Evaluation of mitragyna speciosa analgesic activity in mice / Salina Mohd Saad
The leaves of mitragyna spectosa (Rubiaceae) have been traditionally used as substitute for opium. Mitragynine is a major alkaloid constituent that is known to produce opioid like action when smoked, chewed or drunk. This study is done to evaluate analgesic properties of mitragyna speciosa in mice....

The leaves of mitragyna spectosa (Rubiaceae) have been traditionally used as substitute for opium. Mitragynine is a major alkaloid constituent that is known to produce opioid like action when smoked, chewed or drunk. This study is done to evaluate analgesic properties of mitragyna speciosa in mice. Investigation of the antinociceptive activity of intraperitoneal (i.p) injection of saline, Mitragyna speciosa extract (l5mg/kg, 25mg/kg and 35mg/kg) and acetaminophen (35mg/kg) was done by using hot-plate test.
