The AOAC Expert Review Panel (ERP) approved a method for the quantitation of alkaloids in Mitragyna speciosa for consideration as First Action Official MethodSM status. The previously published method summarized a single-laboratory validation of two alkaloids, mitragynine and 7-hydroxymitragynine, in raw materials and finished products. The methods performance was compared with the AOAC Standard Method Performance Requirement 2015.008. With repeatability precision (RSDr) ranging from 0.51 to 0.95% and recoveries from 93.6 to 98.9% in the different product matrices, the ERP adopted the method and provided recommendations for achieving Final Action status.
