RÉSUMÉ
Objective: To study the chemical constituents from Scilla scilloides. Methods: The chemical constituents were isolated and purified by column chromatography and their structures were identified by spectral data. Results: Eighteen compounds were isolated from S. scilloides. Their structures were identified as scillascillin (1), 2-hydroxy-7-O-methylscillascillin (2), 4'-demethyleucomin (3), 5-hydroxy-7-methoxy-3-(4-hydroxybenzylidene) chroman-4-one (4), 4'-demethyl-3, 9-dihydroeucomin (5), 3'-hydroxy-3, 9-dihydroeucomin (6), 8-O-demethyl-7-O-methyl-3, 9-dihydropunctatin (7), apigenin (8), luteolin (9), chrysoeriol (10), 3-dehydro-15-deoxoeucosterol (11), 15-deoxoeucosterol (12), 4-allylpyrocatechol (13), norlichexanthone (14), drimiopsin C (15), 6-feruloylcatalpol (16), catalposide (17), and specioside (18). Conclusion: Iridoids (16-18) are isolated from the genus Scilla L. for the first time. Compounds 4, 7-10, and 13-18 are isolated from the plants of this genus for the first time.
