Studies on chemical constituents in roots of Codonopsis convolvulacea Kurz

OBJECTIVE:To Study the chemical constituents in the roots of Codonopsis convolvulacea. METHODS:Chromatography and spectral analysis were used to isolation the constituents and elucidate their structures.RESULTS:Five compounds were isolated from the alcohol extracts of the roots and identified as taraxerone(1), taraxerol(2), shikimic acid(3), syringaresinol (4),stigmasterol(5).CONCLUSION:All the compounds are isolated from the roots of this plant for the first time.
