I've been reading up on the manske tek lately and it got me thinking why cant dmt be done like this except with freebase. So here's an idea:

Boil the plant material with a dash of vinegar and strain the tea several times until the solution is relatively clear and down to a small volume. (or maybe no vinegar)

Add salt until no more will dissolve.

Prepare a saturated sodium carb solution and add to the mix at an equal ratio of the tea.

Put in the fridge and there should be a precipitation correct? Since dmt freebase is almost insoluble in water?

I'm curious to know if anyone has tried this or something similar or in theory if it will work. I'm willing to test this if you guys think it may have a possibility of success. What do ya think?

I'm wanting to find a way to extract without using any solvents whatsoever. This would be amazing and safe.

Doesn't work. The reason it works with harmalas has to do with some complex ion exchange thing of chemistry, but it doesn't work with DMT.

Really? have you tried this?

I've read that dmt will precipitate out of a lye solution, and since dmt has a pka of 8> sodium carb should be strong enough to facilitate a precipitation especially with a strong NaCl solution which I've read helps push dmt into solvents. 69 Ron says he bases with sodium carb but uses a better solvent than naphtha. I think I'm going to try this as an experiment to see what happens, if it doesn't work I'll just base with lye and pull with solvent. I have a strong feeling this may work, I haven't found anyone that has tried this using salt, this may be the key?

lots of things may precipitate out of a saturated salt/lye solution, what makes you think it's selective to DMT?
and how do you plan to separate the dmt from the salty mess?

pka means half the species in solution are salts, and half are free base; you'll lose half your yield at that pH
if you just isolate your free base. this is why people favor lye over sodium carb.

people use salt to break up emulsions, but there's no yield advantage just adding it to a basic solution

Freebase dmt is insoluble in water unlike the other alkaloids in the plant material. And I would just make sure there is no sediment that settles when adding salt and sodium carbonate by filtering through a coffee filter. Then after (if) the dmt precipitates I will filter again through a coffee filter and collect it. And give a warm water wash.



Thanks for telling me this, I thought it was just the point where all is freebased. I'm not very worried about losing yeild as this being a non toxic extraction would feel successful to me, I reckOn I could get the ph up to 10+ . Wouldn't the salt be beneficial for precipitation though due to the ionic bond or whatever that occurs as in the manske tek, i read on this forum it does something else and also helps the emulsions as you say..Thanks for the replies.

as was mentioned, the manske tek wouldn't be advantageous when extracting dmt.
you'd be complicating things for no practical reason. dmt has only one pKa , 9.55 or so,
there's not any reason to salt it (unless you're adding acid to the nonpolar to convert the free base to a salt)...99.96% is free base at pH 13.6. even at a pH of 10, >30% will be in the aqueous phase..
how would you separate DMT from all the other salts?
also, any other alks with similar pkas and polarity will not be separated using the procedure
you listed.

but, if you just feel like experimenting, have at it

Erowid states that the pka is 8.68 which at a +2 would be 99% freebase. Or has this been proven to be wrong? As I understand it, dmt solubility in naphtha is why nobody uses sodium carb, as I've read 69 Ron had gotten better yields pulling with chloroform/dcm & basing with NaCa, or about the same as using lye & naphtha.

I'm not trying to be arrogant if thats the vibe your getting. I know your way more knowledgable than I.

I'm going for it! There's not much to lose. I just wanted to get some opinions first from you guys.

pls report your results.
I also use dcm, but lye to basify. I posted a pka chart somewhere on the forum.

Might it be prudent to find out first what is IN MHRB tea?

Let's see...

* Tannins (bleeuurrgh)
* Active alkaloids
* Other alkaloids (?)
* Plant fat
* Plant mass, proteins, etc


It would be 'trivial' to isolate any individual component. All you need is a method that yanks out everything else. For instance a person could yank out the tannins from the tea with some egg whites, from what I hear. That's one component gone. Then continual filtration should remove most of the plant matter, leaving the rest. From then on, what next?


Couldn't a person just pump it through a variety of solvents to come out with some crude isolate?

A/B separates all but two of the components you listed (alks and perhaps a bit of some tannins). re-x isolates the alks.
trivial or not, most people I've seen like simplicity in their extraction, without sacrificing yield. only a few like to really experiment.

running a solute through a variety of solvents won't give a crude extract, but a more refined product. it's called solvent partitioning.
