The aim of this study was to evaluate the analgesic effect of alcoholic extract of the core is made of cherry in male rat. Methods: In this study, 36 male rats were divided into 6 groups of 6: control (normal saline 1mg/kg), morphine (1mg/kg), cherry kernel extract (100, 150, 250 mg/kg, I.P) and the group treated with Naloxone (1mg/kg), in combination with low doses of cranberry seed extract (150 mg/kg) were divided. Then, to assess the anti-nociceptive effects of the extract, we used Writhing and Tail-flick tests. Results: The results of the study showed that the extract significantly inhibited the number of contractions induced by acetic acid. The results of Tail-flick test showed that the delay time of tail removal after injection in all groups was significantly associated with latency of tail withdrawal before injection (P <0.05). The extract group with a dose of 250 (mg / kg body weight) showed more analgesic effects than other doses of the extract and the mean delay in this group was significantly higher than other doses (P <0.05). Conclusion: According to the present results, the Sour Cherry Extract kernel have analgesic effects. The presence of flavonoids might be responsible for the anti-nociceptive activity of this plant.
