6. Based on the supporting information, what are cons/weaknesses of the method?
Cons/weaknesses: detection method, only mitragynine is quantified
7. Any general comments about the method?
The proposed method is simple but may be critical on the fact of the detection at 226 nm
which could, may be also detect other compounds than the target one. The other drawback of
the proposed method is that it allows the quantification of only mitragynine.
