http://troutsnotes.com/w...14/11/SoS_2004_Trout.pdf It seems there is a big variability in alkaloid content, some contain DMT, NMT, 5-MeO-DMT, unknown alkaloids, a mix of those or nothing at all. Please proceed with caution.
I highly recommend you to get a TLC kit or at least some ehrlich reagent to know if there at least are tryptamines in your extract.
The extracts that turned out positive for alkaloids were made with dried plant material, not sure if that will influence but might as well do it similarly.
You could try straight to base, yes, and then see what results you have from it. You can always further purify it later if you want.
I would definitely not combine with MAOIs until you are 100% sure you have only the alkaloids you want and nothing else mixed in. I'd start with STB a smallish amount of dried material, see what I have, use TLC/ehrlich, if results are positive, maybe smoke a small amount, but I'd only really consume orally with a MAOI if I was sure I only had what I wanted, if TLC only showed spots for the wanted alkaloids and nothing else, and the smoking test was fine (or pay a bit and
send to EC for testing)
Good luck and let us know how it goes if you try!
