Evaluation of the phenolic compounds in the aerial part and roots of chicory (Cichorium intybus L.) collected from different localities of the Iran using high performance liquid chromatography (HPLC)

In this article, a phytochemical investigation including identification and measurement of some phenolic compounds in the hydroalcoholic extracts of the Cichorium intybus L. collected from 6 localities was carried out. Among the studied compounds, chicoric acid (0.55 to 6.04 mg per gram of dry plant), chlorogenic acid (0.50 to 5.37 mg per gram of dry plant), and rutin (0.56 to 2.25 mg per gram of dry plant) were found in extracts of aerial parts and chicoric acid (0.03% to 0.29 mg per gram of dry plant) and chlorogenic acid (0.84% to 2.88 mg per gram of dry plant) were found in the roots of all samples. Among the studied populations, the highest amount of major compounds (chicoric acid and chlorogenic acid) were observed in the aerial parts of the sample collected from the National Botanical Garden of Iran with 6.04 mg of chicoric acid and 5.37 mg chlorogenic acid per gram of dry plant.
