/diy/ - Do It Yourself

collect apricot seeds during the right season, the amygdalin content varies though the year and can be as high as 5% of the dry weight of the seed.
It is probably advantagenous to break the husk with a nut cracker, a plier, etc. and cut the softer inner material to smaller pieces.
Extraction of amygdalin can be performed by

Immersing the material in methanol and subsequent ultrasonification.
Soxhlet extraction with methanol
Reflux extraction in water in the presence of citric acid.

Removal of the solvent in vacuum will yield a crude material with significant amounts of amygdalin.

Mix the liquid with ammonia and paint thinner, in tupperware and come back after 2 minutes, and you should have a whole tray of a bathbomb, cut round shapes out of the tray and viola you now can use it safely.
Then sniff the mixture afterwards to be met with a nice rosy smell.
