| Mitragynine is an indole alkaloid from the plant M. speciosa. It has stimulatory, antinociceptive, and opiate-like effects, acting through noradrenergic, serotonergic, and opioid receptors.1,2 Mitragynine has a higher affinity for the µ-opioid receptor than the delta- or kappa-opioid receptors (pKi = 8.14, 7.22, and 5.96, respectively).2 Mitragynine and its derivatives have been identified in products sold as incense.3 The identification and quantification of mitragynine and related alkaloids, as well as their phase I and II metabolites, have been described.4-6 This product is intended for forensic applications. This product is qualified as a Reference Material that has been manufactured and tested to ISO/IEC 17025 and ISO 17034 international standards.
