Reaction of decetylcolchicine (2) and colchifoline (3) with diacetyldihydrofluorescein (1, DADF) afforded the corresponding amide and ester derivatives, converted on TLC-plates after exposure to ammonia and iodine vapors into red colored pigments. This reaction, also observed with DADF-derivatives of codeine, quinine and mescaline is highly sensitive. The red pigment produced from the DADF-ester (6)
