Lab analysis of mimosa extract ?

[Shaolin]

Were there any lab analysis (GC/MS etc) done on the mimosa extract (not just on "jungle spice" and besides the one from the DEA) ?

Yes.

If you analyze white spice extracted its only one main compound. Unless the oxide is present GC/MS won't be able to tell.

Yeah read about, thanks.

I am particulary interested in an A/B and/or STB analysis, since I'm still confused whether the technique changes the composition of the extract.

Yes.

LC-MS FTW.


would be awesome if MALDI could be implemented, but the analytes would probably be too close to the matrix masses

True. But what advantage would MALDI add besides high mass resolution?

Its the same if one recrystallizes the material and ends up with a fluffy white product that makes one see funny things.

Of course it will vary if one uses a different solvent like hexane as opposed to toluene as initial non polar solvent when extracting base.

simplicity of application, particularly sample prep.
add half a microliter matrix, half a microliter analyte to the plate target.
dry, load the plate, and zap. done.

^^True. I remember with MALDI I could just slap some cells on a plate and analyze some peptides. Was nice for those molecules.
