I will try to get the original paper, to see how they did it. I know from 69ron's experiments that he needed some very special technique to successfully extract 5-MeO-DMT (citric acid, sodium carbonate and DCM).

That's why I ordered some Evodia rutaecarpa and wanted to try his method on it. But now it seems that's useless. As their paper was especially about the Tryptamine content, I would suggest they used a proper technique for it...

BTW: The article mentioning the DMT (0.00026%) and 5-MeO-DMT (0.00015%) content in Evodia rutaecarpa is this one:

Maybe someone has access to it?

BTW: Something with the numbers must be wrong here. As 15 mg

from 3 kg is not 0.00015%. Probably the right number is 0.0005%.

Edit: Also from the other reports the content of the main alkaloids (Evodiamine, rutaecarpine, etc.) seem to be even lower than that indicated primarily (from the mentioned Website) just for 5-MeO-DMT. So it seems that actually the content of 5-MeO-DMT in Evodia rutaecarpa is really extremely small.

So the search continues for a proper accessible source of 5-Meo-DMT...
