I was teaching an organic chemistry lab and the final 2 experiments were let the students do what they want. I worked with this one student: We cut up a bunch of habaneros and poured liquid nitrogen into a crucible to crush them up fine (more surface area) and then added hexane and heated up (a little) for 2 hrs then we distilled off the hexane and vacuum evaporated the rest. The resultant oil (not much, about 1/4 teaspoon) was fantastic with just putting a pin in the oil and touching your tongue being quite enough for both a burn and a great taste.
Sidenote: I looked up pure capsaicin powder, it is like 300 dollars a gram.
