3 microliters of a 5mg/mL solution of the red stuff again gave only dmt in GC-MS. I think this is the only major alkaloid in this mixture. I think the colors are a result of tannins. M. hostillis bark is loaded with tannins so its very likely they are causing the red pigment in "jungle spice". Furthermore tannins may be altering the effect of DMT by non specifically binding to various proteins in the brain or lung or maybe elsewhere. I do not know if the tannins found in this bark could cross the blood brain barrier or how easily they would enter the blood either. one good thing about certain tannins is that they dont get too much into the blood because their toxic. The GC temperatures might not be high enough to volatilize these compounds so thats probaly why they are not in the mixture. Using higher temperatures is not desired because my friend actually uses this machine for work and doesnt want to fuck up his column.

By FID i just ment flame ionization detector. Its just a detector thats more for quantitative analysis. He could inject the red stuff into this machine again to see if the impurities are still present. However it gives no identification information like MS spectra.

LC-MS is too much of a pain to set up and might attract unwanted attention to my friend. Column chromatography is also no small task and could take lots of time to identify compounds that are already known to be in the plant. TLC however could easily show if phenolic compounds are present in the mixture by spraying with fast blue B or some other similar spray reagent. Also dragondorfs reagent could easily be showed to identify DMT and other alkaloids if they are present and seperate.

I am not a member of that nook web board. I know all the GC-MS specifics but am unsure why they would need that information. Its fairly basic to identify low molecular weight tryptamines in GC.
