The aerial parts of ANDROCYMBIUM MELANTHIOIDES yielded known alkaloids cornigerine, colchicine, N-formyl- N-deacetylcolchicine, 2-demethylcolchicine, 3-demethylcolchicine, demecolcine, 2-demethyldemecolcine, 3-demethyldemecolcine, beta-lumicornigerine, beta-lumicolchicine, gamma-lumicolchicine, androcymbine, O-methylandrocymbine, and melanthioidine. Of these, O-methylandrocymbine and beta-lumicornigerine are reported for the first, time.
