So I decided to try an A/B on some of the shredded bark I recently got from MH-UK. Didn't think I would have much luck, seeing as I have read around and it seemed like people weren't getting the desired results. I had done a 75g STB extraction a few months ago and got almost nothing out of it. Twuz poor to say the least.

I used 1:4 ratio of vinegar to water... 4 x 1 hr boils with 120g of bark... combined and reduced down to about 230ml. I used a HDPE2 milk jug as I said in a different thread, it made pulling the solvent so easy! I did two 80ml naphtha pulls and combined, reduced a bit with a fan, and then put in fridge for 12 hrs and freezer for 24. Most of what came out of the base soup was in the first two pulls, as the third and fourth pull had barely anything.

Final yield (minus last pull in freezer that looks very sparse): 1.045 grams ... Which isn't bad due to it being shredded bark and not powder. According to Adenium, shredded contains 30% less alkaloids.

Don't think i'll recrystallise, as i will probably make some enhanced leaf or changa with it anyways.

That definatly looks good as it is...



Does he mean that this specific batch of shredded bark yields 30% less then the powdered bark? I don't see why shredded bark would contain less alkaloids??

He says this on the Adenium site regarding their shredded bark: "Bark pieces are cheaper then our powder because filler fibers are removed when powdered, so powder is about 30% more potent/weight."

Interesting..

That looks like it would make some scrumptious changa, enjoy.

Nice work Kermit

My last extraction using shredded from mh-uk was very disappointing! Maybe i should look into doing an a/b next time.

Looks tasty

My latest extraction i did with shredded i first cooked with very acidic water for two hours then i used a hand blender to break down the material as much as possible, then cooked for another hour.

After that i based it and pulled about 1,2% with warm heptane.

After that i let it sit for about 2weeks then i pulled about 0,5% more with toulene.

All the spice was preety clean although i cleaned the toulene pulls a few times just to be sure i got no toulene in my spice.


This bark was from celestial source.

Very nice crystals, congrat

Yeah man, this shredded barque is crap compared to the powdered. I get way less alks. Oddly, my batch seems to contain way more fats/oils, naphtha takes longer to separate from the basic solution. The latest bark from MHUK (same place the previous was from) seems to be cleaner, solvent separates very quickly and remains clean. I wonder if a defat would actually be useful for that batch of bark then? People say it's unnecessary, but I have my doubts here.

Is this kind of cooking recommended for any tek, or is it for only specific tek?

I got only about 0.4% yield from supposedly high quality shredded bark and I wonder if this could help the yield... Any info on this method?

For me, the acid cooks made all the difference. I think you'd have to shake the base soup for a week to break down the bark enough for a decent pull when going straight to base. I literally had nothing in my first pull of 75g of blended, shredded bark. It's all about A/B's for shredded. The amount of liquid used (after reducing) is so much less than with an STB, along with the amount of lye needed. Everything about it = Win.

I'm going to boil the spent bark again for a few hours just to see if anything is left. Might as well, seeing as others have reported decent results by doing this.

Orion, i don't think a defat would have made much difference in my case. All came out quite clean in the end. Just finished making some mint, lemon leaves (lemon verbena?), and caapi changa. Smells yumski

I would like to do q21q21's tek(lime base), so is it recommended to boil the shredded pieces(about 1-2cm) in acidic water before grinding them in coffee grinder?

I'm just wondering if it would help my yield...

And should one skip the "add vinegar" step if doing an acid cook?

Any1?

Boil it after instead, no need to boil it in vinegar if you gonna powderize it.

Do you mean boil it after it is grinded?

Can someone explain why this acid cook can increase the yield and how many hours and how much vinegar one should boil it with?

thanks

I ground the bark a bit in a blender first and the bark remained quite fibrous to then do 4 x 1hr boils (using fresh water/vinegar for each one). Not sure how a q21q21's tek(lime base) tek would work. You might as well try it out if you have the materials.

OK, I will try.

So do you remove the water from the boil or do you just add the fresh water into the mix?

But in general, is the purpose of the acid cook to make the whole bark more acid?

I'll try it like this:

Boil grinded MHRB powder with vinegar for some hours.
Keep the remaining liquid with the powder and add base(lime) to the mix.

Hopefully it will yield more than 0.4% it yielded without boiling. The tek worked much better with pre-powdered!

You have to drain the water and leave sediment behind after each boil. Save the collected tea in a separate container and once done with all the boils, you can put the mimosa tea into a new pot to reduce the liquid to a more manageable amount. Easy peasy lemon squeezy

So would the whole DMT amount be transferred into the liquid?

I was thinking mixing the liquid and the bark with the lime just to make sure everything gets basified...

It could be a completely different story if using lime. I haven't ever done a lime tek, so another fellow nexian should chime in on that one. I am guessing it could work, as long as you get it to the right consistency, but getting rid of all the bark and sediment might make that particular task difficult. Better to use a more water soluble base like lye after doing acid boils to make the tea basic enough, but i can't compare it to the other tek, so i could be wrong. Sorry for not being very clear.

Do you not want to use NaOH and stick to a food-safe tek to be safer and not use nasty chems? My hat off to you for doing it. The tek might work better on completely blended shredded stuff compared to normal STB's, as calcium hydroxide is a really strong base. May work if you just stick the tek after blending the bark, but just leaving it in the base solution for a while longer to make sure it's done the job.

I am kinda curious to know if adding lime straight to the tea would work or not. I am sure someone's tried it.
