Q: Would this extraction work for reed canary grass (Phalaris arundinacea), assuming you wanted 5-MeO-DMT?
A: It certainly would! If you plan on doing it, remember that there's only 0.02% DMT in Phalaris, so you’re going to need a hell of a lot. Also, it would be best to do around 3 defats after the acid water.Break 1 pound of Mimosa Hostilis rootbark into 1" pieces using new heavy-duty wire cutters, then grind it all up in a glass-topped blender, a little at a time. Grind the rootbark up to 1mm in diameter or smaller. Finer is better.
Polar Extraction: Premix in an empty 1 gallon plastic jug: 1 quart white vinegar & 3 quarts water. Put the ground up Mimosa in a 3 liter crockpot, then fill it with the water/vinegar solution. Stir well and turn it on "high." After 2 hours, remove the crockpot ceramic liner, hold the lid on slightly offset, and pour off most of the liquid into a 1 gallon wide-mouthed glass or stainless container. Add the remaining water/vinegar solution to the crockpot again. Stir well and turn it on "high." After 2 hours, remove the crockpot ceramic liner, hold the lid on slightly offset, and pour off all of the liquid into the same container again. Discard the rootbark fiber and save the two combined extractions in the 1 gallon container. Allow the vegetable particles in the extraction in the 1 gallon container to settle to the bottom overnight. Then pour off the liquid into an empty 1 gallon glass wine jug, being careful not to pour off any of the vegetable sludge at the bottom. Discard the sludge and keep the contents of the wine jug. Use three water-vinegar extractions rather than two. Divide up the water-vinegar mix so that you roughly use 50% for the first extraction, 25% for the second, and 25% for the third extraction. After the last extraction press out the fiber to squeeze the last bit of liquid from it.
Basification: Premix a solution of: 5 heaping tablespoons (70grams) of lye (Lowes Hardware, item # 146450, "Roebic Crystal Drain Opener") very slowly added to 1 pint of warm water, and stir well. Slowly add this solution to the wine jug, then cap the jug. Gently tilt the wine jug back and forth for 1 full minute to mix. Basify to a ph of 13. If you don't have ph papers, basify till it turns black, then add an additional 25% of whatever amount of basification solution you used. This is to guarantee that you're at a ph of 13. The brown foam you see floating on top of the basified extract after tilting the jug should flatten out to a thickness of no more than 1/2" after 45 minutes or so if you've used enough lye. Add a bit more lye and re-tilt if it's thicker than that.
Non-polar Extraction: Add 275ml of (Ace Hardware) VM&P Naptha to the wine jug. Add exactly enough warm water to the jug to raise the liquid level to an inch below the top. Cap the jug. Gently tilt the wine jug slowly back and forth for 5 full minutes to mix the contents. Allow the jug to sit undisturbed on a table for at least 3 hours. There should now be two layers visible in the jug, a lower dark one and a smaller clear one on top filling the neck of the jug. Use a glass turkey baster to suck up the top clear layer into a large glass baking pan. Be very careful not to suck up any of the lower brown foam/black liquid layer.
Freeze-Precipitation: Cover the glass baking pan with plastic wrap and place it in a freezer for 3 days to precipitate the DMT crystals. Remove the pan from the freezer and quickly lift the plastic wrap from a corner of the pan. Tilt the pan and slowly pour off all of the naptha through the exposed corner, being careful not to dislodge the crystals stuck to the bottom of the pan. Re-seal the corner of the pan by stretching the plastic wrap back over it. Allow several hours for the pan to reach room temperature, then remove all of the plastic wrap. Allow the crystals in the pan to completely dry out overnight in a cool place. Then use a pair of single-edged razor blades to scrape up the impure DMT crystals. The freeze-precipitation technique is a double-edged sword. Very convenient and high quality, but highly dependent upon knowing the approximate amount of DMT expected to be precipitated. If you use too much naptha, then only a little bit precipitates out. If you use too little, then it doesn't extract it all out of solution. It is the simplest case of re-crystallization. The best way using it if you aren't very sure of the yield is to use a slight excess to extract, then evaporate it down to 10% of the original volume. THEN freeze it. This will pretty much guarantee excellent results. For example: For a pound of rootbark use 500 milliliters of naptha to extract. Then evaporate it down to 50 milliliters. Then freeze it and filter out the crystals. By the way, you must very quickly filter it within a minute or two after removal from the freezer so it doesn't have any time to warm up. And your freezer can't be marginally cold. If it doesn't freeze ice cream HARD, then it isn't cold enough. -20C is about where it should be.
