Edited: 250g MHBR A/B with n-Heptane. Cold and warm pulls

First pull from 250g MHBR tea (100ml solvent) using n-heptane. Pulled for 3 hours at around 3 hours starting at around 40c. (2l Erlenmeyer flask). Using a cheap magnetic stirrer at sub vortex.

I’m now running long room temp pulls, hopefully less fat.

The solvent was cloudy and yellow when i siphoned. Drops of fat left in the glas container before i poured into the pyrex dish.

I plan to use it for E-juice (w/citric acid). Try to just selectively scrape or try re-x?

EDIT: Adding summary from other thread to tidy up. (I'll continued here)
In summery, what i did this time:
  • 250g MHRB
  • 4 times 4 hour boils, with bit of vinegar (Not measured, 100ml perhaps each "wash"), filtered hot trough cloth.
  • Total 13-14 liter
  • Reduced down to 1.5 liter, a bit of sludge at this point. Which I kept. Once reduced, I've found there is allot of light in the sludge precipitated. (Learned teh hard way woth aya brews).
  • Based it with 110g dissolved Sodium hydroxide.
  • Started pulling with around 200ml

I ran 3 hours with the magnetic stirrer, 100ml heptane. Started while slightly warm still, perhaps 40c. Once i siphoned it was cloudy and as you can see some fat came with. The yield though surprised me. Almost a gram in 1 pull.

I have almost 3 cold pulls collected now, close to 300ml that i will freeze overnight. Im curious of the outcome. suspect low but clean yield. Its cold here now, so ive pulled at around 15C room temp. I may have to heat it up a bit tomorrow in water-bath and re-pull.

What I am considering now for next attempt:

  • Similar method to boil, but 3 x 3 hours. Perhaps filter better and decant before reducing as you suggested.
  • Split 250g in two extractions at around 2000ml.
  • Run a defat "pull" before basifying with the stirrer on warm or even hot "soup". Run till cold and discard the solvent.
  • If my yield on the cold pull attempts im doing now is very low, do several shorter "warm" pulls.
  • Then straight to mini A/B, or freeze and re-x?

Next week is warmer though, so maybe more cold pulls.

I may start a separate thread for my E-juice and modbox setup. (stuff on the way). My plan is to try the Citric acid Juice. But will save some spice for E-mesh once/if i get ready to blast.

I ended doing both. Does this look clean enough for E-juice? I was quite surprised how much on 1 pull though. With the goo, close to a gram. But it definitely smells like spice.

This is how im running the stirrer:

Most of the gunky stuff at the bottom is most likely DMT.. if its just going in an E-liquid that should be fine to use. Doesn't need to be pretty crystal. I think that looks more than good enough. As long as you are sure there are no extraction contaminants like NaOH or Naptha then it will be fine.
 
Mimosa spice is very clean. Even if it has a little colour or is a little waxy underneath the crystals, it should be more than potent/clean enough for use in your vape. The fact that your spice is white means there's essentially no plant fats in there. People often confuse the non solidified stuff at the bottom with plant fats. Its usually just DMT.. maybe another polymer, which @Transform is our resident expert on, should he wish to chime in.

Thank you :) That does make me feel better. Its certainly cleaner than my previous attempts. At least i know the boils was sufficient. 1g on a single 100ml pull. That spice must have been screaming to get pulled.

Sorry, I now have two threads running. Maybe merge ? (if possible). I

(DMT) If you could pick a solvent?

In any case, copying in my last summary:


In summery, what i did this time:
- 250g MHBR
- 4 times 4 hour boils, with bit of vinegar (Not measured, 100ml perhaps each "wash"), filtered hot trough cloth.
- Total 13-14 liter

13-14L is way too much liquid for 250g mimosa bark.. ! You'll have to spend an awful long time reducing your liquid - in which time the prolonged exposure to heat may cause some undesirable reactions to occur, causing potential complications during extraction. A litre or so per boil should be fine. I usually do 3x 45 minute to 1 hr simmers.. a fourth would really just be to help rinse out any liquid caught in your plant material.

