Forensic Sci 9:195-203 - Oliver JS, Smith H, WIlliams DJ (1977) tells us that putrefying bodies have been shown to develop non-negligible proportions of b-phenethylamine under the right conditions... namely, kill it, chill it, inject sodium fluoride at about 1mg/L into the bloodstream, manually massage and then allow to rot for about a week before draining the blood and commencing electrophoreisis... these were studies on human cadavers, but I'm assuming most higher mammals would do the same thing... i was thinking maybe bulk-buy baby rabbits from irresponsible neighbourhood children, or just breed my own and gas 'em with sarin, which would also nicely push out the anticholinesterase balance to our favour...
cruel and unusual, but possibly viable! some human cadavers 3 weeks putrefied in a 14*C cooler were detected to have b-phen up to 193mg/L
it's a small yeild, but easily obtained and very repeatable.
apparently natural concentrations of 'wild' cadavers peak out about 5 hours postmortem but cholinesterase rips the shit out of everything after that... so chilling promotes higher production and NaF inhibits breakdown... internal surface flesh from the superior and inferior vena cava and right heart also bears marked additional concentrations
I wonder how hard it would be to steal a vegetable body from a hospital, set up a life-support system in my lab and jsut tweak his biochemistry to the desired enzyme stats and start pushing apiole or safrole into his liver... but then again, rabbits are far more efficient for that particular conversion... "Determination of biogenic amines in wine after clean-up by solid-phase extraction" - O. Busto, M. Mestres, J. Guasch and F. Borrull says that simple ion exchange cartridges and HPLC is pulling 50ug/L of phenethylamine derivatives from commercial wines.. with a little adaption, it shouldn't be too hard to be cleaning at least 100mg/L of beta-phenthylamine from a decent cadaver. most bodies are about 11% blood of mass, so for your average human male we're talking 4.7-5 litres... 500mg of b-PEA suitably preserved with a dash of NaF is enough for a little under 300mg of molly, via the easiest (but not the best-yeilding) pathway... with a lot of good equipment I could probably get 90-100% conversion rate! So, two bodies under ideal conditions would give me a gram of pure MDMA, which is enough for, say, ten good pills. In my awful, shitty city pills of that clibre go for up to $50 each. $500 more then covers the cost of a brick to hit hobos with, plus it's really freaking cool.
then again, most processed cheeses can be carrying up to 58mg/kg of b-PEA, according to "Biogenic amines in processed cheese available in Egypt" - International Dairy Journal Volume 6, Issues 11-12, November-December 1996, Pages 1079-1086 (M. M. El-Sayed) and cheese is a lot easier to hold onto then corpses...
But oh how I LOVE to recycle!
