to extract anandamide you should find the boiling point
mix chocolate in a water solution
but the ratio would have to like little chocolate to a lot of water or like 40:60
then you evaporate the solution
and at the different temperatures you would move the tube
in which the liquid evaporates from to different containers...

so one would be water (100°C)
cocoa (what ever taht boiling point is)
anandamide (boiling point)
then all the other ingredients in chocolate

would have to have a chem set to work it
but thats the way i know how to separate chemicals
in liquid solutions



sounds like its not worth it, unless you had a day of nothing to do
