Good day. I followed Cyb's Max ion tek, but left the MHRB in acid soak for 2 days (pH 2-3), and basified for around 15-18 hours. I used 50 grams of powdered MHRB, and didnt use excesive heat. 75 mg of N,N-DMT (without re-xtalization) is a embarrasing yield. Any advice? Thank you in advance

How many pulls did you do on the bark?

Maybe the bark itself is weak bark? Have you extracted from the same batch before this with better results?

Thank you for the reply. I did 6 pulls. This is the first time i use this bark, this is so sad.

Used a total volume of 1 L, 80 g of NaCl, Basified until a pH of 13 with NaOH, both ragent grade.

Hmm I would say weak bark if youve had success with that tek before, although that pH seems a bit low and for quite long.
I wouldnt be suprised if some sellers actually cut the bark with something.

Thank you for the reply. Then, I will do it once again letting it soak in acid for less time.

How big were the pulls, and did you freeze or evap?

What solvent are you using? i also have low yields. Slightly more than 75mg but definitely no 1%+. But i am using whole root bark instead of powdered.

Powder it up.
It will take a lot of cell lysing to extract from whole bark...give yourself the best chance possible.
Get out your hammer and blender.

OP, as stated, we need more info before a diagnosis can be made.

6 pulls, 50 mL of hot naphta (each one) per 50 g of powdered root bark. First I did evaporate to 40% of naphta volume and then I left it in the freezer at max power for 24 hours. Thank you in advance.

how well did you mix the pulls? If you didnt mix them very thoroughly, I'd try to do a couple more very thorough pulls (adding more lye and salt before)

i'd evaporate the naphtha down some more, to maybe 20% of the volume now, and freeze again.

Also I'd add some more lye and salt to the bark mix and do another warm pull and evaporate it down to just a tiny bit and freeze.

If nothing of this yields more, I'd guess its bad bark

I mixed the layers by rotating the reactor up and down for around 30 seconds and letting it to settle, then did it again 2 more times (each pull), do I have to SHAKE it? Also, should i add enough lye to get it to 13-14? it's still in 12 I guess.

Definitely add lye to get to pH 14.. Dont need to shake but you can turn it upside down a few more times

Thank you very much end, i will buy some more naptha.

i would say the same.. MORE Lye..!sounds like the dmt was not really converted to its freebase-form, yet, and therefore wasn't captired by the Naphta..??? Just a thought..

Yeah more lye with salt, change naptha and no shake or rattle just a roll my mate has just got frustrated with his and made an emulsion by shaking vigorously so dont do that..
