bad yield from ab

[mb123456]

A friend attempted an ab on a kg of mhrb and yielded only a gram. Where could the other 9 or so grams be?

He thought he did everything correctly but maybe not. His steps were

2 simmers in vinegar water solution for an hour each.
He then filtered and added lye.
Then did first naptha pull and got a little less than a gram
He did 2 or 3 more pulls with very little coming out.
He also did a pull with xylene and got a little jungle which he washed with bestine. This only gave a tiny amount though.
He also used the old powdered bark and added lye to it and did a pull on it. this also only gave a worthless amount.
He thinks he could get a half gram more at most doing multiple more pulls on all solutions.

A few issues he think could be that only 500 grams or so of lye were used. He added lye to all of it until it turned black and then a little extra, though. Was this enough?
He also added the lye straight to the solution without premixing with water. He did it slowly though.
the first naptha pulls were still yellow after a two day freeze precipitation. Does this need to be evaped.

He has done lots of hours researching on the nexus and cannot figure out what is wrong. Could that much be an oxide not pulled by the light np solvents? He got the powdered bark from a vendor in Southern Cali. Or could it be bad bark?

Any ideas to get the remaining amount out or telling where he messed up would be greatly appreciated

To not even have 3 dollar pH indicator strips when attempting a KG extraction seems cray cray to me. Spend 3 bucks and end the mystery. When doing a freeze prec. you want to evaporate the solvent down to a pretty small amount, like if you had 1000ml of solvent evap it down to 100-200ml. Don't use heat to evap, you'll oxidize the DMT and get goop.

mb123456, this is not an in offence to swim, but perhaps that is a good thing he only achieved that yield and perhaps this is saying something. No ph strips?

How long was your naptha allowed to sit and mix for? That is very critical.

Thats a hell of alot of surface area the np sol has to come into contact with and if you left it for just say a couple of hours and no stiring or gentle regular aggeation. It could be unlikely that all the gooodies had enough time to cross over.

Perfect your smaller tricks, then work up. Not to have ph papers and test your solution, well school boy error there imo Coloured naptha is just other plant fats n crap that has had the chance to cross over.
