COLCHICOSIDE Usage And Synthesis

Chemical Properties	Pale Yellow Solid
Uses	A significantly toxic Colchicine analog with no anti-inflammatory properties.
Purification Methods	Purify colchicoside by chromatography through alumina and eluting with CHCl3, then recrystallising from Me2CO, m 275-280o (after releasing solvent at 180o). It also crystallises from EtOH; see colchicine. The tetraacetate has m 175-177o, [] D 15 -57o (c 1, CHCl3). [Bellet et al.
