[Chemical constituents in herbs of Polygonum jucundum].
OBJECTIVE
To investigate the chemical constituents in herbs of Polygonum jucundum.


METHODS
The 85% ethanol extract was separated by means of silica gel and Sephadex LH-20 column chromatography. The compounds isolated from the plant were identified by physicochemical properties and spectroscopic evidence.


RESULTS
Eight compounds were isolated and identified as: quercetin-3'-O-beta-D-galactoside (1), 8-methoxyquercetin (2), pigenin (3), luteolin (4), quercetin (5), 3,5,7-trihydroxychromone (6), p-hydroxybenzaldehyde (7), beta-sitosterol (8).


CONCLUSIONS
All compounds were isolated from this plant for the first time, compounds 5- 8 were isolated from the genus Polygonum for the first time.