110g of NaOH is also way too much for 1.5L of tea. You shouldn't need anymore than 20-30g really.. even that is overkill. You just want to aim for a ph of 11-12. The more lye you add, the higher temperature your extraction will be. If your solution is piping hot your bound to pull more impurities. And above all you do NOT wanna spill liquid with that much lye on yourself.. make sure you always have some vinegar handy when working with NaOH. Using amounts like what you mentioned is extremely dangerous.

Heat is really only something required with naptha and even then it just needs to be warm.. Heptane can pull DMT at room temperature (although a little heat will improve yield). Another advantage using a solvent that extracts at room temperature is you will pull less other impurities. Hot solvent will pull other unwanted stuff that likely wouldn't make its way over at room temperature. All this stuff is important to consider when doing extractions. A solvent that works at room temperature means you needn't add such large quantities of NaOH.

And your spice looks fine. I would re-x only if you plan on vaporizing the crystal. In a liquid that should be more than fine!

Edited above post a little btw

Thanks! I will adjust my method for next extract. In my shoes, would you split the 250g bark in two or just do a single extraction as I'm doing now?

Will freeze 4 cold pulls overnight.
 
Your yield might be slightly better if you do two smaller extractions, however 250g is a perfectly workable amount to use so its really up to you. You could do two slightly different extractions and compare yield?

Good idea. I'm not overly concerned about yield. After these extractions I suspect i will have spice for years. I think i will simply make a comparison with this extraction instead. So two 250g extractions. If I end up with 5+ gram in total I'll be more than happy.

I was initially planning to keep part of the tea for oral use, but I also have 250g ACRB and that's my favorite Aya analog plant. (Maybe due to NMT). I may even try extract 100g or so from that as well if I still have solvent.

Cool :) Let us know how you go with it all.

Pull 1: 1444mg
Pull 2-5: 2525mg

Still some goo, but the rest was fluffier and shinier. Almost entirely white and glittering :) Pull 6 done overnight got cloudy when i started the fan for drying the free dish, so clearly more left. Started pull 7 haha. When i decanted the solvent, it had plenty bits in it, so may have to try refreeze the same pull.

Maybe not necessary, but will collect all the yellow/goo and re-x at the end. About 1g of it now.

I will probably run shorter 50ml cold pulls next time, maybe 2 hour pulls?

Very happy so far, now I'm gonna try dissolving in PG/VG.

I did not add salt no, did allot of searching in old threads and many reported little or no benefit. But maybe something to add in next extraction.

i was wondering about this topic today, would be nice to find out the answer and listen some experience users, wheter adding salt is helping or not. i would really like to skip it, and under my skin i feel somehow that i could.

BTW. do you know your total yield from 250g bark, or not yet?

Not yet, 6 pulls 3.5 gram total so far. But seems like there is more there.

I just spilled 1 gram haha, made a bork when making E-juice. But I guess i can recover some of it by basing/pulling. The container tilted in the heat bath
 
@Kalitechnik

Pull 6 gave just 256mg, have a pull 7 to freeze. And now ran a 3 hour last warm pull. But I doubt there will be much more.

Total now is 3925mg, so 1.57%. Probably not much in the last two pulls. Will freeze it next week. But think I will discard the soup and start with new bark next week. 8 pulls should be enough lol. But Ill wait until I see what the next two pulls give when i freeze it next week.


I'll make a few changes for next extraction. (same bark from same vendor)

- Shorter 50 mil pulls instead of long 100ml
- Add salt
- Less lye, ill use strips to get it to around PH 12.

Pull 1: 1144mg
Pull 2-5: 2525mg
Pull 6: 256mg
Pull 7-8 ?

Hey!
Roughly 1.6 yield i think is very nice. I would say that this is a confirmation for me that salt is not so needed. Would like to hear more opinions though, and results from side by side test.
