SWIM will be extracting 500g of MHRB in about a week's time, and intends to use the following original tek, with any helpful modifications the Nexus community might have. The quantities which SWIM is especially unsure about are marked with (?). Any advice would be greatly appreciated.

1. Place 500g powdered MHRB in a large, stainless steel pot
2. Add enough water to make a thick slurry
3. Add ~30% HCl dropwise while monitoring pH to acidify the slurry to pH 3(?)
4. Simmer for 1 hour(?) and allow the mixture to cool
5. Reconstitute with water if significant loss occurred during heating
6. Add 1g(?) magnesium shavings
7. Let this mixture sit for 3 days, stirring at least 2 times each day
8. Add sodium carbonate while monitoring pH to basify the mixture to pH 11
9. Add the bare minimum amount of water needed to homogenize the mixture
10. Let mixture sit for 3 days, stirring at least 2 times each day
11. Add anhydrous magnesium sulfate until there is no indication of moisture
12. Transfer the powder to a stoppable glass decanter
13. Cover in acetone (made anhydrous by excess anhydrous magnesium sulfate)
14. Let slurry sit for 24 hours(?), agitating 3 separate times for 3 minutes
15. Decant and reserve acetone
16. Repeat steps 13-15 2(?) additional times
17. Combine and evaporate the acetone
18. Redissolve extract in minimal acetone and salt out with FASA
19. Filter and wash with methyl ethyl ketone

What's the magnesium shavings for?

I see this working, but requiring lots of solvent because you have soo much water saturated magnesium salts, as well as bark, and sodium carbonate. I think it takes 1g of dry mgso4 to absorb 1ml of water, so the less water, the less mgso4 and less volume of powder you have to pull from in the end. I would recommend adding a filtering step, then reducing the liquid down to a goo. Not quite dry, but still runny. Then i would add enough sod carb, or even better lime to make it almost dry. Add a little more water to make it pastey, let it sit and react stirring often for a few hrs then dry with mgso4. The less you end up with to pull from, the more efficient, and easier the extraction will become. Also, powdering as fine as possible with a mortar/pestle before pulling with acetone will greatly increase the efficiency of the extraction ime.

I have tried this with mhrb goo with spectacular results, and with the added benefit of requiring no NP, or having to purchase expensive dlimo. I've also tried it with dlimo on cactus resin. I think dlimo would be a good addition to get an additional degree of purity if you fasa'd the alkaloids out, then redissolved and basified again out of koh/lye water.

You would be left with mostly fb dmt and a small % of noxide. To recover the rest of the oxides just pull from the basified water with dlimo and salt with fasw. Oxides tend to stay in solution when fb is precipitated out of water ime.

Great advice, thanks. The magnesium is in there to reduce the dmt oxide. Would the acetone still decant easily if SWIM used lime instead of soda ash? SWIM has heard that it makes for a messier process. I'll probably omit the reconstitution step in order to avoid the need for more epsom salts.

ime, it all depends on how fine you powder it. If you go full on talc, it could take days to properly clear, but it will decant out if left alone. Whereas chunks, will fall out much sooner. Lime/soda ash work just fine decanting out of tone, it just depends on the grind.

Thanks. SWIM greatly appreciates it.

can you explain the theory behind the tek? What do magnesium shavings do?

Why let it sit for 3 days after basifying?
What does anhydrous magnesium sulfate do?

I still dont understand why do people go thru all this, when you can just mix mhrb with NaOH and then pull with solvent and get your crystals the same day?

I mean the most imporant thing is getting the crystals and once you have them theres a few diffrent things you can do to purify if you wanted? right?

The magnesium is there to prevent the oxidation of DMT, and hopefully reduce some of the existing oxide. The 3 days isn't super important, but theres no hurry and SWIM would like to ensure that the reaction proceeds fully to equilibrium. Anhydrous magnesium sulfate is a dessicant to absorb any extra water; SWIM would rather not have random water-solubles in his acetone extract.
