Abstract:
The alkaloids of Colchicum arenarium were isolated from MeOH - extract in the form of neutral, phenolic and alkaline alkaloids.
Alkaloid separation was carried out by means of column chromatography, identification by means of common physico-chemical methods.
0.16 % colchicine, 0.13 % -lumicolchicine and 0.06 % -lumicolchicine were isolated from the bulb, and 0.29 % colchicine from the flower.
Besides ther were identified: a/ in the bulb: 2-demethyl-colchicine, 3-demethylcolchicine, demecolcine, 3-demethyl-demecolcin and three undefined components of following hRf values: 84, 29 and 16; b/ in the flower stalk; -lumicolchicine, -lumicolchicine, substance E1, substance C, substance F and two unidentified components hRf - 13 and hRf - 7; c/ in the flower -lumicolchicine, substance F, substance CC7, and two components hRf - 16 and hRf - 13.
