alkaloids are soluble in ethanol
. It is also likely that ethanol will pull a lot of unwanted gunk from the seeds leaving a very resiny end product. After the alcohol
extraction one could perform an acid/base extraction on the alcoholic extraction to yeild a salt form of the alkaloids. But then one would still have to evaporate a large amount of water to recover the alkaloids, unless one elected to gas the non-polar pull while the alkaloid
is in the freebase form. However, gassing with Hydrogen chloride gas is only recommended for very pure anhydrous solutions usually containing only one active compound. Either way, a huge amount of poppy
seed would be required to make the process worthwhile.
EDIT: sorry, swim
thought the thread title said extraction from seeds.

Ok, let's try again. SWIM has also been interested in extracting pods without having to evaporate all that water. As SWIM stated above, it seems that a swimmer would still eventually have to evaporate a large amount of water if he wanted to obtain a relatively pure, stable salt form of the active alkaloids. If SWIF is satisfied with an impure residue of alkaloids and vegetative material, than the simple ethanol extraction would work.
After extracting the pods, one could warm the ethanol and filter it through a couple of coffee
filters to remove some of the plant material, tannins, etc. possibly yielding a more pure product.
