[Studies on chemical constituents in roots of Heracleum rapula].
OBJECTIVE
To study the chemical constituents in roots of Heracleum rapula.


METHODS
The constituents were isolated by column chromatography on silica gel and ODS, and identified by spectroscopic methods.


RESULTS
Nine compounds, osthol ( I ), bergapten (II), xanthotoxin (III), isopimpinellin (IV), imperatorin (V), isoimperatorin (VI), cnidilin (VII), phellopterin (VIII), rivulobirin A (IX) were isolated and identified.


CONCLUSIONS
Compounds VI, VII, VIII, IX were isolated from this plant for the first time.
