BTW guys, slight left turn, but if you want to extract the active compounds from an oil - mix oil/hexane/methanol in 1:2:1 volume ratios - mix it with a vortex mixer - centrifuge to separate the two layers and the methanol layer contains the active. From there you can dry it and test it by any number of methods like TLC.
Yeah most people are going to have no idea what you are talking about, though I like the post personally. Maybe you should give people a....simpler but longer explanation. I doubt many people have taken an organic chemistry course.
