acid, catechin, protocatechuic acid, p-hydroxycinnamic acid.


CONCLUSIONS
Six compounds were isolated from P. oriental for the first time.
