- •
Cathine, CAT/norephedrine, NE/cathinone, CTN were oximated then trimethylsilylated at first.
- •
MSTFA applied in parallel with MSTFATMIS led to distinguishable new informations.
- •
MSTFATMIS provides CAT-3TMS, NE-3TMS, CTN-2TMS(TMS-oximes)1,2 partly stable products.
- •
MSTFA gives CAT-2TMS, NE-2TMS, CTN-TMS(TMS-oximes)1,2, stable, analysis ready species.
- •
Direct sample peparation in leaf tissues without extraction proved to be quantitative
