Some other woman I met told me about 0.97% total yeild, starting with 200 g MHRB, doing a typical A-B extraction at room temp in a gallon-sized, glass wine jug.
I guess this is normal if you're as picky as she is, but there was an interesting outcome too, in addition to her using very little volumes of everything, all the dmt from 200 g MHRB came out in < 3.5 litres of purple extract.
There were three acid soaks of the pulverized MHRB, using 1600- 1750 ml of pH 1.8 water (just 5 ml of 35% HCL in 7 cups of deionized water makes a pH of 1.8 - !). These combined were less than 5.0 litres of purple extract, but she only needed to do two acid soaks making 3.3 liters to get a 0.97% yield !.
The purple filtrate from 1st acid soak (1.6 litres) yielded 1583 mg of mostly white dmt (0.79%). This was extracted 4 times with naphtha once basified.
The second acid soak of the same 200g MHRB sludge used a little less pH 1.8 water. But after basifying and with 4 naphtha pulls, it yeilded another 356 mg making the total yield
(1583 + 356 = 1939 mg or 0.97% ! This was done by evaporating all the NP solvent.
The third acid soak of the 200 g of MHRB-sludge yielded 0% dmt after 3 naphtha pulls ! Swim had never observed this before and in the end she could have gotten >0.9% yield with just two acid soaks making her have to handle < 3.5 litres of purple extract !
The MHRB sludge was left in the jug between soaks - after 12 hours the jug's water was just poured slowly out through the filter cone (funnel with
http://www.whatman.com/products/?pageID=7.25.5.11 papers). So there's no mess to handle - just resoak the sludge, shake the sheet out of it, and then discard the gunk after second or third soak.
The soak period swim used was 12 - 24 hours, and the glass jug with the ~2.0 litres of acid and MHRB was shaken at every occasion, as vigorously as possible. Swim said that at room temp, slowly the pulverized MHRB floating in a super acid environment was going to give up it's dmt easily - mosly due to the extensive grinding, but the wet acidity was digesting the dried bark cells appart all the time. Doing the Acid soaks at room temperature didn't likely destroy the"Red Jungle Spice", either, she thought...
Her lye-solution used to basify each jar of purple extract was this: in 300 ml of hot water dissolve 80 g lye - this makes a solution with a pH of almost 14 !.
Then for each 5-700 ml of filtered, purple extract just add 20 ml of the lye-solution and swill to see the colour change blue-grey, then jet black (30 ml are way past pH 11.5) .. Swim Basifies to pH 11.5 with just 20 ml of the lye solution ! She puts a layer of 80 ml naphtha per 600 ml extract on before the lye-solution is added, and does 4 pulls.
That was some good purple bark she had !
, he performed somehow the tek described above on 245 g of purple powder.
