  • Objective: To observe the antinoeiceptive effect of total Ervatamia yunnansis alkaloid(TEYA) in mice. Methods: The mice hot-plate antinociceptve test was used to study the analgesic effects of TEYA and the effect on morphine in mice. Results: The three groups with different dosage of TEYA could significantly increase the pain threshold in mice and the effects increased in a dose-related manner. TEYA(10、20 mg/kg) combined with morphine 4 mg/kg had a synergic analgesic effect. The analgesic effect of TEYA could he partly blocked by naloxone 4 mg/kg. There were significantly differences between administration group and control group in the hot-plate test. Conclusion: TEYA has significant antinoeiceptive activity in hot-plate lest in mice which may be mediated by way of opioid receptors.
