Consensus
Decision Date
KRA-01
Quantitative and Qualitative
Analysis of Mitragynine in Kratom
(
Mitragyna speciosa)
by GC-MS,
LC-MS/MS and UPLC-PDA
•
Commercially available standards
from Chromadex for 7 OH
•
Need to see recovery data
•
Include 7 OH data
•
Range of quantification must
cover whole range from SMPR
•
Precision and accuracy data is
needed across entire range of
quantification
•
Interest from ERP is in the
tandem MS method
