[Study on the chemical constituents from Rumex japonicus Houtt].
OBJECTIVE
To study the chemical constituents in dried roots of Rumex japonicus Houtt.


METHODS
Isolation and purification of chemical constituents from Runmex japonicus Houtt. were conducted by solvent extraction and chromatography. Their structures were identified by spectrum analysis.


RESULTS
Two compounds were isolated from the acrtone extract of the roots and identified as emodin and rutin.


CONCLUSIONS
Compound II is obtained from this plant for the first time. The task provided evidence for the exploitation and utilization of this plant resources.
