Abstract		Colchifoline and 2-demethylcolchifoline have been isolated from a neutral phenolic extract of the leaves, while colchifoline, 2-demethylcolchifoline and N-deacetyl-N-acetoacetylcolchifoline have been isolated from a neutral phenolic extract of the seeds of Colchicum autumnale L. 2-Demethyl and the beta- and gamma-lumiderivatives of colchifoline and the N-deacetyl-Nacetoacetylcolchicine have been prepared by acid hydrolysis and photochemical reaction, respectyively. A search for 2-demethyl-N-deacetyl-Nacetoacetylcolchicine and the beta- and gamma-lumiderivatives of colchifoline and N-deacetyl-N-acetoacetycolchicine as possible new alkaloids in Colchicum autumnale plant was unsucessful.
