RESUMO
Objective: To study the chemical constituents from Disporum cantoniense. Methods: Separation was carried out by ion exchange chromatography, medium pressure MCI column chromatography, ODS column chromatography, gel column chromatography, preparative and semi preparative liquid chromatography; The structures of the compounds were identified by modern spectral techniques such as mass spectrometry and nuclear magnetic resonance. Results: Eleven compounds were isolated and identified as 2’-β-D-glucopyranosyloxybenzyl-6-α-L-(4’-O-acetyl)-rhamnopyranosyloxy-2-hydroxy-3-methoxybenzoate (1), 4’,7- dihydroxyflavone (2), palmatine (3), marmesinin (4), 4’-O-β-D-glucosyl-5-O-methylvisamminol (5), nodakenetin (6), 2-aminopyridine (7), tenuifoliside A (8), neosakuranin (9), 2″-O-rhamnosylicariside II (10) and baohuoside I (11). Conclusion: Compound 1 is a new compound named disporumoside, compounds 2-11 are isolated from the genus of Disporum for the first time.
