Swim was planning on a cross between A/B and a STB...

acidify rootbark to pH2 in crockpot for a given time to pull alkaloids into sltn

dump entire sltn including powdered rb into vessel

basify to pH 14+

add appropriate amount of DCM

lightly agitate

drain off DCM from the bottom of vessel

couple of quick, very mildly basic washes with H2O

evap

Swim is looking for full spectrum of alkaloids and will only recrystalize final product with warm heptane if he cant get the vapped DCM to solidify.

Unless the powdered rootbark suspended in the aqueous sltn falls down into the DCM layer, swim doesnt see where filtering would be nessisary during any point of this extraction.

If it does....  that would suck big hairy ones.
