How to improve my yield?

[Psilocybrina]

Hello all. I have extracted DMT twice now, the first time doing an A/B using Xylene as NPS which doesnt freeze precipitate so I had to heat it and deal with fumes.

More recently, I've used an STB using Naphtha, and the product itself is very good quality but I believe my yield is a bit low, and I am wondering how I could increase it for next time. I've been told I can expect a yield of around 1g but my result was .358g. Below is an edited version of the tek I used, making it more specific of how I did it. In the original tek it uses one 1000mL erlenmeyer flask (which I have since gotten), but when I did the extraction I only had two 500mLs and cut the math in half. Thanks for any help!



2x50g powdered mhrb into two 500mL add 300mL water to both then add 20 grams pickling salt to both. Saran wrap and rubber band over the flasks and shake them until all powdered bark is dissolved and wet. Then I take 150mL of water and slowly add 17.5 grams lye wearing safety goggles and gloves. Mix until dissolved then add to the flask. (Obviously repeat for the other flask). Then went to work, 7-8 hour shift. Added 30mL naphtha to both flasks then cover with Saran wrap and rubber band over the flasks and shake. let it sit and separate for 15-20 mins then pull the solvent. Then add new solvent and repeat 3-4 times total. Water wash all of the solvent. Put solvent into a Pyrex dish and seal tightly with Saran wrap over it and freeze overnight. Pour off solvent and let the dish dry.

What if you did an A/B with Naptha and then did your last pull or two with Xylene? Or even just did the STB and did the last pull or two with Xylene. I do that and the Xylene gets me some quite active goo. (I also evap the Naptha on top of the Xylene after freeze precipitating)

I have a small unattached garage I use as a shed, so I just set it out there in a corner for a week to evap. Honestly though, I've evaped small amounts of Xylene in a corner of the basement. Stuff's nasty to work with while pulling, etc., though.

First off there's no guaranteed yield for any batch of MHRB, it can be from 0% up to 2% plus, depending on growing conditions etc.

The main change between your stated procedure and the teks I've used is that I will shake up and let separate each batch of solvent several times in a row, this allows the full amount of DMT to dissolve in the NPS. Your writeup says you only shake once then pull off after separation, try five or six "shakes then wait for separation" per 30ml. The way you say you did it will likely result in much less saturated NPS, so you don't get the full amount out when frozen.

Try combining 3 x 30ml pulls then washing and freezing, don't discard the soup yet! Then use the solvent you poured off to do another set of 30 ml pulls ( mixing several times for each one ) and repeat this process until the last freeze didn't produce enough DMT to make it worthwhile.

Also, saran wrap will likely dissolve plasticisers into the NPS if it comes in contact, so use a different way of sealing the flask that is NPS proof. Like a PTFE sheet around a rubber bung perhaps.

Psilocybrina may have gotten the wrong impression of yeild from me in chat, refering to my personly batch of MHRB I have been pulling from.

I think a crucial step I missed was heat during pulls and hot water during the water wash. I am doing another extraction now, also with 100g of NaOH. I am also going to freeze precipitate each pull instead of combining the four. And I am no longer going to cover and shake with saran wrap, twirling instead. I will update my results when its finished!

Here is my updated method for anyone stumbling across this if I get good results.



100g powdered root bark into a 1000mL Erlenmeyer flask
Add 45 grams picking salt.
Wear goggles and gloves.
Take 850mL water, slowly add 100g NaOH (Lye).
Mix until dissolved and then slowly add to the flask.
Twirl the flask lightly until all the bark is dissolved and wet.
Everything should turn black indicating the PH is pretty close if it doesn’t turn black slowly add more lye to a bit of water until it turns black.
Wait atleast 24 hours, twirl the flask occasionally.
Add 35mL of naphtha.
Prepare a water bath. Put the flask inside and heat up the flask to 50-60 degrees Celsius.
Twirl for 2-3 minutes, pull the solvent with a glass pipette.
When solvent is collected, put it in a beaker with a third amount of HOT water.
On the bottom will be water, in the middle will be impurities, and the top will be solvent.
Use a glass pipette to twirl around the solution and you will see the impurities collecting in the middle.
Collect in that middle section and put the water/impurities in one container, and solvent in the freeze dish.
Leave in freezer for 8-12 hours.
Once you take it out, immediately dump the solvent into a container. Use a fan to help it dry.
Repeat pulls until the yield is less than .1g.
