The actives in calamus you want is not asarone, but something different. I believe it is not an alkaloid, but rather a phenethylamine-like substance without nitrogen. Asarone does suit this, but it is not psychedelic. Many related substances are also found in calamus, I think one of these is the active. It may also be that an unidentified compound is responsible. The actives is not alpha- or beta-asarone, that's for sure.
The psychedelic substance is soluble in cold water. It seems like acetone is pulling out the shit that makes you purge so bad, I think asarone is the responsible. You should check out
this thread from 69ron, it has very much interesting information.
I wish you good luck, can you keep us updated on your work? I have a feeling that it is an entheogenic treasure chest waiting to get opened inside of calamus.
