This study was done to compare the analgesic properties of cucumis melo (CM) seeds oil extract against ibuprofen on rattus norvegicus albinus (Wistar Albino rats) using hot-plate test. Oil extraction was made by utilizing a soxhlet apparatus maintained under 60-70 C for five hours using 80% methanol. Randomization of the three groups was done via drawlots procedure and drugs were administered via syringe feeding. The analgesic properties of CM and ibuprofen were evaluated via Hot-plate test. Onset of pain and the pain tolerance were noted by observing the rats' paw-licking and jumping out of the beaker, respectively. CM group showed the longest time before pain onset, with a mean reaction time of 16.74 seconds. As for pain tolerance, the Ibuprofen group held the longest time with a mean reaction time of 8.69 seconds. Pain threshold (H-1.87, P=.039) and pain tolerance (H=3.29, P=0.193) results showed that there was no statistically significant difference among the analgesic effect of CM and Ibuprofen.
