Had a few fleeting thoughts this morning, that are probably best shared rather then tucked away. For an extraction that requires no defating for plants such as grasses/leaves/etc where the compounds to be isolated are alkaloids.
Reverse Acetone Crash:
Reflux 3x30 minutes in dry acetone with powdered and dry plant material. Alternatively let soak for 12 hours with agitation, 3x. Evaporate or distill off some of the excess acetone(depending on how much solvent was used). Dry the acetone with Calcium Chloride or MgSO4(shouldn't take much), filter(sugars and other junk may crash after water removal) and let stand for a few hours. Add xylene/toluene/limonene any other miscable non-polar solvent, until the binary solvent system favors non-polar I.M. interactions and clouds form(if they are visible). Allow to crash over night. This won't be as pretty as fumarates but there should be an oily mass formed on the bottom of the container. A characteristic of finicky tryptamines.
The solvent is then decanted. And one could very easily add water, a strong base or perhaps a weak one with a high pKa, and a nonpolar solvent of their choice to pull again, cleanly.
The acetone could easily be partitioned off with repeated washings with water and a separatory funnel and discarded or distilled. The non-polar used probably could be cleaned if necessary with activated carbon or distillation.
Caveat:
This of course all depends entirely on if the DMT and or 5-MEO-DMT salt is soluble in acetone. I assume with faulty logic that it would be. It may be a solvent heavy idea but defat's are solvent heavy as well, and acetone evaporates readily without expelling heat energy."Green defat" extract:
Go about your business doing an A/B as per usual. After the boils are combined and the solution reduced on the stove, and after it's been let to rest in the fridge and filtered. Do you're defat's; however after you pull your first solvent soak from the jar/jug/whatever, add fresh solvent. To your dirty solvent add a lion-pinch of activated carbon and let both your defat, and the activated carbon sit over night. Filter the activated carbon away and discard. Repeat defat using the newly freshened solvent.
Go about your way to the basic phase.
Caveat:
The only problem with this is, how well can Activated Carbon clean up a chlorophyll ridden solvent? Only one way to find out I would suppose
...(experiment).
If anyone else has any ideas here is probably a good place to work from
. Remember MHRB is on it's way out the door, alternative plant sources will be a way of life. These are things to keep in mind.
