Abstract
Objective:
To investigate the chemical constituents of Cichorium intybus.
Method:

Result:
Seven compounds were isolated from the roots of C. intybus and four of them were identified as alpha-amyrin, taraxerone, baurenyl acetate and beta-sitosterol.
Conclusion:
All the four compounds were obtained from the plant for the first time.
