Fw: Fw: How to extract colchicine

I don't know if this helps but Gloriosa Superba is the actual source of most
modern colchicine - and there are several papers on Google about using
Gloriosa Superba instead of commercial colchicine (try "Gloriosa Superba
colchicine extract"). Seems it is extracted with ethanol.

Another case where the extraction is easier from a different plant than the
one that first had the chemical characterised from it. At uni we extracted
caffeine from tea - apparently an easier source than coffee !

Laff track.

Jim, I thank you for your response -- indeed I am about to write you offline
asking to borrow an image -- but I did ask for online information about how
to extract cochicine. In the 1960s I was not a subscriber to the North
American Lily Society's journal, and as I type I am snowed in on a mountain
far from any library, research or otherwise.

Someone reading this knows how to extract colchicine in a simple way, but
might not wish to respond online. Please reply offline if you prefer.
