| | COLCHICOSIDE Usage And Synthesis |
| Chemical Properties | Pale Yellow Solid | | Uses | A significantly toxic Colchicine analog with no anti-inflammatory properties. | | Definition | ChEBI: Colchicoside is a carbotricyclic compound, an alkaloid and a member of acetamides. | | 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.
