I was supervising a lab and a student wanted to extract the capsaicin out of peppers. We took around a pound of habanero peppers and in a few batches, froze them with liquid nitrogen so we could grind them in a mortar and pestle. After that we placed the ground up peppers in a half liter hexane and stirred for 2 hrs. Then evaporated the hexane after filtering. We were left with around a milliliter of this oil and it was hot, but not death inducing hot. I know they sell the pure crystals and am curious if anyone actually had placed a very small one on their tongue?
