Migrated topic.

Hey hi!!

I just found this place... its awesome!!!
Thanks to the creators for such a great initiative!!!!!!

Ok so,

Lets say one have some MH a lab available and enough basic knowledge to perform both A/B or STB extraction...
What would he prefer to do???

And the main question is why??

Those two proccess seem to be verry well documented and to give very satisfying results...
i know each step usually equal loss...
So by instic i would say STB is better...
Is this is anywhere close from experimented reality??
A/B is verry seducting too...

So what experimented peeps usualy choose for best result ?? (Time or dificulty is not really problematic...)
And if soxhlets are available would they use it??
and with what... Solvent?, acid?, base?, ionisated solvent? (A or B?)

Thanks for any help...
 
it depends on many things

SWIM already did a side-by-side STB and AB and the results were pretty much the same

you may loose some of the actives in the acid step, but not much.. If you do 4x boils or long simmers instead of 3, then there will virtually be no loss

One advantage of working with A/B is that the slurry of STB is quite messy, its a thick soup of very high pH.. Even to throw away its somehow a problem (for example when throwing down the toilet, loads can spill and make a bad smelling mess in your bathroom if you dont do it proper). With an A/B, once you get to the point of adding the base, all the solids will have been thrown away so its easier to work with.. The pH also wont need to be as high as with an STB

SWIM preffers STB for mimosa, though. For other things, (like 5-meo, or xtracting dmt from grasses or leafs) A/B is essential, but STB with freeze precipitation is quick, minimal work, and if one knows what he is doing and wears protective equipment, there is no danger of lye spilling in the eye or some stupid thing like that. Plus, as said, the result is basically the same, it is not more dirty or anything like that, its just as clean if you do freeze precipitation. Another advantage of STB appart from time and all that, is also no need to boil (so if you dont have an available stove to cook, you can still do it)

Both are very good practice for learning about extractions though.. Whatever SWIY feels best with, thats what he should go with
 
Both methods work it really does depend on how much time SWIY wants to put into it as STB is sometimes quicker, and how many chemicals one wants to use (amount of lye non polar solvents etc). Both can give good yields. SWIM personally thinks that A/B is nicer because you can avoid some problems with emulsions by defatting. Other then that STB works great.

Also people have been reporting good results with FASA tek so check that out too.
 
oh yeah forgot to mention defatting.. indeed thats one of the greatest possible advantages of an a/b

thats why I mentioned that for some dmt-containing leafy plants (chaliponga, chacruna, or also phalaris grasses), an A/B is the way to go (or the FASA way as burnt said)
 
Yeah i kind of like to try both method...

i think ill start with the A/B to gain that knowlwdge,
since its quite universal technique...
after ill try the STB...

Hey but is fumaric acid easy to get??
I never heard of it before comingn to this site...

seem like a nice method...
