Abstract:
The chemical composition and antinociceptive potential of a lyophilized decoction of the oregano flowers (Origanum vulgare L.) and the aerial parts of chicory (Cichorium intybus L.) in the flowering phase (LCOD-lyophilized decoction of the oregano and chicory) was investigated by HPLC-DAD and the acetic-acid-induced writhing method. HPLC-DAD analysis of the LCOD revealed the presence of 20 phenolic compounds, where the dominant phenolic components were ferulic acid (205.19 mg/g LCOD), rosmarinic acid (81.55 mg/g) and hyperoside (79.42 mg/g). The results of the antinociceptive activity showed a strong analgesic effect of the LCOD (15 and 30 mg/kg), which significantly (p < 0.001) reduced the number of writhings (98.40 and 99.23%, respectively) induced by acetic acid. These encouraging results indicate the analgesic potential of LCOD and suggest validation through clinical trials.
