[Studies on chemical constituents of root of Cichorium intybus].
OBJECTIVE
To study the chemical constituents in the root of Cichorium intybus.


METHODS
The compounds were isolated and identified by column chromatography and NMR, IR, MS data.


RESULTS
Twelve compounds were isolated and identified.


CONCLUSIONS
2,3,4,9-tetrahydro-1H-pyrido-(3,4-b)indole-3-carboxylic acid was isolated from the Cichorium genus for the first time, azelaic acid and daucosterol were isolated from the the plant for the first time.
