Abstract:
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.
