Kratom alkaloids mixture is a mixture of analytical reference standards containing alkaloids found in M. speciosa (Kratom in Thai).1 The mixture contains the opioids mitragynine and 7-hydroxy mitragynine, as well as mitraphylline, speciogynine, and speciociliatine, which are structurally similar to known opioids. The mixture is supplied in an amber ampule in which the headspace has been purged with argon. It is designed for use in methods development and as a reference standard for these substances during routine analytical checks using HPLC or LC-MS instrumentation. This product is intended for research and forensic applications.
