This study investigated anti-inflammatory activity of C. sordidum acetone extract in egg albumen-induced paw oedema and formalin paw lick test in rats, while analgesic activity was determined by acetic acid-induced abdominal writhing test in mouse. Bioactivity guided analgesic effect were also carried out on solvent-solvent partitioned and chromatographic fractions. Rats administered with extract progressively showed significant reduction in oedema formation 60 minutes post-induction. Dose-dependent inhibition of formalin-induced paw lick was observed at early and late phases of the experiment compared to indomethacin. Abdominal writhing was significantly inhibited with 400mg/kg extract effect (73.1%) comparable to aspirin (75.9%). Most active chromatographic fraction identified as F7 (79.5%) showed significant analgesic activity, higher than aspirin (55.0%). Results established anti-inflammatory and analgesic of C. sordidum. Further studies are on-going to identify and characterize the bioactive principle responsible for these pharmacological effects.
