Colchicum ritchii of Jordanian origin has yielded the three non-nitrogenous colchicinoids colchicone [1], 3-demethylcolchicone [2], and cornigerone [3], as well as the amidic (-)-colchibiphenyline, which in CDCl₃ solution exists as a mixture of isomers 4a and 4b. Ketones 1-3 may exemplify one catabolic route for the colchicine alkaloids, while (-)-colchibiphenyline [4a,4b], and the accompanying and previously known (-)-androbiphenyline [5a,5b] may exemplify another.
