Objective To study the chemical constituents from Disporum cantoniense. Methods Various column chromatographic techniques were used to separate and purify the chemical constituents and their structures were elucidated by spectral ananlysis. Results Sixteen compounds were isolated and identified as 3-maleimide-5-oxime (1), 4-methylene-5-oxopyrrolidine-2-carboxylic acid (2), thymine (3), adenosine (4), 5'-deoxy-5'-methylamino-adenosine (5), ethyl-α-L-rhamnose (6), bergenin (7), 4-hydroxy-2-methoxyphenyl-6-deoxy-α-L-talopyranoside (8), (-)-epicatechin (9), (6R,9R)-roseoside (10), 3-(4-hydroxy-3,5-dimethoxyphenyl) propane-1,2-diol (11), 3-hydroxy-5-(p-hydroxyphenyl) pentanoic acid (12), 1-ribityl-2,3-diketo-1,2,3,4-tetrahydro-6,7-dimethyl-quinoxaline (13), (6S,9R)-vomifoliol (14), 1-(3,4-dihydroxyphenyl)-2-hydroxye-thanone (15), and 1,2-dihydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)-ethane (16). Conclusion Compounds 1, 2, 5-9, and 12-16 are isolated from genus Disporum Salisb. for the first time, and compounds 1, 2, 5-10, and 12-16 are isolated from this plant for the first time.
