Pentane is a hydrocarbon, one carbon longer than Propane, one less than Hexane. It's a common constituent of Natural Gas Liquids (NGL). Basically it sits in between Natural Gas and Gasoline in the world of organic chemistry. The study you mention used pentane to extract hydrophobic volatiles from American Elm sawdust. They could have used something else like carbon tetrachloride, but pentane is likely considered safer than a chlorocarbon like carbon tet.

Honestly, after reading Punaweb for a while, I don't think we're far off from the Salem Witch thing. Bad rye is also theorized for many other events. Rye mold (ergot) is a source of a precursor for LSD, which explains the association with bizarre behaviour. I'm not sure what the excuse is for many on PW, but it sure is entertaining.
