So I finally organized that paper.
I have no idea if it would be OK to post the pdf here, anybody knows?
(Probably not, due to copyright I think...)
But IMHO it is actually a pretty bad work, rather hilarious, if not ridiculous.
The idea behind the paper's work:
The evodia rutaecarpa as a medicine has shown some "unpleasant" effects if taken in higher dosages. As the main medicinal alkaloids (evodiamine, rutaecarpine, etc) do not affect 5HT1A, but the total alkaloids show some 5HT1A effect, it was suggested previously that probably the contained tryptamines are responsible for this activation and that probably they are then responsible for the unpleasant effects.
So in this work they showed in the first half of the paper that the contained tryptamines (DMT and 5-MeO-DMT) do bind to the 5HT1A receptors and in the second half that they are present in the plant.
My comments:
It was already well known that DMT and 5-MeO-DMT bind to 5HT1A so half of the work was IMHO completely useless.
With the amounts of these tryptamines in the plant the "unpleasant" effects cannot come from these compounds, that's completely impossible (not even talking about the fact that these compounds are not orally active!). And the needed dosages for even threshold effects are well known. Did they actually even make the slightest research about the properties of DMT and 5-MeO-DMT???
They also knew, that the total alkaloid effects of E. rutaecarpa doesn't have any 5HT2 effects.
If the tryptamines would be in there for any reasonable amount there would certainly be a 5HT2 effect!!! (especially from DMT)
That's at least my conclusion. Maybe I'm wrong...Or were all these things not yet known in 1997?
But back on topic about the measured amounts of DMT and 5-Meo-DMT. As I already suggested, there's an error in Trout's notes: It's 0.0005% not 0.00015% for 5-MeO-DMT.
(maybe somebody could correct this value on the Nexus wiki page:
https://wiki.dmt-nexus.me/5-MeO-DMT)
This is how they extracted the tryptamines from 3kg of the ground dried fruits:
1) Extracted 3 times with 3L ethanol
2) The extract was filtered and concentrated to give 224g.
3) The extract was split up into a water soluble part (81g) and the rest (143g)
4) The water soluble part was basified with concentrated ammonia (no PH indicated) and extracted with chloroform (3x200mL), which yielded 250mg
5) Si gel column chromatography with hexane, hexane-chloroform, chloroform and chloroform-methanol, which gave 19 fractions.
6) fraction 8 (33.8mg) was then run through a Si gel column and HPTLC, which yielded 15mg 5-MeO-DMT and 7.8mg DMT.
The reason why they just processed the water soluble part was, because only this part showed 5HT1A activity in their tests.
Final comment by me:
As the total extract didn't show any 5HT2 activity I am pretty convinced that Evodia rutaecarpa really only has trace amounts of (5-MeO-)DMT and that the problem wasn't an extraction error...
Also it would IMHO additionally be a poor source as there are mainly other (indole-)alkaloids in there and separating them by easy means is basically impossible...
So IMHO this plant has definitely died as a possible source...unfortunately...
Any comments???
I claim not that this is the truth. As this is just what got manifested into my mind at the current position in time on this physical plane. So please feel not offended by anything I say.
