This is a variation of a procedure used to extract calcium bufotenate from yopo and cebil.
It has worked well using MHRB and chaliponga and shows promise (with a few added steps) on cactus.
The extract is dark and nowhere near the clear glass shards that many are fond of, but smokes very well and the experience is a much more well rounded complete plant experience than purer extracts. It is the closest that freebase extract has ever come to ayahuasca for me.
The extract could very likely be refined into pure crystal by a further extraction with a selective NP solvent, an NP wash, and recrystalization.
MHRB will yield a somewhat dry powder, fattier plants like chaliponga will yield more of a tar. A pre defat may be possible. Also, though the tek calls for acetone, MEK or various alcohols would probably work to various degrees. Here's to hoping that there are others out there willing to help me find out.

The procedure:
Grind the plant material fine
Mix an equal weight of calcium hydroxide with the powdered plant material
(sodium carbonate, a small amount of lye, or enough ammonia to make a wet paste would probably also work - again, I invite you to help me find out)
Add enough water to make a wet paste of the mixture
Spread the mixture out on a plate or whatever and let it dry completely, stirring and chopping it every so often
Crush the mixture fine with a mortar and pestle
Add enough acetone to make a very wet slush and shake the shit out of it
Filter through a buchner funnel with 102 filter paper or a coffee filter
Repeat the acetone process on the powder material twice more
Combine the acetone extracts and evaporate
Scrape and enjoy

That is sweet man. Is the Noman tek posted in this same section yours??? Good to have you hear man, love people doing shit like this. Hope you stick around and help out, all the knowledge we can get is always good.

Yeah, that's me. Thanks for the kind words. Looks like you've come up with a nice procedure or two yourself.

Going over my notes, I was reminded that I did indeed clean up the chaliponga extract, but instead of how I described it above, I redissolved the tar in acetone, added that to acidulated water and evaporated the acetone off under a fan. I rebasified that and extracted with naptha, resulting in a crumbly brown powder that was much easier to deal with than the tar, but still full spectrum.

That's sweet!!! What were your yields??? Any particular reason for not using the vacuum pump when you evaporated the acetone??? I know some occasions arise where that may be difficult. Overall nice man. Love the work of both. The acetone really rips shit up though, like you were saying other things might work just as well if not better. A methanol wash followed by an ethanol wash might pull something. Personally would skip out on the ammonia, in the search of something better, and go with something else in the second step. It is certainly user friendly which is awesome. Love user friendly shit, just hate that other places (yield and purity) usually have to suffer for it. Not really worth the time or materials to try and clean the final product up as it is good enough to serve the purpose. Hell yea man, hope to hear and see more. Guess I have to think about it a little more. LOL

For some reason I only recorded the yield of the first pull which was 350mg from 100g of MHRB. IIRC, the other two yielded right around that much, so it was probably .7 or.8 percent. I've only done it once - that was the last of my bark at the time, so I'll have to give it another go and play around some more and keep better notes now that I have some new bark - it yields over 1.5% with the for the Masses procedure, so it should be interesting.
I assume the ammonia you're talking about is at the end of for the Masses? That's an artifact that I shouldn't have put in there. I was using it because I was working with the Marsofold tek which calls for an ammonia wash. It causes a lot of people trouble, and even when it doesn't, it's less effective than a non polar wash. I've gotten Erowid to put an addenda on to the tek saying this and it's on the DMT Nexus version too. Recrystalization is the way to go anyway.

Well that isn't too bad. Would be sweet to see some notes on it though. Can't wait for that, hope you don't leave us out of the loop. Yea the ammonia is just something that I personally wouldn't mess with for this, I can see that you agree. Just seems that other things would be better suited for the situation. Recrystallization is almost always the best way to go to get that nice product. Problem lies in the fact that most people just want to skip that step. They get there and decide that they have gone far enough and sometimes even get discouraged with the recrystallization process. That is the sad part. You are already there, just finish it. But I can see why people feel that way as even I have fucked up the recrystallization and ended up with half of what I was supposed to get and that will really piss you off. Even if you know what you did wrong to cause it, that still doesn't bring your product back. It is certainly an art in itself.

I'll post my results when I run it again. I plan on messing around with various clean up methods too and looking at breaking the stuff into it's various factions. That's my primary area of interest right now - studying the different effects that different degrees of purity and types of extraction have. The bioassay part of such experiments can get a bit grueling though.
For cleaning up For the Masses type extractions, a polar wash of the NP using alkaline water seems to be effective. It's essentially the same as an ammonia wash (ammonia can be used for the polar solution) but it's more thorough, as the ammonia wash only washes the outside of the crystal. Recrystalization is nice and glass shards are pretty, but for effect, slightly gummy yellow crystals are my favorite.

Yep that was what I was thinking. LOL What do you use to make your water alkaline??? Sodium bicarbonate or NaOH or KOH??? See I can understand why you like your crystals to be "Slightly gummy yellow" ones. I prefer the pure shards of product myself. Always afraid that shit gets left behind even with thorough washing. Plus it seems I can always taste a chemical taste with just washing. Some things recrystallization certainly doesn't really matter and you are just waisting your time trying to get to the shards of purity. Just losing some product and it was clean enough to begin with, such as with this.

Now your goal of studying the different effects of purity and how you arrive there is quite interesting. Wow you are doing all sorts of shit all the time. Nice to have people looking at things like that. Best part is that you are putting the info up for others to see. That is wonderful. Thank you good sir for taking the time. Means a lot to a lot of people, whether they say so or not, you deserve some credit man.
