Conclusions

FromColchicum luteum Baker collected in the gorge of the Sazan-Ata River in the Chimkent region have been isolated the known alkaloids colchamine, 3-desmethylcolchamine, 3-desmethyl-β-lumicolchicine, colchicine, 2-desmethylcolchicine, β-lumicolchicine, N-desacetyl-N-formylcolchicine, and luteidine, and the new alkaloids L-5 and L-6. The first three bases have been obtained from this plant for the first time.

Paper chromatography showed the presence of another three new alkaloids with R f 0.38, 0.40, and 0.86. On the basis of UV, IR, and NMR spectroscopy and chemical reactions, the structure of 2-desmethylcolchiceine has been proposed for the alkaloid L-5.
